I'm no expert, but the light socket grounds against the housing. When you pull it out it interrupts the circuit, hence volts=0. Check that the socket is getting good ground as you are reinstalling as they can get bent.

The power to the blinkers usually go thru the flasher to make them blink. However, I am not sure if a flasher is bad do you get a light continuous or a "no light" condition.

The parking light bulb is dual filament. One is parking, the other is blinker. They are separate circuits.

I'm just not sure how to better ground it. The housing appears to be plastic, so I'm not sure where I'd run an additional ground. I could try grounding at the rear where the housing is metal though. Think that might work?

Take a look at the other side to see what is different, since it works properly (right?). Maybe that will help.

If you're talking about the turn signal/park light in the front bumper, the housing should be metal. It grounds through its attachment point to the bumper (the bumper is grounded to the frame).

There are no turn signals in this front bumper. It's custom. I'm talking about the turn signals in the side markers on the front. Those appear to be plastic housings.

They are plastic. There should be a ground wire coming out of the front lighting harness that grounds to the core support by the voltage regulator.

Okay, I'll take a look for that. Thanks all for the assist!
