Will another vehicles alternator fit my 00 trooper??

[plex_love]

I have 2 sundowns sa 15s pushed by a 1500 watt audiopipe....didnt bother upgrading anything because it didnt seem like it was pulling that much power, my lights never dimmed or anything. Well tonight i was driving home and the bass hit and my cd player kicked off and my lights went dim, after that it satyed that way for the last minute of my drive, when i hit my brakes the lights dimmed, so im about 99% positive i fried my alt. Problem is i cant find one for a 2000 trooper that is over 90amps!

Does anyone know if there is another vehicle alternator that would fit on it? if so is there anywhere special to get it?

Your best bet would be to buy an aftermarket HO alt from one of the leading companies. However if your trying to keep down on cost you can take your stock alt to a local shop and have them install a higher amperage regulator. Usually you can have them install something like a 110-130A regulator without having to change any of the internals and it costs like $50

what good would a bigger regulator do?

the stators create the current. the regulator just makes sure that you're not charging at 19v.

The regulator will feed more current into the windings during drops in the system due to system demands. That means if you drop in an upgraded regulator in the alt it will allow more current to flow to the field coils which induces a greater voltage in the armature coils thus bringing the output voltage back up to normal much quicker and with greater ease on the system (14.4V when charging). The more current allowed into the armature of the alt the more power can be produced. Now the armature does have a big deal with this, they too have a max current that can be produced. So most times factory alts can be seen using something from a 90A-120A regulator in the same housings using the same stators and diodes, just different regulators. Now if Im wrong I will gladly admit it.
