Alternator upgrade

[lcfman]

My 77 camper special C20's alternator just went out. I think it is the original one but not sure. What amp alternator would have come on this truck originally? I want to upgrade the alternator as I have added an electric fan, vintage air and an upgraded stereo so I am sure I need more charging power. Any comment appreciated,

For a stock style alternator, a 12si is a good upgrade from the 10si. 94amp and is available at most part stores. Tell them it's for an 84 Camaro z28 with a 305.

These are made in America and individually tested for output. They put out better power at idle than stock type alternators.

Not too sure but isn't the cs130/cs144 a big upgrade for older trucks?

Mine is crap stock cs130, but the HD version(According to Autozone).

Rated at 105 Amps(I know it's not true to that), but an upgrade over the 60s and 90 amp ones.

Peaked my interest.

You likely have a CS110.

I'd go to an AD244. You'll find them in most new HD trucks. They have a larger case but the bolt holes line up. If the large case AS244 simply won't fit, an AD230 will fill the bill.

The adapter harness can be had here:

Does anyone know what amp rating alternator came on a 77 C20 camper special originally?

Probably around 63 amps.
