Re: alternator upgrade

[Matt Haas <mhaas@xxxxxxx>]

Ian,

You may have a Delco alternator already. I'm pretty sure AMC started using 
them in the 70's but I'm not sure when. If that's the case and it's the 
original alternator, the output rating is stamped on the body (I think it's 
near the plug in the side but I'm not 100% sure on that). 63 amps was a 
very common size but I think there is also one around 50 amps.

If you need more amps, there are plenty of aftermarket choices. If you have 
a Delco alternator, I think you can go up to 200 amps. If you have a 
Motorola, Power Master makes 100 and 140 amp units that bolt to the factory 
brackets (this was recently discussed -- in some cases slight changes to 
the brackets and/or belt lengths are needed). If you're willing to make up 
brackets, there are all sorts of choices available.

On the other hand, if you're not having problems with your battery draining 
now, you're probably okay.
