Evening all, Patient is a 72 Kombi, standard 1600 and usual wiring, etc. The electrics have been good since I got the car a few years ago. For the past 2 years it hasn't been driven much - car club events only. Last outing I switched the headlights on and within 10 seconds got smoke coming out under the dash, also a lovely burning-plastic smell. I switched the lights off and proceeded as normal. I have since found that I still have parking / headlights but no dashboard lights (until then I thought all lights were gone). I've looked under there briefly and whilst I can't get in a good position to see much, I couldn't see anything obvious. Today I changed out the switch for another one, thinking the switch is probably at fault. After doing this, surprise, I had smoke and that lovely smell again. I've pulled that switch back out. On the switch I removed, the only thing I could note is that I believe that terminal 58b could be looking a bit blacker than when I connected it all up, and the plastic around that terminal also looked a bit different, ie probably on its way to melting. I could not see any other signs of problems. I can't find any wires that show signs of melting. It would be handy to be able to remove the cluster, but I haven't done this before. I think the levers for the vents would stop me removing it. I will guess that terminal 58b on the switch is probably for the dash lights, but I don't know why suddenly it would want to melt....twice...in 2 different switch bodies. Does that mean that suddenly there is too much power going to that circuit? Nothing has been changed in the car to warrant this. All ideas appreciated, thanks!
