Diode Air Conditioning Clutch
 

Does anyone know what type of diode to use on the AC clutch coil?

I have 1N4004 diode but I think that for an 89.
Anything for LT5?

If not I'll give 1N4004a shot.

That should work as well for the LT5.. compressors and clutches are basically the same, LT5 compressor volume is smaller but i would not think that would be an issue

A diode across a coil is there to absorb a surge when the magnetics release. It's not like it's a constant current thing. That diode should be fine.

LT5 clutch is different than the standard. It is unique due to the higher RPM I believe.

When I bought my Z, the belt was shredded. I put a new belt on and within a week, it was shredded also. I looked through all the receipts that came with the car, and found where the a/c clutch had been replaced. I referenced the pn and it was for the LT1. I showed this to the dealer, and he replaced the clutch with the correct one for free, even though it was the previous owner who had it replaced.

I've seen this TSB by FourSeasons regarding the diode you mention but the TSB references the RS part number for that diode part #. RS # 276-1103 is their number for the # you referenced. Does it mean squat? Don't know.
