No left front park light.

[davischevy]

I'm working on a 72 that has no left front park light.

I have what appears to be a ground problem.

The LF signal will work until I turn on the park lights.

The park lamp won't light, but has power, just not enough to light the lamp.

The same goes for the LF side marker. Power but not enough to light the lamp. It does blink with the park lights off and the blinker on.

Anybody run into this problem before.

I'm sure it's a ground, but can't figure out where. I hooked another steering column to the truck with a known good signal switch with no change in symptoms.
