I'm going to have several electrical questions. 1st, Is pin #8, on the 14 pin plug at the relay board, the only switched 12v+ source in the engine compartment? TIA, Kent

I have found on my Audi conversion the ECU likes to see an exact impedance from a relay. As an example, the stock main relay is 30 Ohms. A Bosch relay is 15 Ohms. I have to run 2 relays in series to match the impedance (30 Ohms). If not the ECU will see a fault. If your neutral switch is connected to the ECU in any way, the same could be happening. It would be unusual for this switch to directly connect to the ECU but it may be the case.
Using an Ohm meter you should verify the switch is completely isolated from any other circuit. If it is isolated, the effect you describe should not happen. So you may have a wiring fault. |
