Ground straps, Make me angry Options

[emerygt350]

Brand new ground strap, installed clean and brushed on both transmission and body. Completely failed me. Wire brushed the neg to body. Checked the cables and replaced the post to starter cable (it was questionable ). Car still wouldn't turn over. Added a new 6 gauge cable from the negative terminal to the spot where the coil attaches to the tin work, turns over like a new car. Even my gauges are working better. Wth. Could it just be the transmission case itself?

I remember an argument about additional ground straps a couple years ago, but can't find it. Any reason not to just keep my aftermarket ground strap?

Corrosion where? I put a brand new strap on when I rebuilt the engine last year. Cleaned everything when the engine was out... Maybe the 50 year old metal (what's left on my car) just can't take it?

Measure where it’s at. I keep posting how to do this but no one takes it seriously.

Stop guessing

If you’re unclear on how to do this I’ll gladly help.

I was measuring and it all looks good till you hit the key. My eyes glaze over when superhawk starts writing about all the ways you measure load. I had my Porsche guy use his magic amp measuring device. Not like I was throwing parts at it, just pissed a brand new strap on perfectly clean points didn't work for more than a year. And it's parked all salt season, so seriously, in the air apparently.

Another interesting outcome: I updated to all LED lights and my fog lamps (not led) kept on working. After I fixed the ground today... No more fog lamps.

You cannot measure the resistance. Hundredths of an ohm matter.

Please read link. Have to measure voltage drop while cranking.

"while cranking" is the key phrase here. When everything is at rest or near rest, the current path works, add a real load and (IMG:style_emoticons/default/WTF.gif)
