one wire alternator

You can have a working amp guage. You just have to run the full charging circuit through the ammeter but thats what you do with the old style alternator anyway.

Yes and no with the 135 externally regulated alternator. It doesnt matter if its a one wire or externally regulated alternator to your wiring. With a 135 amp alternator you are only going to build 135 amps if you are under full alternator load though. Thats almost never going to happen unless you are charging a fully dead battery with your accesories all on, auxiliary fog lights, big bass stereo at full volume and the cigarette lighter all going at the same time. Your alternator is only going to put out what is required off it in other words. 135 amps is a lot of power! I'd still have a 40 amp circuit breaker in the line to the ammeter if you are using one.

I have a big 5 inch moroso racing pulley on mine.Its on there more for the depth of the pulley so I dont throw belts than the width as the last motor it was on saw 8000 rpm sometimes. I dont start charging until around 1800 rpm. Ive never had a problem charging with that setup.
