Been looking at these wiring diagrams and when i get to the resistors and transisitors on the VR ASSY GEN section from wire P67 coming from Bridge Assy im lost. Also Pin 6 on the bridge assembly shows P55 then follow it to the right it turns into P59? This is getting confusing fast

Put a new resistor on it. Connected meter leads and it briefly showed 22 volts across it then went down to 3-5mV. I had 221 volts on taps L1 - L3 and 110 volts on L1-L0. Everything seemed fine so turned generator off and let it sit. Hooked leads back to the resistor and it showed 21.5 volts...

So I left that resistor on the board and have used the generator several times as power goes out often. No issues till today. Went out to crank the generator to let it warm up. Its main breaker was off and no wires attached to the taps. Checked the oil and fired it up. After about 2 minutes I...

I had a friend give me a 75 gallon tank off one of his wrecked dump trucks. It fit my generator trailer and was clean inside so built a frame to hold it and have it plumbed to the AUX pump. Works great!

Thank you for the clarification on that. I've done alot of wiring and stuff on race cars but never dealt with anything like this so I'm learning. But what your saying is that the resistor is only used during the engine starting process where this DC power is applied to the fields to excite...

Now i just have to find out how to permanently attach it to the board. I just used some wire to rig it and wanted to test it before going through all that trouble of soldering it to the board and the problem be else were.

My MEP-003 changes tones a little when the well pump kicks on. The MEP-002 really changes tones and has a little puff of exhaust smoke when the well pump turns on.

This is the resistor that i ordered. https://www.digikey.com/en/products/detail/ohmite/HS25-56R-J/5307759?s=N4IgTCBcDaIBIGUwFZkDYBKApAtAOQBEQBdAXyA My dad was telling me to measure the Diodes and to get one the same size or larger if it was bad. So once i get all those tested ill see how...

Thank you GuyFang. I'm learning as I go. I now see the fine print as to the last 2 digits are wire size. I'll double check the P59G. It's hard to make out on the wiring and the diagram. I haven't opened your PDF yet tho. I found some wire wound 56 ohm resistors and ordered the minimum of...

This is the best match to replace the resistor. https://www.digikey.com/en/products/detail/ohmite/HS25-56R-J/5307759 Im wondering if i can solder that resistor on the board so i can trouble shoot it better?

Thanks Thats another of my problems is finding legible schematic. I emailed Mr Jim yesterday to see if he made a board for that. He replied no and I needed to find out why the resistor blew before replacing it.

MEP-003A Plate says to use TM 5-6115-585-12 I have a R1 Resistor Failure on the Bridge Rectifier board. Im looking at the wiring and i see the burnt resistor is attached to Location 5 and 6 on this board. In the TM i find that 5 = P67A16 wire and 6 = P59G16. P67A16 goes to A2 and im lost...

Wow I didn't know Ida made it all the way up there. Not yet. Was gonna watch my other thread tonight and then post up tomorrow a new one looking for the part.

Not yet. You in Louisiana?

I wish it was that easy. The resistor on the bridge rectifier assembly released its smoke.... :(

Got to love a forum like this! Thanks for the help. I'll keep eye on the thread I see GMG shows one listed but out of stock.

Yea the shipping is the worst part usually but now I can't find the bridge rectifier board anywhere on the net. A buddy works for the .gov and he said they just got all new cat gensets and auctioned off all the 002 and 003s they were using.

I got a 003 last year and it's been a good one till this morning. We lost power Sunday night and still have 2+ weeks they say till we get power back. The 003 had a light blue smoke out of the exhaust when more than 50% load was applied. I knew I needed to check the oil level but I also knew...
