Suzuki Samurai Alternator

Postby Nvrndng » Thu Jun 29, 2017 2:24 pm

Stock alternator too big and mounts in wrong place. Suzuki Samurai Alternator came up and I bought one but don't know how to wire it. There is a three blade male connection on the alternator. I think it is 12v+, 12v+ switchable and Tach. Anybody know?

Some alternators are self exciting and need to be grounded, some need to go to the battery light on the dash with a resistor in line etc.

Best thing to do is post up a pic and we can identify which style it is.

I used a Camry Alternator on my Vega, working great! :thumbup:

Looks like a self exciting. Make sure the case is grounded somewhere good and not sure if the charge indicator light has a resistor in it or not but if you have a volt gauge keep an eye on it.

As an example I have a self exciting alternator that provides power directly to my fans which draw the largest current. As I flip on the water pump, trans fan, rad fans etc it will drop to 12v then come right back up to 14v. Some alternators have a seperate "controller" that tell it what its output should be. Without a proper ground you risk burning it up fast.

Pictures will still help

Thanks for the info. I went by the repair shop and they are going to get me one off a Cat fork lift and convert it to a single wire unit. Plus the Cat unit comes with double belt pulley. They'll have it ready next week. It weighs about half what the stock GM unit weighs. Puts out 60 amps and that should handle my truck. Thanks again.

Most alternators will self excite if you rev them up enough, but that one is excited by switched ignition, (makes it start charging sooner). The Charge lamp itself is a resistant load that will provide a ground path for the lamp if the alternator isn't charging, :wink: 8)
