This winter I bought a MEP 005a with 2hrs on the runtime meter that had been put in a mothballed condition. Getting it up and running was simple. I put about 10 hours on it, and now it's giving me fits. I had an overvoltage condition (270V) that I couldn't figure out. So I bought a rebuilt voltage regulator. I hooked it up - 0V. Swapped the old one back in to see what was going on - 300V and rising. So I put the rebuilder back in, and it gave me 220V but didn't respond to my rheostat. Eventually it drifted to 240V, but like to shed the load and go back to 0V. I checked the field - F1 to F2 show resistance within norms. And then I went to replace the rotating diodes because the voltage regulator rebuilder certainly thinks it can't be his box. I completely spaced and put in 6 1190 RA diodes and didn't pay attention to polarity. So I need help with two things: 1. Can someone help me figure out which slots should take the forward and reverse stud diodes. 2. Any ideas other than voltage regulator or rotating diodes for my no output issue? I've checked all 6 diodes that I remove and they all show between 0.43 and 0.51 V drop across them.
