Altenator problems

[gsxeclipse97]

While we are on subject on altenators, my battery light is on. I just replaced it yesterday and it is still on. The people at firestone said there is something wrong with my car because it has gone through two of them in a year. Now i'm wondering if my car is drawing to much power. it has 3 gauges and a switch that controlls the cyclone itm. Now is it possible that there is something killing it. I know that the factory altenator puts out 75 amps, the people at fire stone don't know the power out put of theirs

how old is your battery? check the battey it can be shorted, and i would check wiring also from battery to altnator.

Pull the Alternator and take it to your local Autozone. They can test it to see if it's any good or not.

I, too, have been having problems for the past 2 years with a small power draw with the vehicle not running. And more recently, it's becoming a greater draw. It turned out that my alternator was defective/failed and was causing a parasitic draw on the electrical system. I can't even remember how many Optima's I've killed by now....

It's definitely worth the effort to uninstall it and have it tested though.

The battery is brand new so thats not the issuse. I tried to take off the altenator today but it take a little more time than i thought. so i will continue tomorrow morning.

2g turbo alternator (alt) removal:

All nuts/bolts are 12mm so get a 12mm socket w/rachet, a 2" and 12" extension, and 12mm box end wrench. Disconnect negative battery terminal. Remove inner splash shield from under car next to alt and oil filter cooler (so there is room to pull bottom alt mounting bolt out). Remove fan in front of alt to give more clearance for it’s removal. Pull out alt electrical connector while pressing locking tab (wiggle and press and pull hard). Undo nut that holds large electrical cable onto alt and remove cable (this is hot so tape wire up so it will not touch anything and don't let wrench touch metal - in case battery gets reconnected before its back on). Remove upper adjustor locking bolt that holds alt to brace and loosen tensioner screw (see pic below). If you can now push alt back enough to remove belt off it’s pulley, do so. Remove alt bottom mounting bolt nut (just above oil filter - remove filter if need to). Drive out lower alt mounting bolt (that you just took nut off). Remove alt drive belt off pulley if haven't yet. Remove alt by wriggling it back and forth a lot while pulling hard. Bring alt out bottom (Note: Can bring alt out top but power steering pump and bracket has to be removed first). Pic below shows alt with tensioner (power steering pump and it's bracket have been removed).

So turns out that its not putting low voltage. So firestone is going to replace it for free since its under warranty.

Thats the best thing to do, if u read the forums it seems like theres a lot of cars that around every six months have to replace them because theres is not a good quality reman alt for our cars so have fun, there are a couple ways ppl have found to solve the problem just search it on here it explains it pretty well.
