Sidestand Safety Switch Rewiring 2.1
Contents
1. lights were all on the neutral light was green the emergency cutoff switch was in the run position but nothing was transpiring when pressed the start button Having been riding for years could not even get the damn thing started at the dealer how embarrassing This is after told the salesman Yes own another Ducati a Monster and know everything there is to know about Ducatis Looking at the salesman s face it was like listening to a loudspeaker of what was going on in his head His lips were not moving you could not hear any sound but his voice was deafening This bozo is just trying to go for a test drive He will probably crash the damn thing in the first corner He probably has not been on a bike before am not even sure if his motorcycle driver license is real should take a look at that thing again Trying to show me what an idiot was he kind of nudged me aside and said let me start it for you SIR By this time was sweating passed him the key and stood to the side waiting for his next you idiot joke after he started the bike To my surprise he could not get the damn thing started either By this time my embarrassing cold sweat was drying into and you work here at a motorcycle dealer look He was turning the ignition key back and forth pushing the gear lever pulling in the clutch but nothing mean nothing was happening He decided to go inside to talk to the mechanic or whomever he could fin2. and the engine will keep on running really think this is the way the safety switch circuitry should have been designed in the first place This will keep the original intent of not allowing the rider take off while the side stand is down and it will also allow people to warm up the engine while the bike is on the side stand May be Ducati thinks their bikes can get into gear by themselves What if that is true think should stop writing and go back to the garage and undo the wiring back to the stock setup No no and no cannot go back to the stock setup It is going to drive me mad in no time if do that So keep on writing By the way Evoluzione sells a solution similar to what is described in this document for a lot of different model Ducatis including ST4 Their kickstand starter bypass harness function wise is almost identical to what is described here and it sells for 40 plus shipping You can see their product by clicking here Considering what one gets even at 40 it is not a bad price It will save some time therefore money using a pre fabricated part versus shopping for parts soldering them and fabricating the bypass wire People who like the functionality described in this document and are sick of how their bikes side stand switch works in stock form should call these guys hear that Ken Zeller the owner of Evoluzione is also hell of a nice guy But am an motorcyle enthusiast and a home mechanic junkie what can
3. side bracket it is not that heavy duty and has slightly bent it had a tough time aligning the bracket with the holes when removed the bracket for some other maintenance work On my Monster had a retractable side stand stand would retract once you straightened the bike that originally hated eventually got to like the retractable side stand a lot after the initial what the heck is that impression Although Monster s retractable side stand had its own issues still liked it But never got used to the ST4 s side stand safety switch operation It was time to do something about this started researching this issue and found some very useful stuff at Bob Cowin s Ducati Index under Tech Tip section What ended up incorporating on my bike and later documenting here is a more detailed version of what was described at the Ducati Index s Useful Tip section By the way there was no Legal Disclaimer there how irresponsible and inconsiderate of people Solution Description The main goal is to rewire the side stand safety switch so that the bike starts while on the side stand and in Neutral Additionally 1 If the bike is not in neutral the engine will not start 2 If the bike is in neutral and the engine is running putting the bike in gear while the side stand is down will kill the engine 3 If the bike is in neutral and the engine is running putting the bike in gear while the side stand is up will have no effect
4. stock form I will not be able to start the bike on the side stand A2 If the diode fails causing the bypass wire to be closed shorted the neutral light will stay on if the side stand is in the up position regardless if the bike is in gear or in neutral This will be an inconvenience for me since will not know when am in neutral but did not consider it to be too big of a deal It this happens would know that have a bad bypass wire If push comes to shove can always pull to the side of the road disconnect the side stand switch short the two wires on the wiring harness side and it would act like have a bad side stand switch When get home can then replace the bypass wire B What if something happens to the side stand switch will be stranded somewhere As described above connected the wire from the neutral switch to the side stand part of the connector and not the wiring harness side of the connector The side stand switch can also fail in two ways 1 If the side stand switch fails in the up position Sensor open position do not have to do anything The bike will start and run regardless of where the side stand is The stock switch without any modifications will do the same thing just have to be careful not to take off with the side stand down 2 If the side stand switch fails in the down position sensor close position my bike will start but will not be able to put it in gear The moment put it in ge
5. 2 Two inline T branch Connectors at purchased them at Fry s Electronics for 1 49 for a package of 5 These allow you to branch off a wire without having to cut the wire in half 3 Some electrical wire had a spool of 18 gauge wire in the garage that used approximately 2 5 feet 70 80 cm of 4 Some electrical tape or heat shrink tubing Mental Note to self f the wife asks how much all of these stuff costs for once tell her the TRUTH and nothing but the truth Even show her the receipts Installation The first step was to incorporate the diode into the wire that was going to go between the neutral switch wire and the side stand safety switch wire The purpose of this diode is to allow the power to go in one direction only If that is not done the neutral light will stay on at all times when the side stand is up even if the bike is in gear The diode is direction sensitive There is a stripe on one end of the diode needed to make sure that the stripe was on the neutral switch side and not the side stand safety switch side To do this cut the wire about 5 inches 12 cm from one side This was going to be the neutral switch side soldered the diode inline making sure that kept the diode in the right orientation The 1N4001 Silicon Diode soldered inline in the connecting wire The direction of the diode is critical in the proper operation of the whole rewiring The silver stripe at the right hand side

