Factory Gauge Panel maintenance

Hey guys,

I just pulled the gauge panel out of my 1971 Plymouth scamp so I could see why my speedometer wasn’t working. The cable spins freely and the mechanism on the gauge panel works. Perhaps the cable wasn’t clicked all the way in.

Anyway, while the gauge panel is out, I wanted to change my gauge lighting to LED as well as clean up the contacts for the gauge panel. I’ve also noticed my fuel gauge works, however there are times where it will show empty until I hit a bump or tap the dash in the right place (sounds like a loose connection of some kind).

What other beneficial work should I perform on the gauge panel before I reinstall it?

Also, the ammeter is already bypassed, and I have a separate temperature gauge so the factory one is not utilized.

Thanks!
