Where do these grounds go?????

[chevyCowboy]

i was poking around in the engine bay today taking off the motor mounts and some other stuff when i found these grounds with brokin ground straps attached to them. can any one tell me where they go? havent looked at it yet but i know there is something in the 6.5TRL about grounds but i got to wondering if they are the same on a mechanicaly injected engine?

the one is on the frame rail and the other on the firewall had two straps on it and is just about right above the one on the frame

Don't know on the '92, '93 mechanical inj trucks.

On the '94/'95's, one strap screws onto the frame just below, the other went on one of the upper bellhousing bolt/studs towards the top on that side.

Would be logical they're trying to tie the cab, frame, & block together electrically w/ good/v low resistance connections.

On all these grounds, I cleaned all the corrosion off, put a little Kopr Shield (often used to enhance ground connection longevity in industrial wiring - see link below) btwn the connectors/surfaces & on fastener threads, then screwed it together.

After the fasteners were tightened down on the frame connections, I sprayed a little flt blk paint over them to slow corrosion around the freshly grnd/exposed steel.

The ground straps are the same on the 92-93 trucks as 94+. I went a little heavier on my 93.:thumbsup:

On my 94's the flat braided grounds come off the frame to the firewall then to the coolant blockoff plate on the passenger side head.

Bk I like what you did there, can I still your idea??????????????

I put another one of those slightly larger cables from a unused bolt hole on the front of the block to the frame were it is easy to see and not in all the heat from the exhaust. I got the cables from a farm supply store for less than $10 each. The factory flat straps had rotted off.

As mildly relates to this subject, you often see the pad where the starter bolts to painted over during rebuilds.

The bolts threading into the block usually make a good enough ground for the starter, but I've seen a couple instances where a starter was replaced thinking it was weak, that turned out to be poor grounding to the block.

good to note that ill make sure and mask that are off before i paint

All this ground stuff is good to take care of when the engine's out - so much easier to get at everything.

Would also suggest running any gauge plumbing thru the firewall now. Much easier to do a clean pass thru & get it sealed well, when you've got good access.

Making sure the right/rear glow plug wiring is tiptop is another thing far more easily done when the engine's out.
