Alternator amps?

[larson]

hey guys what's the factory output for the stock alternator? The range is pretty wide when I look up my options on autozones website as to wich one to select.
My truck is a 1992 5speed trans. bare bones as far as options go everything is manual no power options.

I think 65-75. Doesn't matter. I would get the largest they have that is in your style case. My 88 has a 120 on it, according to the rebuild sticker on the case (was on there when we bought the truck)

Is you's a serpentine truck, or v-belt truck? looking for my 88 which is a v-belt truck, it looks like the difference in the listings is the clocking of the connectors.

Looks like the serpentine truck is 130 amps.......

My truck is serpentine.

If this is related to your other thread about the gauge, I would not worry about it. If you are, take the alternator in and have them test it.
