Help with Alternator
|
Thunder279 Unregistered guest | Alright, I have a 1996 GMC Jimmy with a stock alternator. I have 2 Rockford Amps pushing at total about 1500 watts and I sorta killed my altnerator. I also have a 1.7 farad capacitor. Now I have called many alternator shops and they pretty much refuse to put in a 160 amp altnerator because There will be nothing but problems. I dont know why.... So I guess my question is, is it really that unsafe to put in a large alternator like that? |

All you're doing is adding a device that will give you more power. If those guys can't handle that then they shouldn't be in car business. Now for alternators, try 4alterstart.com. They will be more than happy to help you. Since you own a "normal" American made car, you should be able to buy the alternator at a good price. For 1500W, I'd try 170A - 200A. Don't forget to buy the new 4gauge alternator wire too. You'll need it with that much current. Oh BTW, GMC Jimmy has plent of space under the hood for a bigger alternator. In fact, you should be able to replace it yourself. Very easy too do. You can then laugh at your alternator shops being morons. You can buy a car book that'll show you exactly how to change alternators in Jimmy for $10! |

Thunder279 Unregistered guest | Hahaha, thats funny. Out of the 10 shops i've called in my area, 5 wont even look at it and the others will do it, but they wont offer me any warranty on it. Im like wtf! They say that the bigger alternators don't recharge at idle, but i mean really who cares. |

(the alternator that is, not the car) Anyway alot of cars come straight out of the factory with setups that don't/barely charge at an idle. LOL Get an alternator and change it yourself. Easy to do and rewarding as you did it yourself. Cheers Glenn |

I can't believe there are car audio shops that don't do alternators, or at least recognize the need for them. That's like having a hospital that doesn't think a pharmacy is useful.. |
