Headlight ground

[dareguy]

I have tried cleaning all the connections between the radiator and the grill, but my left headlight is dim. I realize this is a ground issue, but I don' know where to look next .. HELP please (1972 negative ground Series III, 88")

First, have you run a voltage check? Do you know whether the circuit is at fault?

The headlight itself might be faulty. If you can swap it out owth the one on the other side, you could see if the problem is in the sealed beam.

If you know it's the ground, then try running a separate wire from the ground wire at the headlight to another location. Then you'll "solve" the ground issue.

Dim lights...

..can also mean low voltage coming in. Check those bullet connectors for tight clean connections.
