Regards odd wiring problems. IIRC, Punto Mk2(a) automatics would throw a gearbox wobbly if the reversing light was faulty. Anything from switch to bulbs or earth could upset it.
What yearBefore I put this back together, any suggestions as to where there could be other earth points?
This is what I found.
1) On nearside wheel arch behind back door.
2) Nearside passenger footwear on wheel arch
3) Under battery on front main beam beside main battery ground leading to gearbox
4) Behind battery, above ABS pump on suspension tower.
5) Under plastic panel, on metal cross panel, beneath wipers.
Any more to check?
I have replaced both rear light cluster wiring connectors and cleaned all these earth contacts, but still have my lights issue.
Right it's does not appear to be obvious or common faultYa. Been measuring voltages at the bulb contacts between left (near) and right (off). Offside, seems normal, 0V at ground, 12V for dim and 12V for Heads.
Nearside is different, voltages not as expected. Bit weird to be honest.
Dims and heads came on together, more on nearside than offside.
Stripped out the body computer to check for burning etc. Nothing there, not a sign of damage.
It was suggested, as its probably a grounding issue, to ground the nearside to bypass the fault. No success, just blew a fuse.
At a bir of a loss, to be honest.
