Thread: 1 wire alternator

Tweet

As many good schematics and drawings as he's put up for me, I should probably send him a check!!!!!

I have a 1-wire alternator on my project '34. I understand that some folks have had problems with 1-wire alternators, but this one is new, and I'm not inclined to throw it away. I just don't want to burn the project down.

The attached diagram shows how I have it wired.

All the outputs from the panel are fused, based on what they're attached to. If any of them shorts out, the panel fuses protect me.

I'm thinking I need a maxi-fuse in wire "B" in case the alternator runs away on me. Does that make sense?

Denny,

I never had an old Chrysler . . . no clue what that is.

I put a maxi-fuse on all the cars I build!!! Cheap insurance for an electrical fire!!

Dave,

Did you put it where I indicated?

how do i know how many amps my alternator is.. my dad bought it for me a while back and i never asked.. cus i have mine setup the same way henry has his ran but without the panel?? And what exactly is that panel for?? And wat exactly is a maxi fuse.. sorry im new to this stuff guys im just a suspension guy wanting to learn more.

The "panel" is the main fuse box in the car. That's where almost all of the wiring originates. A maxi fuse is a very large capacity fuse (60 amp or more) that protects the main supply circuit in case of a major short.

Denny,

It's 80 amps.

Painless has the optional one wire kit and a 50 amp maxi-fuse in most all of their kits as I understand it. This should prevent any battery explosions or fires. They were in my basic 12 circuit kit and I wired my Powermaster for 1 wire operation.

The only downside I see with the 1 wire is you do have to get to some rpm before it switches on. Once it's on it latches in and doesn't turn off until you turn off the car. I ain't too worried about a little blip of the throttle to latch it in.

Hmmmm. Didn't know they stayed on, thanks Kitz. So the low rpm no charge problem isn't really a problem as long as the engine is once over 1500 rpm and not shut off????

I believe that is correct ............
