Thanks Guys, received. It doesn't matter how big I blow it up though I cant see a way that the neutral light comes on when key is in park position. I can deal with the other power lost, its a logical fault find - but how does a 12v condition get to the park position 30 seconds after it was running just fine. I switched the ignition module - still showing neutral light in park, cant see other possible connection point.
so anyway, thanks guys, I will start tracing the wires and testing the components.
Regards
Glenn
