1992 Panda CLX
Apologies for long post - I wanted to cover what I have investigated so far...
A couple of weeks ago the panda started fine, but when I turned the headlights on, the dash light went off, and rear window heater light, fuel light, fog light light all lit up dimly and the indicators didn't work.
I have read Dragon Man's thread about commonly occurring faults and other threads about weird electrical behaviour.
I have attached a jump lead from the engine to the bodywork and the fault persists. (I already have an additional earth running from the battery to the bodywork) The hedgehogs look fine and everything seems properly connected
My problem seemed to be similar to the fault on the thread: (https://www.fiatforum.com/panda-classic/418420-earth-fault.html) which traces a fault to the ignition. So I checked the connector blocks under cowling and then swapped the ignition barrel for the old one I replaced in Sept '18 (The barrel was fine, one of the door locks had broken). The fault still persisted. I didn't check for connections coming from the ignition barrel housing (I couldn't feel any)
Whilst I was putting everything back together, I discovered the horn only works when the key is out of the ignition, but when in the ignition and turned 2 stages the horn doesn't work but all the gauges max out and all the coloured lights light up while pressed.
So I was thinking maybe it could be the ignition barrel or the connectors coming directly from it(?) What would I be looking for behind the ignition barrel electrical connections-wise?
Also I was wondering of any of the recent work done on the car would have caused it to suddenly have a earth problem. Recently a core plug has been replaced and the coolant replaced, and the oil and filter changed.
Any advice on how to rule out the ignition barrel connections or any other sources of issues would be very gratefully received. It would be good to be able to drive in the dark again (and toot the horn)
Many thanks
