Marker Lights, one minute fine the next dark

[TRIPLE-GREEN]

A month or two ago I replaced my marker lights with a set of NOS ones I picked up on ebay. I should add that my last ones worked great but where just tired and cracked. Once I installed the new lenses only one out of 4 work. I am a little low tech right now, so I have no way to test. But I wondered if I am missing something before I start buying tools and really going at it. Anyone had this problem before? Again they worked fine seconds before I changed them over. I checked the bulbs, all are in great shape.

THANKS!!

Did you just replace the len's?

There shouldn't be a problem then.     If you have the same old bulb, and same old socket.. It has to be a grounding issue.

The '72+ models get their ground trough the harness so I doubt that anything you did effected incoming power, but when removing the rubber sockets I could see them being deformed causing poor contact with the bulb. I would remove the sockets from the lens & with the lights on twist the socket in the opposite directions, pick up some new bulbs anyway as the action may have broken the filaments & their cheep, maybe spray some contact cleaner in the socket to eliminate dirt or corrosion. If they still won't work use a multimeter probe to see that you are getting power.

Sounds like a ground problem

I will try this today and see if it helps. That sound like it might just be the issue.
