MEP005A frequency meter not working.

[yohanusmarcus]

Its in the A27, Special Relay Box

Might be an issue? Still looking for tb101.

It’s in the box next to A11 you just opened. The box with several Canon connectors on it

Looks like this when open:

This would explain why your frequency gauge is not showing anything, no voltage no frequency

Yes sir! Thats it. Take the 4 nuts that hold the A5 card in the A27 to the side wall, off. Look at the back of the A5 for burn marks.

But your A11 static exciter is also shot. The A11 will not have any influence on the fuel pumps, nor the starting and run function of the set.

Yup finally found it. There are several wires that appear to have gotten hot in the past. From J15 to Tb101-2 and one from J10 to tb102-1. Along with the burned transformer, did just buy a boat anchor?

 

[Guyfang]

What about the A5 card?

 

[yohanusmarcus]

What about the A5 card?

This is the A5 board

 

[yohanusmarcus]

I also have a second mep005 that appears to be a precise machine that has no starter or ip I was considering as a parts machine

you probably want to check the bridge rectifiers diodes and the extra diode on PCB and all resistors for ohm

So should I look for a new transformer or just the whole box

the transformer, the circuit board, the large capacitor and the six diodes mounted on heat sink
But before you buy all this, you can read this thread I wrote about rebuilding a A11 and how a A11 is bench tested before, during and after a rebuild

Repairing a A11, read all post starting with this one her #56

I have T2 transformers for sale if needed

 

[yohanusmarcus]

Thanks I'm not sure I'm up to the task but ill keep you updated.

If its a precise unit, then its not a MEP-005A. IT's a MEP-104A. Look at the data plate. Take pictures. The A11 and A27 are the same as in the MEP-005A

This is the reason you dont hear the pumps coming on. Reach out to Klopp for a new board. Then for the voltage regulator, just update it with a newer VR. Several write ups about it.

 

[Guyfang]

Before you jump to conclusions, I would also test the Day Tank Float. There is the procedure in the TM. If the float doesn't work right, then your pumps are not going to turn on.

@yohanusmarcus this would be a simpler alternative to the A11 repair after you get your generator running correctly

One possible aftermarket AVR solution for 004 005 006

This is not a MEP gen set.

I do have TM's for it.

It is a good set. But nothing on it, or better said, very little of this set, can be used on a MEP-005A.

Ok I just assumed on that one because it was part of the lot. I would appreciate the tm for it though thanks.
