Ground issue revisited

[RobertRN]

Hi,
Got a fairly simple question for any experts of knowledge in the GM electrical ground issue.

I am thinking of taking a wire from every ground site on the engine, body, frame,and any others and of course clean the sites well,and also running a wire from each site up to a main ground block/bus that I would attach to the driver firewall and then run a big ground to the alternator bracket and also the battery to hopefully get rid of any demons now and in the future.

Would this cause any other issues combining all the grounds to one spot?

I have a 04 Yukon XL SLT 2500 2 WD with the 6.0. it is getting at that age where I clean them up but it seems like one is always playing tricks on me. I'm thinking doing this is redundancy but will give me more life out of the grounds.

I think you'd be better off doing just the "big 3" wiring upgrade. Adding all the grounds you suggest might cause ground loops.

Check out the "Big 3" ground upgrade. Large capacity cabling from batt neg to Alt/Eng, Frame (straight down) and Body (at firewall). This will typically take care of electrical gremlins. The single common point should always be batt neg, to eliminate potential for ground loops.

Ground loops. Google it.
