Just a bit confused, the reversing light's have stopped working, as the car is a auto they are fed through a inhibitor switch for the auto transmtion. the wiring diagram shows two (2) separate switches one for the reversing lights Green and then Green and brown and the inhibitor for starting white and red wiring , but in reality all four wires go to just one switch the inhibitor switch unless there is a second switch.

Hi, Yes, It's a combination switch it does both jobs. Check its adjustment so it operates correctly. Try moving the gear lever through its whole range while someone watches the back of the car to see if the reverse light work, possibly in the the wrong place.

The power to the inhibitor is dead ( reversing light side), so the issue is further back, so If there is only one switch I'm not sure where to start

I removed the radio and the speaker but not able to find the correct cable, Green going into green and brown. So I was wondering until I do find the lost supply can I link across from the inhibitor side of the switch to the reversing light side or will it cause a problem.

Hi, No, because the inhibitor side gets power from the starter position on the ignition switch and then goes to the starter relay to trigger it. The reverse side of it has an ignition supply (Green because it's fused) and then goes to the reverse lights. You could however pick up a temporary supply from the fuse box.

thanks for the reply
I will have a look, I am a bit suspicious because the green cable coming out of the fuse box has a chock block with a red wire attached, this was fitted so as to give a 12v supply when electronic ignition was fitted a couple of years ago so possibly it has disturbed the connections I will try again to follow .

Hi, As regards that 12v supply for the electronic ignition That really needs to be on an unfused (White) wire from the ignition switch. If the fuse blows on that circuit you lose the supply to the ignition and the car grinds to a halt. Do you really want to be stuck at the side of the road trying to find what has made the fuse blow and correct it before you can continue your journey, especially if its raining?

Hi colin
 
Hi Colin
I am a paraplegic (paralyzed from the waist )so I paid a garage to convert the ignition and yes I agree with what you have said. It was only when you brought it up it was obvious about the fused system so I will get it changed. It was my son who took a picture of the connection so I could see where it came from even the I did not think about possible issues.
