MEP004A Voltage Regulator/Exciter BBQ

The other thing I wanted to ask you gentlemen is should I be running another fuse and bringing all three a/c lines to the new regulator? I’m planning on using this unit in its original configuration for three phase 208vac to power some hydraulic elevator equipment. I’m sure the regulator will work with two incoming a/c signals, but would it be better to connect all 3?

A third fuse / 3rd phase is not really necessary for the following reasons:

The ADVR 054 is a single phase Regulator

Terminals A and C are used for Voltage monitoring / regulation

Terminals B and C are used for the actual High Voltage Supply to power the ADVR

It is more important that the two phases terminate on Terminal B and C, as they draw the highest current and the jumper will then supply the phase connected to B to A as well via a Jumper.

The two Terminals B are connected on the circuit board directly

Copy that, and thank you once again. What an amazing resource this site is with the support and experience from members like yourself! I’ll update as soon I get finished up. Hopefully this evening.

If I read my TM correctly it should be TB 14 with D 13A connected to it

When in doubt, look at the MEP-005A TM. Some of the TM's are very old and copied too often, they are hard to read. BE ADVISED, the 15 & 30 KW TM's are very well known for having mistakes in the Schematics.

Guy ( @Guyfang ), thanks, I checked here as well after the question was posted. Most people never bother looking at them, even when they got the doors open.
Never found a mistake on those so far

I THINK, that on the MEP-003A has one mistake. And I know that the MEP-002A had some mistakes, but it always depends on when the Data plates were made. The plates from the gen sets produced at the end of their life cycle were by far the most up to date. the 15,30 and 60 KW's by and large had good plates. I once shamelessly took the plates off an MEP-115A, (400 hertz) that we were sending back to the States for testing at the schoolhouse. Taking the books out into the generator shed, was stupid, even in daylight. Taking out the schematics out of the TM was stupid. Putting the schematics in plastic was stupid. Nothing worked well. But the plates were a much better idea. And the schoolhouse? They knew everything better then us anyway! 😂

Below the picture of the Inflight HAWK Missile Mechanic. is a partial picture of our generator building. No lights and opening or closing the door invited you having the door fall off the rails and kill you.
