good job...about buying a fish...... Buy a man a plane ticket and he flies for a day,
push a man out of an airplane and he'll fly for the rest of his life.
I deleted my previous post in regarding not having the resistor installed in my alternator. My 10SI alternator kit arrived yesterday and included the resistor. Upon disassembly, my unit did not. Did not know if it was required or omitted by a previous alternator rebuild. I found on a Delco Remy service document that not all 10SI models required the resistor. Then, looking at the GM Service Manual, there was a photo of the 10SI alternator without the resistor, plus an adjacent wiring diagram showing the same. So now that I got that question resolved, today I will take the alternator to a shop to have the bearings installed and hopefully tomorrow I'll have the alternator installed and ready to go.
Also had to buy two torque wrenches to cover the torque mounting requirements from the assembly manual...should have bought the fish!
Here is the not needed resistor...would like to place it on eBay for a buy-it-now price of $420 to break even on the above project!
Sell all the tools, and go out in your Vette for a nice fish dinner.
The alternator shop installed the new bearings while I waited...a fifteen minute job with the right tools. So below is the photo of the two alternator halves ready for assembly.
It looks like a 94 amp stator to me. 78 amp minimum. If you can measure the stator wire size, I can tell you what amp it is. If you can tell me what the numbers stamped on the rotor are I can tell you what amp alternator it is for. The main purpose for the resistor is to light the charge indicator light in the event of an open rotor which seldom happens. If anyone has a one wire alternator you should leave the resistor out. The trio does more than supply power to balance the voltage in the light circuit causing the light to go out when charging. It also supplies power to the field to keep it charging.

Unfortunately, I have the alternator mounted on the engine. Just waiting for my torque wrenches to arrive so that I can make the final torque adjustments. Does post 16 photos of the stator give you a clue?
All the stator pics give clues. The wire looks to be pretty heavy and not a lot of turns for each pole. That would make it a higher amp stator. The laminations are from a 12SI alternator most of which were higher amp than the 10SI which is what you have. At this point none of this matters as long as the light goes out and it charges. If you want to know how high the amperage is drive it to the alternator shop and ask them to test it to see what the output is. I think you will be fine with it since it worked before.
Took the C3 to AutoZone for a charging system check. Alternator failed voltage test with system loaded at idle. My idle rpm is 600. At 800 rpm, the alternator carried the load producing 14V. Will bump up the idle slightly.
Not unusual at that low of RPM . How often are you at idle with full load anyway? Probably not enough to worry about. You could use a smaller pulley on the alternator, but an idle bump would be easier. Good luck
