Hi people, Quite awhile ago I had posted a question that my temp and oil pressure gauges were running real high almost pegged, and the speedo was jumping. Someone suggested a grounding problem in the dash. When I went to check it everything worked ok till this week. I notice when you put a load on such as lights or the heater blower, the two gauges even go higher.
Where should I start looking for loose grounds? Or is there anything else I should check?

 

Sounds like the return of bad grounds. I would do what you did before, chances are it will work again. Use some dielectric grease on them, it may delay the return for a while...Mark

 

There are 2 ground wires close to Ash tray area by the steering column check them and then also check the wire on the firewall that is on back side by Number 6 cyl.

 

Look at the fuse box as well, and see if there's any melting going on.
