Thanks Charlie, it may take me longer, but I am persistent....

Glad this mystery is solved!

Good call Yun, you can say that again.....another one for the books....as they say....

Just as a precaution to anyone getting a rebuilt unit from any supplier, check out everything before the install. Even if it means undoing the pulley to make sure that the correct washer and spacer is there, otherwise use your parts off of the unit you are replacing.

So what alternator do you purchase for the LT5. Is it a standard vette item that just needs to be reclocked for our application, or from another vehicle entirely?

Well the 200 amp unit I purchased was off of ebay and listed as a ZR-1 unit.
I am almost sure this is the one that Dynomite listed awhile ago in one of his threads. Will look up the info....
The way it came through it was clocked wrong as stated, other than that, it is the same.
It may be that the ZR-1 unit is different from the standard Vette unit, I am not really sure. And don't know if there is another vehicle application that will fit ours. Maybe someone could add to this!!!

Update.....this is the 200amp unit I purchased awhile ago and it does show that it will fit either the base or ZR-1
only thing is the pulley is to small for us, you will have to use your old pulley on this unit or the pulley from Summit that was also mentioned in Dynomite's thread....and most likely re-clock the housing, which is no biggie.

Bought a 200 amp off e-bay did the same thing. After the fix the alternator lasted about 2 months. Put the original alternator back in/

Frank, was it purchased from the same seller as the link above?
What happened after 2 months, did you ever check it out further as to the reason why??

GOLDCYLON · 01-31-2017

Yep that's were I got mine. Got a month out of it and then it failed

Was yours also the 200 amp unit?
Because if that's the case, I'll take mine apart and rebuilt it, rather than use this replacement. That's two failures, you and Frank, not good. Don't feel like doing this again for a long time....live and learn!!!

Added questions for both of you regarding the failure?

1-did you determine what caused the failure?
2-did you change the pulley to the correct size pulley?

Because if you used the pulley that came with the unit, which is much smaller, that would surely lead to early failure....thanks for any additional info....

FU · 02-01-2017

I didn't see this thread till the other day. We bought the same alternator from the same company. Mine was bought 4+ years ago. Long story short...After it was taken apart to put the spacer in the alt. it was also discovered that the pulley was the wrong one for the ZR1. That's how they get the amp rating up by putting a smaller pulley on the alt. By then the original unit was rebuilt by instructions from Dynomite and it was decided to install the original unit back..
The 200 amp alt. was used for a door stop until Sandy got it.
