1. Battery Positive Battery positive is supplied to the PDM via the single pin connector to suit wire sizes 16 mm 6 or 25 mm 4 The PDM16 and PDM32 use an Autosport connector PDM15 and PDM30 use a 6 mm eyelet to suit the wire size The wire gauge should be chosen according to the wire temperature limit and acceptable voltage drop Tefzel wire must not exceed 150 C The temperature of the wire is affected by the ambient temperature air circulation current wire gauge the temperature of any surrounding wires and the covering sheath See Wire Specification and Connectors and Pinout for details Battery Isolator Switch Battery positive must generally be connected via an isolator switch or relay The isolator must isolate the battery from all devices in the vehicle including the PDM starter motor and alternator The isolator must be rated to handle the starter motor current When the battery is isolated the engine may continue to run due to power supplied by the alternator To avoid this the isolator switch should have a secondary switch that is connected to a shutdown input on the ECU MoTeC Installation 5 If the ECU does not have a shutdown input the switch can be connected to a PDM input The PDM can then turn off power to the ignition system or the ECU which will cause the engine to stop Battery Negative Both of the Batt pins should2.

Many electronic devices will have a short inrush current The PDM will largely ignore this due to the Output Load filtering See the Over Current Shutdown section for details The PDM provides reverse battery protection and load dump clamping to protect itself and the connected devices Ignition Systems Inductive Ignition Systems Most inductive ignition systems draw a peak current of about 8 ampere some draw as much as 20 ampere however the average current is much lower In most cases inductive ignition systems can be connected to an 8 Amp output however the Output Load current must be checked to ensure it stays well clear of 100 The average current will increase with increasing RPM so the Output Load should be checked at maximum RPM CDI Ignition Systems CDI ignition systems can draw peak currents of as much as 50 ampere It is recommended that all CDI ignition systems are connected to a 20 Amp output The average current will increase with increasing RPM so the Output Load should be checked at maximum RPM Engine Management Systems The current drawn by an engine management system will depend on the type of loads it is connected to and the operating conditions Fuel injectors draw current in pulses The maximum average current drawn by the fuel injectors is when they are at maximum duty cycle For servo devices such as Drive by Wire motors maximum current is drawn when making large transitions Check that the Output Lo
