Title: 1966 GMC 4107 Odometer issues
Post by: claretd on September 08, 2022, 11:32:43 AM
Trying to see digital odometer mileage and it intermittently goes on and off.  Any suggestions on how to fix?

check and/ or repair connections at sender first, then check connections at dash.

Not sure of your read out. In my case with similar problem it was the supply voltage as the gauge was partially powered by the sending generator when the supply voltage was bad.

Where is sender or sending generator located?

sender is usually connected on driveshaft end of transmission, although in a few cases, a pickup comes off left front wheel. (uncommon)
