1982 AQ125A alternator question

[steve242002]

Hey guys, I have a AQ125A with a bad alternator. Sitting on my shelf I have a motorcraft 130 amp that is real close to fitting minus a little modding. Is there anyway that I can get this to work woth my engine? The regulator on the existing says its 14 volt but the motorcraft says 12 volt.......any thoughts?

any thoughts?

Take it to a repair shop and have it rebuilt.

The replacement alternator must be marine rated. Is it?


An alternator "rebuild" is often nothing more than a brush replacement. See if you can get brushes for the alternator you have. They are usually easy to change.

I agree with mischief. It will run you about $ 25 bucks for a rebuild. Besides the one you have is what they call an alternater ignition driven. Its somewhat different.

The problem is the dumb_ _ _ that I bought the boat from let the bilge fill up with water and everything external on the engine was solid rust, i've rebuilt the thing from ground up but now need a new alternator and starter. I doubt they can be rebuilt, I had a 3' cheater bar on it and it wouldn't move at all. I was just hopeing that I could use my shelved unit instead, and no, im sre it's not marine rated.

Re: 1982 AQ125A alternator question

You want both of those electrical parts to be marine rated, as they are supposed to be built to resist/supress sparking. Always a bad thing in a closed environment.

I would start with Ebay, Iboats, Boatfix. Doug Russell is thorough, but expensive.

Pardon my ignorance, but what is a "alternater ignition driven" alternator? Is that a 1 wire, two wire or three wire? Is there anyway I can test it?

I dont think they were that expensive to rebuild. These are a Paris Rhone ( something like that) altenator. I had altenatorts rebuilt that had bad bearings, frozen solid and worked great after rebuild. Also had starters full of rust rebuilt that turned out fine. Best u can do is take it to a shop and have them check it out. Or shell out the 800 bucks for a new one. Your call...


A good shop should replace the bearing and any other wear items in a rebuild.

I took my alternator to a shop today and he said it would cost more to rebuild it then it waout to by a replacement. He quoted me 249 for a comparable one, marine of course, 60 amps though. On the flip side, He has a replacement starter (marine) with more power then the original and it's only149.99.

Thats a pretty fair price, the 149.99 prie. You can contact the folks at DB electrical and see what they got.

If i remember right and some one let me know if im wrong, volvo used a couple different altenators on the 125a engine and one have a bigger belt, i remember ordering an altenator belt for mine and the marina asked what sized altenator is on my boat. Guess the more powerful one had a bigger pulley.
