Yesterday I installed the new generator and now It doesn't produce any

and DF wires. So of course my red light comes on when I reconnect the
wires to it.

Did you ground DF when checking the voltage? You have to ground DF to check the generator output. [ and don't let it go to high rpm for more than a moment, when measuring this way, things get warm. ] So if you didn't you won't get a reading.

When both wires are connected, you should be able to
measure the regulated voltage at those two poles.
just like measuring at the battery.

So would you say this new/rebuilt generator is no good also?

Do you have a copy of the bentley? the instructions for checking things there are pretty straightforward. [ although there are extra more complicated procedures. involving an ammeter. ]

Jim Adney's generator FAQ, is a simpler very straight
forward version of the tests to run. I'll send you
that in a private email.
