Alternator type on a '76 - upgrade?

What type of alternator came in the 76' Argosy HMs? 65AMP? 100 AMP?

I think thinking seriously about upgrading to a 100AMP alternator. But I don't know what's in MH now.

Maybe this one:

On the '78 Argosy MH I owned, the alternator was a standard 60 to 65 amp one, similar to most all of the GM cars and trucks of that era. (I know there were some larger, but most had the 60 amp range ones).

I would not use the one wire alternator you show for two reasons.

1. It will not compensate for the voltage drop through the original wiring, which was always there, and gets worse with age. The standard setup does this compensation automatically.

2. If you have a battery isolator with motor and coach batteries, the one wire system will not properly charge either battery, due to the internal voltage drop of the isolator (about .5 to .7 volts) and the fact that there is no voltage compensation (see 1. above).

Look for a heavy duty alternator builder such as this.

I replaced my burnt out alternator last year with a 220 amp unit from www.powerbastards.com. Also got the 0 gauge wire and fuse kit for the higher output alternator. I'm very pleased with the purchase and assistance from them. Call him for the correct alternator for your setup. I also got a 240 amp isolator from another company, powerbastard's price was way too high on that part.

isolator

What setup do you guys recommend? I need to re-do the entire battery setup. When I got the MH it was rigged badly.

I have 2 12V batteries. I'm thinking I will need to replace 1 (the house) with a deep cycle type. The guy put some cheap small regular battery in there.

I don't know anything yet about battery isolators. I will research. What band/model do you guys recommend?

I thought the existing alternator was a 1 wire unit?

Thanks for the help and confusing me.
