Burned up 3 alternators, does anyone know if there is a 1wire alternator that will mount in the ls truck bracket. I'm using an 02 camaro 411 pcm. The 5.3 motor and harness is from an 02 tahoe. The alternators i've been trying are for an 02 tahoe. Wondering if there was a 90 something truck alternator that was 1 wire like my 87 k5 and would mount in the lsx bracket
The old alt will fit...or at least I've seen them mounted before so I can't say for sure if modification is needed.
My original alternator from my 1992 truck was a one wire.Not sure if it will mount in the LS truck bracket but i will take a look when i get home.
Thanks. I got measurement last night. Bolt holes are 140 mm apart. Gonna ask the guys at auto zone to pull a couple from the mid 90s tonight and see if i get lucky. Let me know what you find out.
My 2000 rcsb has a 1 wire setup
The bracket setup is different.You might be able to make it work.The bolt holes on the 92 are 5 1/4 inches apart.
if you're buying them from vatozone, no wonder they aren't lasting.
Agreed lol my brand new $89 eBay altenator has proven to be the most reliable so far (compared to vatozone)Quote:

Not for sure, but this is probably why i was burning up alternators, too much voltage on this wire. some pcms have two wires, another going to R75 and pin "C".
