I think it was just my transformer's time to go actually. With all the single phase conversions out there working in this configuration it doesn't seem so important to the regulator. Actual current testing as you indicated would be valuable for data collection; however, mine is working now and I...

As stated in my earlier post, and confirmed today, I moved the X8HH wire back to T8 and moved the X9J wire to T7. With this setup 208 volts is supplied to the regulator via P13 pins L and M to the primary of T2. Someone should back me up on this, but if you wire it like this it should reduce...

I have to look back at my notes for the actual wire numbers. I moved one of the wires back to T8, then moved a wire from T9 over to T7. This way the power to the regulator is across two 120 volt phases that are 120 degrees apart, electrically speaking, which yields 208 volts. To the best of my...

Ok, here is another update. I bought a replacement regulator from Delk's Surplus in Asheville, NC. I moved the wires on the voltage reconnection board and verified that 208 volts are going to the regulator, fired it up and it works great! Had to send the old one back to them so I won't be...

Actually, if you look closely at the voltage reconnection board you will see that T8 and T9 will always be 208 volts, in either configuration. This is actually a good design! I'm surprised!

I am using the TM5-6115-465-34 manual and the figure (TM5-6115-465-34/5-30(1))does not look exactly the same as the one you used. With that being said the burned up transformer in the attached figure is item 29. In the schematic it would be T2. Per the wiring diagram it was originally wired...

OK, another update. Turns out the single phase mod was the issue. When the buss bar from terminals 10, 11, 12, and 13 is cut and rerouted the supply voltage to the transformer is reduced from 208 vac to 120 vac. This is what kills the transformer. In order for the mod to work in my case I...

Thanks for the help. And I would be interested in buying a regulator if you could spare it.

I don't think it is the mod. When I run the gen and hold the switch for field flash the voltage to the transformer is a nominal 120 vac. I hope it was just its time to go. Would you have the specs for the transformer? What is the output voltage and volt-amp rating?

OK, here is an update. I found transformer T2 in the static exciter (regulator?) assembly A11 had blown forth its guts! I see that the power for this transformer is directly from the voltage connection board Terminals T8 and T9. As I said before, I did the single phase conversion per the...

Hello all, I am new to this websiteand I wanted to say it has been a wealth of info so far. I recently purchased an MEP 005A. After cutting off the lunette ring (coudn't get it out) I welded a piece of 3" square tubing under it and installed a titan hydraulic brake actuator. Works great...
