Ducie54 Posted August 25, 2016 Report Share Posted August 25, 2016 Is it normal for the Battery voltage to be displayed a little different from the power supply to the 3 pins into the ECU. Its out by .20 volts. AUX 9/10 and 17-20 match the voltage at the fuse when i checked pin 5 Plug A it was the [email protected] voltsĀ Quote Link to comment Share on other sites More sharing options...
Scott Posted August 26, 2016 Report Share Posted August 26, 2016 Hi,Yes this is fairly typical of what you would see. The battery voltage goes through some components in the ECU, so I expect some voltage drop.Scott. Ducie54 1 Quote Link to comment Share on other sites More sharing options...
