Thank you! Electrics, even on my low-mileage car, had itched me quite a bit...
That is: - engine temp gauge "jiggles" a bit when around 80C
- my blower vents (I don't have A/C) blew one of them cold, the other hot air(both wheel set on minimum temp)
- fuel gauge "jiggled" a bit sometimes, then went back to normal
Please, tell more on how this main ground can be found. Is it a cable-type or a metal-mesh-strap type?
~Thanks
