Oh, the current diodes are ashes. haha. So where am I taking these resistance readings? I assume across the various windings? Looking for continuity to ground?

Ok, I ordered a 'megger' insulation tester and should be able to spend some time on this in a few days. I'm going to research exactly how to do the test and what readings I'm looking for, but any tips or pointers would be greatly appreciated!

Thanks for the info! To clarify - the exciter is the same as the rotor/rotating assembly? I'll have to do some research but I' assuming if I remove the diodes again, I can take resistance reading in place of the 6 diodes and look for a dead short?

The mecc alte rep just sent this 700+ page manual. I'm hoping there's some troubleshooting flowcharts and/or various specs that I can start pouring over. I see on page 45 that it appears I did install the diodes in the correct polarity. Which makes sense because when I acquired the generator...

Mecc Alte would not give that up. They also would not give any of the specs on them, and when they arrived they showed up in a clear plastic baggie and have no markings on them aside from the band on one side. I spent a considerable amount of time trying to find diodes that did not cost $27 a...

That doesn't sound good. What's the remedy?

@Scoobyshep @kloppk - Hoping you guys have some insight for me. Installed the new AVR today (opted for the correct one, not a universal one). After install I'm back to getting 4 VAC out of the alternator, and across red to red at the AVR. However, If I try to flash the yellow/blue wire with...

Update - Still getting between 40-60 vac out of the alternator. Went back to step 1 of the troubleshooting and re-verified some steps. Red to Red at the voltage regulator is about 33 vac when running. When I try and flash the blue / yellow at the voltage regulator with a 9v battery, anything...

Update - Thanks to everyone and their suggestions. Turns out I didn't have to pull that rear bearing housing at all. I forgot the generator spins, and after remembering, I was able to bump it over and access the diodes. Spoke to the sole Mecc Alte dealer in the US. They sell a ton of these...

Right on; I appreciate it.

Yeah, as soon as I touched the DVOM probes to the diode leads, they just crumbled. Do you know how this bearing carrier comes off? Do I need to use a puller, or should it just pry off?

Yeah, after I posted I realized pictures would be helpful...haha. Thanks!

@Scoobyshep @kloppk I got distracted by some other projects, but I'm finally tearing back into this generator. This morning I removed the rear vent cover to try and find the diodes. As expected, it was tight and I had to disassemble the generator body slightly, but I'm now working wide open...

You know, you make a good point....I've got absolutely no idea what a crane would cost to lift it onto a trailer. I just assumed it was going to be astronomical. I called the yard POC who confirmed they offer zero assistance loading and I'd have to hire a crane.
