You can ground your cable to the body if moving battery to trunk. Then you just have to remember to ground the motor to the chassis with a 4 gauge or better wire. I personally cannot see an advantege to running that long of a wire to the block when metal is a great conductor(the body frame etc)
Mine is grounded to the body and I have a Volkswagon type braided ground strap from the chassis to the block. Works just fine.
I ran the wire. Your probably right but I feel better this way. I'd rather high current travel through the wire than the body.
Hmmm...lot of discussion for a simple subject. To run a one-wire alternator you do only have to run one wire. Odds are that your engine already has a ground wire ran to it unless you're just building the car and haven't grounded it yet. Your engine does have to be grounded to the body to make everything work correctly. The starter won't work if the engine isn't grounded to the body. Therefore, if you want to use a one-wire alternator...just hook up the one wire and go.
yes Stephen I had it tested, its working fine. I am goig to up it to a 100 amp this winter, I was just a little "wondering" after I read the article.
By the way, '70, I went to PA-Performance site and looked at the alternator they have for a Mav. They list it as an oversized case and that is a problem for a factory a/c car like my 4 door. There's no room to modify anything as the problem is the a/c compressor and the frame, not the brackets. Can't do much about them. I appreciate the info, but I'm going to call Performance Distributors in Memphis (901-396-5782) about the one in Mustangs & Fords. It doesn't look oversized. I hope I'm right about that because it's a bit hard to tell from the pix in the mag, but it looks real close to the one they removed.
I went with the larger case from PA-Performance but they do offer a smaller case version. Worth the free phone call to ask. Allan
I'll just do that. I already got stuck with one alternator that I have no use for because it didn't fit like I hoped. Just don't want to get stuck with two.
