Grounds - Useful Information
Please add to this thread for ground connections but in my experience with GM vehicle, the grounds should be:
I had to add one between my cluster and firewall because of the usual cluster lighting issues many have. A simple check to see if you have a ground problem (slow crank when hot for example): Take a set of battery cables (which you were going to ask for a jump start for the slow crank issue anyways) and do this:

Here is an older thread, It spans quite a few years (2010-2018) but it covers just about everything. https://67-72chevytrucks.com/vboard/...d.php?t=422234 Really shouldn't have to add a ground to the cluster if the original one is there and it is making good contact. Most of the time a bad ground to the cluster is because the cab isn't grounded correctly. LockDoc |

We're working on some really old iron. Any connection made at the factory is suspect, even if someone did a frame-off, because corrosion waits for no one. (Rust never sleeps" :P ) My temp gauge went south, probably from corrosion. I'm thinking about replacing the whole instrument panel with custom gauges, to eliminate that printed circuit board which is certain to be corroded, based on what else I've seen in the cab. This on a truck that lives in the "irrigated desert" in southern California.

I have added extra grounds to all my old vehicles. Just good preventive maintenance to do it as said with older vehicles.:chevy:

I remade all my grounds when the box was off a while back. Probably overkill but I have access to great bonding materials where I work.

Looks like that braid is made by 3M: http://m.3m.com/wps/portal/3M/en_US/...294469250&rt=d

I recently added a ground strap from my cluster to the firewall and inside the engine compartment, from the firewall to the block. Going to add yet another but haven't decided exactly what location yet. As had been said, grounds can't be trusted on vehicles this old and they are generally neglected. Sufficient grounding improves a great many things and increases the life of components.

Re: Grounds - Useful Information
I have a ground going from the underside corner of the rear bumper to the sheet metal across from it.

Re: Grounds - Useful Information
Glad you guys found something still being made out there! I still use the smaller brade from the back of both heads to the firewall. The big braid is great for chassis grounds.
