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

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.

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!

I’m k I’m back at n here looking at this. The terminal strip on made the A5 is going to be difficult to access. I’m I looking at the diagram correctly thinking that wire D118 will n the A11 J9 connector is the same wire? Looks like it is going thru R35 and then to the J9 connector. Can I intercept the wire there for simplicity?

Wait a minute, I think I do see it at the relay board terminal. Right here.

You can use the wire D11B which terminates on Pin C of P9
This would leave R35 in the circuit but that should give you still enough voltage for excitation
guessing a terminal number is never a good idea. If you want to connect to A5 TB14 then make 100% sure that you are on A5 TB14
otherwise you may experience fireworks beyond your wildest imagination

I was going to write about the same thing. And the A5 card is not sooooo hard to get at. Anyplace else involves hacking the wire harness. Not my first choice.

Yes, I was mistaken. It is pretty easy to to access actually. A much better option than hacking into the harness. I was looking in the wrong place initially. Thanks.

Yes, I thought that the description was quite funny.
Arc-flash events seem to be quite memorable to me, and your description had me holding my sides with laughter as I thought that it was such an amusing understatement.
Keep up the great work @peapvp!
All the best,

I sure wish I had have had that gear on when I had my day in the "SUN"!

Alright quick update on this thing. I got busy with the kids sports but I was able to finish the install enough for a test. It’s producing power. Sorry to disappoint you fellas but no fireworks. Couple minor issues, first, the wire from terminal 14 in the A5 produces 27 volts dc but it won’t carry any current. When I connect that to the completed circuit it will read voltage to the incoming side of the resistor but nothing to the other side. When I disconnect that wire and jump it to the d/c breaker the excitation gets going and the output is working. Now the main breaker isnt closing with the switch so I need to get into that. I had it working before so it’s something intermittent there. I suppose I can just revert back to the field flash button on had already installed but I’m m puzzled as to why the terminal 14 won’t work now.

The K5 relay gets only power when S2 start run stop switch is held in start AND S9-1 Normally Open Contact closes at app 300rpm
If K5 doesn’t activate then you may have a problem with your S9-1 Speed switch

Yes, that makes a lot of sense. I do believe the s9 switch is having some issues. I notice that I’m getting an intermittent issue with the start switch as well. I see on drawings the s9 contact that feeds the K3 relay. I jumped 24v to the k3 relay and the starter engaged. I had the whole A5 box out and traced the circuit thru cr3 everything checked out ok. When the starter engage switch, I believe S2 fails to engage the k3 relay, all I do is bump the engine with a jumper at the starter solenoid a couple times then the S2 switch comes back to life. This leads me back to the S9 switch as well. I’ll be studying up on the s9 switch in the TM and hopefully find some more good info here somewhere. If anyone can lead me to a good troubleshooting and repair thread for the S 9 switch that would probably save me a lot of time. Thanks in advance.
