I've burned up 5 alternators and I dont know why. the wiring seems but but the volt gauge on the dash reads almost at 18 volts.
any idea as to what could cause this?

What car? Is your 87 camaro an LS1 swap?
If so sounds like something maybe wired incorrectly..:dunno:
More info needed...
Oh and Welcome to LS1.com..
Agree, more info is needed.
Are you running a sound system? Does your sound system have a multiple batteries to it?
Is the voltage regulator getting replaced with the alt? Are the alts used? Re-manufactured? Brand new?
yea its swapped, 87 camaro with a 99 camaro ls1 drivetrain. The wiring is fine i cant find any issues there, the alt turn on wire reads 10.2 volts like it should...im stumped on this one. i went through 3 remans and 2 new alts. no sound system except for a sony head unit and 2 speakers.
Check engine grounds and chassis grounds for corrosion or missing.There may be high resistance in system..
so all i found online anywhere says that wire should only get 5 volts...so why the hell is mine getting 10.2 volts?
Do you have a 470ohm resister in the small red wire?
no i used the whole 4th gen harness and i was told i wouldnt need it, if i do i'll put one in if that will fix the problemQuote:

pulled from a 99 ss
Check your starter. Could be pulling too much voltage.
How many wires on voltage regulator plug??
how could the starter be doing that when its only used to start the car?
it only has 1 wire in the plug
I think the L terminal should have 12 volts from the PCM. Maybe you have a bad PCMQuote:

The L terminal must be a resistance circuit eather through a charge indicator or the PCM. If direct battery voltage is applied to the generator at the L terminal, the regulator will eventually be destroyed,causing repeat failure.
AGAIN, check all engine grounds and B+ connections on alternator completly through to the battery for corrision and make sure they are tight.
Oops yep your right. I found that info in the service manual also.Quote:

i've checked all the power and ground wires, they are all tight and not corroded. i traced the red wire back to the PCM and its fine. The PCM is model number 12200411. this is really blowing my mind
