No power getting to my left rear marker light when I turn on my lights. Bulb ok. Any test points suggestions?

Any chance you have the service tech manual ??

Can you follow the wire back a ways to a connector ?

Just bought this used. No tech manual.

Test the contact points in the bulb socket with a DMM, if you don't get any voltage reading, try a different ground point. If you get voltage, the fixture had a bad ground, if you don't get voltage, you need to chase the wiring upstream to find the fault. It'll probably be in a loom, so check pinch points and where it goes through panels and might get abraded.

Already checked out ok as suggested. Just wondering if someone had similar situation. If it was short to ground I believe fuse would be blown. I'm thinking open somewhere. No manual, open to suggested test points.
