Hi all,
Recently found low mileage totally stock c3.

Parking light turns on rear brake light.
Switching on turns on headlight but rear tail light doesn't work, tach and speedo don't light up.
Also, hazard switch doesn't work but turn signals are fine.

I have looked at wiring diagram and tried cleaning connectors at major junctions in headlight and for rear tail light. Not sure what to go chasing at this point. I do have a pigtail tester and ohm tester. Just wondering if someone has experienced similar issue.

The harness is untouched and the headlight was converted to h4 bulb at some point.
Thanks
Bruce

Check your grounds. I have found out most electrical problems can be solved that way. The hazard thing sounds like the switch in my humble opinion
