    i went to pep boys and got the alternator rebuild kit- it came with brushes, diode trio, regulator, and bearing. 13 bucks. a new 90 amp was like 120, so that was good.....

    after disassembling the alternator, it was obvious why it quit charging- the brushes were crapped out....

    the instructions made it a snap, and now it's ready to go. i would HIGHLY recommend this course of action as opposed to going to get another one........

    oh yeah, the allen head/wrench method doesen't work so well on the 86 12si flat belt alternator, but i zapped it with the impact and it came right off, hey i was replacing the bearing anyway....

    aw yeah. 90 amps. thirteen bucks.... thank you....

    Re: alternator options?

    the pulleys should be intercangable, just unbolt the big nut on the fron, and any alternator can be clocked to whatever you want, the only problem is does it mount the same? I dont know.

    beligerence doesn't justify intelligence.

    so you can increase your amp output with the rebuild? you don't have to buy one that is the same as you existing output? if that is the case couldn't a guy rebuild it to be 100 + amps?

    Re: alternator options?

    i'm sorry i shoulda clarified!!

    i had a 65 and a 90 amp unit. i rebuilt the 90 amp unit, and swapped pulleys from the 65 amp one that was on the truck to begin with.....

    any alternator shop, if you live in an area large enough to have one, should be able to rewind your alt. to crank out some extra amperage....

    greg ( ssorry for the confusion!!))

    I thought about rebulding mine originally but what I needed from that alternator were beyond typicl rebuilds. So I went on ebay and purchased a customized 190 amp alternator with a idle kicker in it and it works quite well

    OK I'll bite. What's an idle kicker? How does it work? Who makes it?

    Real trucks don't have spark plugs!

    Re: alternator options?

    190 amps???? WOW, that's a lot of juice!!!![​IMG]

    I see in your pic that your run some off-road lights, but what else does your rig have that requires that much power?? Just curious......

    Is there any risk of overloading your electrical system with an alternator that powerful?
