Help with Gauges

[carlyneedham97]

I have a 77 k10 that I'm in the process of restoring. Im having issues with the gauges. When I turn the key on, the p/s turn indicator illuminates and stays lit. All bulbs are working properly. When I turn on the hazards, all of the back lit bulbs for the cluster begin to blink. Does anyone know the locations of grounds for the gauges besides the ones on the radiator support??

You can ground them anywhere that is metal.. infact you should probably add a few extras I know we did on my corvette.

Thank you [emoji849] I'm looking for the ground wires from the cluster and if/ where they may ground other than the headlight harness

I may be way off, but I had a bad ground up above my hood latch pull in the cab, way up there under the dash high in the kick panel area. Chased that for a bit.

Be sure and check the little ground clips inside all the light sockets to make sure they are in tact. We just figured this out this morning on our 85 project and it cured all our problems. We had a socket with a broken ground clip

I don't think its a gauge cluster ground issue. Its a ground at one of the 4 turn signals. Every time I have had a turn signal indicator light come on steady like that its a bad ground at one of the lights. And the back lighting could be blinking because its back feeding through the parking light circuit.

Is there a ground wire screwed to the frame at each turn signal? I don’t recall seeing one on my trucks.

The ground for the cluster is a single black ground wire connected to a post near the top of the emergency brake assembly. If its missing or loose the gauges will "find" ground through various other sources.
