Car Forum / Driving, Maintenance, Tuning / RVs / December 2007One wire altenator
If anyone is having charging problems with an older RV, they make a one wire alternator that can be used on any engine with a 12 volt system. You just mount the alternator and run one wire to the positive terminal of the battery and you are done. This could save someone a whole bunch of problems and money.

I was thinking that GM made a single wire in the 70's, maybe not.

He complained of hard starting and smoke from "somewhere" Maybe 200 amps were going thur that small wire from the block to the firewall.. That's also where the smoke was coming from (for some strange reason)...K I've seen a few clutch cables fried because someone hooked a new cable to the frame. s Once worked on a neighbor kid's car where someone had the battery ground connected to the frame of the car.

Chevy/Workhorse used a braided copper cable to make the engine to chassis connection. My observation was on a 2001 18000 lb chassis. The cable looked intact until I tugged on it. It litterally crumbled in my hand. Don't ask about the embarrasing circumstances that led to that discovery. http://www.alternatorparts.com/what_is_a_self_exciting_alternator.htm
