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?
Hey Thunder279, you need to find a better mechanics. It's not rocket science. 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!
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.
yeah - gotta say - WTF, if they are that concerned about that then they could just change the pully and belt so that the damn thing is dong higher RPM at idle. (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.
you'll rarely find any warranties offered on modifying an engine of a car to non factory specs. that's common. try www.4alterstart.com they can do just about anything. 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..
can anyone tell me where the R and F terminals on my altenator go, I have been reading , but I must be missing something , I could use a simple diagram or text on how to do this. I am putting a corvette motor in a ford truck, and I am doing all new wiring , thank you .glen