7. ar the bike thinks the side stand is down and it will kill the engine If this happens can disconnect the connector the bike will not start when the switch and the bypass cable are disconnected can then short the 2 wires on the wiring harness side of the connector to start the bike Again similar to the first case just have to be careful not take off with the side stand down Another Mental Note Put a paper clip in the tool box for emergency shorting of the two wires in the side stand switch connector One 1N4001 Silicon Diode 0 30 Two T connectors 0 60 2 5 feet of wire heat shrink tubing and electrical tape 0 25 Looking at the bike warming up on the side stand while am putting my helmet on Priceless
8. d in the shop Not having anything to do opened the USER MANUAL Here it was under Starting the engine section Warning The side stand must be fully up in a horizontal position as its safety sensor prevents engine start when down At least it was documented This time sat on the bike kicked up the side stand pushed the starter and the bike started right up By this time could see the salesman at the backend of the store coming toward the street with one of those I still do not have clue looks Granted this was a used Ducati at a Honda Suzuki dealer and these guys did not know anything about Ducatis but you would expect they should have at least known how to start the bike Anyway to make the story short as you can see by now ended up buying the bike At the time that bought the bike did not think too much about the side stand switch thought it is one of those things it is probably there for a good reason As weeks and then months went by this side stand safety switch started to get under my skin and it got under my skin badly Trying to warm up the bike had to put the bike on the center stand which is not the easiest thing in the world either Even today after having owned the bike for almost 4 months still have to rock the bike four to five times to get it on the center stand damn hate that also think pulling such a heavy bike up on the center stand has kind of put some pressure on the pannier left hand
9. in this picture needs to be on the Neutral switch side of the connecting wire a Silver Stripe After soldering the diode placed a 1 8 heat shrink tubing on the exposed area of the wire and heated the tubing to insulate the exposed wires later moved one layer of heat shrink tubing on the whole wire for extra protection To be able to tap into the Neutral signal needed to locate the Neutral Switch on the bike On my ST4 the neutral switch is located on the right hand side of the bike in the rear of the engine close to the rear shock am guessing on the St2 the neutral switch is in a similar location The neutral switch operates with a single wire It uses the chassis for ground When the bike is in neutral it grounds the signal coming from the neutral light bulb in the light cluster above the dash panel This causes the current to go through the bulb and therefore turns it on To tap to the wire that goes into the neutral switch first removed the connector from the switch then used one of the T branch connectors on the wire about 5 inches 10 12 cm away from the connector When the connector is pressed closed there is a metal U shape piece in the connector that goes through the insulation material of the wire and it makes contact with the conductive metal part of the tapped wire This method does not actually cut the tapped wire connected the bypass wire to the other part of this connector When the Connector
10. is closed it looks like this then passed the wire between the vertical cylinder and the horizontal cylinder to the other side of bike trying to make sure ty wrapped them to something to keep them away from the engine pieces that might get hot when the bike is running for a while This was done so that can get the other side the wire close to the side stand switch harness The side stand safety switch on the ST4 and probably ST2 is connected to the bike s wiring harness via a connector On the wiring harness side of this connector there are two wires One is Black Bk ground and the other one is Blue Black BBk signal Looking at the wiring diagram in the bike s user manual the side stand safety switch is marked as switch 35 The wire from the neutral switch needed to be tapped into Blue Black BBk signal wire tapped into the switch side of this connector not the harness side of the connector made sure that was mating the bypass to the wire that was mating with the Blue Black BBk signal wire on the wiring harness side piece On my ST4 this wire was Green White The wire from the Neutral Switch has to be connected to the _ Blue Black BBk wire on the wiring harness side This pictures shows one half of the side stand safety switch connector This is the wiring harness side of the connector actually tapped into the wire on the other side of the connector took this picture to show the wire that is really important Af
11. say There is a level of satisfaction that get when I work with my hands and when build things It is hard to explain that feeling unless you enjoy doing the same type of thing You know it is like telling someone how much fun it is to ride a Motorcycle Unless they have tried it they will not fully understand what you are talking about My dog likes to stick his head out of the window of the car at 65 MPH When wind joggles his lips like a flag in the wind he looks like he is laughing hard and is having hell of a great time His ears are pushed to the back of his head by the wind tell my wife he knows why like riding Other people have tried other solutions i e grinding down the tab close to the side stand mounting bolt that allows the rider to start the engine on the side stand But that solution will not kill the engine if the bike is put into gear am getting old and think of safety issues in my old days especially if it related to my motorcycle With the Mission goal in hand and copy of a note from the Tech Tip section of Ducati Index went shopping The only money really needed was the left over change in my pocket Here is why Parts Needed To rewire the side stand safety switch needed the following parts 1 One Silicon Diode 1N4001 50V 1A MICROMINI SILICON DIODFS 2 1N4001 A purchased these from RadioShack for 0 59 The package included two but I only needed one for the rewiring
12. ter made the connection to this wire wrapped the wires in electrical tape and was ready for testing The moment of truth 1 put the bike in Neutral with the side stand down and pressed the start button The bike started right up Yes 2 then kicked the side stand up the bike stayed on Yes Yes 3 put the side stand down and with much anticipation pulled the clutch in and put the bike in gear The engine died sigh of relief Yes Yes Yes 4 put the bike back in neutral started the bike up and kicked the side stand up then put the bike in gear and the engine stayed on It was Time for a beer There is nothing better than getting it right the first time It was now time to go back up to the PC and document what the heck did before forgot the details also thought about some of the safety issues when was contemplating doing this project After originally posted revision 1 0 of the write up one of the ST2_Owner members also posted a question regarding the possibility of the side stand switch failure and possibility of getting stranded somewhere decided to add my thoughts on some of the safety and getting stranded on the road issues into this revision of the write up A What if something happens to the wire or the diode a failure you might say The wiring and the diode can fail in two ways A1 If they fail causing the bypass wire to be open the bike will behave exactly as it does in the
