CUCV Voltage Output @ 43v??

[83k30]

Hey guys, I have a new to me 1986 M1009 that's giving me a headscratcher...I replaced my gen1 alt today and before i hooked my red bat+ lead from the alt to the engine wiring harness block i wanted to check the voltage output at the alt while running. My voltmeter says 43 volts?? Is this because my alt is not hooked to the wiring block and not sensing a charging load? Any advice would be appreciated.

Thanks

I'm no alternator/regulator whiz, but yes, I think running the alternator open would result in overly high voltage output.
I also think that it could be a good way to cook said alternator.

Well I just got an education in alternators....open circuit is now closed and working great!

Glad to hear that it worked out, with the alternator intact and working.
