Unless you have a short that's killing the alternator, then you shouldn't have to repeatedly replace them. Batteries, yes, an overnight draw may kill a battery, but not the alternator. Are you goin with "chain store" rebuilds? Kragen, Pep Boys, etc? If so, you may wish to try taking your alternator to a real rebuilder and having it done right. Those chain store rebuilds consist of the absolute minimum parts required to make the alternator generate current again. Of course, you may have an electrical short that's wiping them both out, but that's not nearly as common an occurrence.

Do you have an aftermarket stero in your car? (Just throwing something else out there)

yeah i have an aftermarket stereo. a 300watt amp pushing 150rms and then a sony deck 52watt*4 and then the sub is just a 10. well i had a friend that gave me an alternator pulled and tested that came from an 88 but i don't think that it is charging the battery anymore.

You sure your amps are wired properly?

i.didnt.do.it

Thats what I was thinking...somethings draining the battery, could be the amps...



Has the system been installed longer than this has been happening?

cezonetheillest

yeah i am pretty sure that the amp is installed correctly. i have disconnected it for now. also i had them for about 1 month before all of this started to happen.

ColinRX7

You need to be 100% sure.

cezonetheillest

well for now i have the amp disconnected but i also have a wire that i checked with a voltmeter that was also pulling like 12.5v and it looked like it was a chopped wire, it was black then went to a white connector and the it looked like it was white/red(or yellow/red) something like that. so i have no clue where it goes though.

I would suggest you take the car to a mechanic

who does electrical troubleshooting, for what you have

paid for 4/5 alternators and batteries you could have

the problem fixed by now. Someone who knows what they are

doing should be able to figure out what circuit is shorting out in

no time, then with your permission they could pinpoint the exact culprit.



A RX7 is no different then any other car when it comes to shorts

cezonetheillest

no i also remember taking off the rear window tint and i messed up the defroster things. would that do anything. that was the last thing that i did before i had this problem.(well other than an oil change)
