Re: '70 C10 Temp Gauge Max Hot, Why?

Had a similar thing happen once after I changed the cab on a 72 pickup.
Temp gage would go full hot when key was in the start position.
Problem went away after I installed the ground straps from engine to cab and from cab to frame.
Was the gage carrying the full ground to the cab? I don't know.
