Question Ground Wire Mystery

While disassembling the interior I found that a wire has been added that is screwed to the metal cluster housing (not the flex circuit) on one end and grounded(?) to where the column bolts to the dash on the other end. This is a heavy gauge piece (12 ga.) that is clearly not original equipment. I'm completely stumped why this was added. Is this some sort of fix for a known problem? Any guesses? All opinions welcome. Thanks!

Re: Ground Wire Mystery

The previous owner(?) probably had problems with the ground strap on the high beam indicator so they just added that wire in place. I'm not sure of exactly how it goes togther, but the high beam indicator (if it still has it's ground strap) goes together in a certain order to allow contact with the metal for ground. I know some people on here know the way the high beam light assembles.

EDIT: What year is this? (my suggestion is for a first gen. 67-68-69)

Re: Ground Wire Mystery

assuming your talking 67-68, the high beam indicator red lens has to be the first thing on. If it's between any of the metal pieces, your guage cluster won't ground.

Re: Ground Wire Mystery

About a year ago I picked up a 1968 GM service bulletin binder on e-bay. It includes the service bulletins, monthly service news, training booklets and other information. There is a service bullitin for the ground wire in question. Apparently early vehicles were experiencing problems with the fuel gauge and with the dash lights due to a poor ground circuit. The additional ground wire was installed to insure a good ground circuit. Hope this helps, RonM.

Thumbs up Re: Ground Wire Mystery

It's a 68. Excellent input from all of you. I'll plan to reinstall this wire during reassembly. Thank you!
