Hi all.

I'm stumped and looking for advice please.

My reversing switch output is not registering and connecting across the switch connector terminals also gives no reverse 'on' signal. I've removed the short heat shield and the wires look intact.  The yellow and black lead is sending 12v to the switch.  I'm thinking that the next place to test is the other end of those wires but they go into a big wrap which seems to go through the bulkhead.  Can somebody with a wiring diagram or better knowledge than me please advise where I should test to get the other end of those wires. 

Thanks

Mike

Hi Mike, welcome to the forum. Try pushing a small pin through the wire insulation into the core where it exits the switch - then use that as multimeter connection. This will confirm correct operation (or not) of the switch itself. The pinhole in the insulation will tend to self-heal when you remove the pin.

Good idea. Have just tried that.  The switch its good. 

Should have clarified. The switch is good but the signal from the switch is not reaching the computer. VCDS is not showing a reverse signal from the switch. 

 

Anybody have advice on where I can get into the other end of the wiring so that I can test continuity from there back to the switch. If there is a break I can just put in my own wiring and leave the rest of the loom. (Which I think might be better than stripping it down to find and repair the break)

thanks,

Mike
