Well, just ran a ground direct from the battery to the metal frame of the dash. no luck. Guess I need to find where the harness goes to ground under the dash somewhere, but that's going to take a while...
Brent,
You need to find a place on the dash where the ground connects, that why I suggested the lighter. Just connecting to the dash don't get it.
And after that, the desert camo paint job...
Well, followed the negative lead off the battery to where it had a bolt to the chassis. Pulled it, cleaned it, reconnected, etc...
I hook up the voltmeter to the positive pole on the batter and went around checking the chassis. Got good volt readings every where in the engine compartment and under the dash.
Am I not checking things in the right way?
If I were to run a separate ground, where should I connect it? The fuse block has only positive polarity on everything right?
Very confusing.
Took it for a test drive and other than sweating like crazy, the truck runs smooth. I have to take it in for a smog check tomorrow, so I think it should make it the 25 miles to town and back.
After that I'm willing to take apart the whole dash if I have to in order to get this fixed...
Took it in for the smog check on Friday. I was 1.2 % too high on CO to pass
.
Thinking about taking part of the dash off to be able to actually look for the main ground.
Well, I gave up. Will take it to a garage on Monday and let them deal with it.
I ran an extra ground from the batter to the firewall, no difference.
I'm pretty sure there's a good ground everywhere.
Checked the fusible links, checked the positive wire on the battery.
I figure I'll let the pro's handle this from here on out. I'm out of my depth on it.
Did you try testing a direct connection to the battery and touching the ground of the dash to see if possibly the positive was bad coming to the dash?
Typically the positive goes to a power block under the hood then another cable feeds the fuse box under/in the dash. It's possible that one of those connections are needing cleaned or you've got a bad cable.
