Headlight issue

[TAPR]

The left headlight is not working on my 76. The high beam will work but low beam out. Tailights, dash and side markers all work. Checked the light itself, and both high and low beam work. Checked the ground at the headlight bucket as well. Cleaned the tailiamp grounds, and am getting current at the fuse and the fuse is okay. Running out of places to check. Any help would be greatly appreciated. Thanks.

Have you checked for volts going to the lamp? If no volts, check all wiring connectors in that circuit and then the column switch.

No voltage at the headlamp on the lowbeam wire. High beam okay. I'll check the column switch next
