I figured it was about there. Yep, the days of under $1k MEPs is gone. After the hits from the hurricanes last year, seems like 50% to 200% more people are bidding on these.

This is fine tuning time on this machine. It is still a couple of days for diodes to arrive along with varistor. One final check and look over before the full 8 hour load test. Got to find a door though. In the mean time I am going to make a replacement as best I can. Got to find a break...

Yeah I got it. AC 2.5 to 3.0 across 3 and 6 of the relay switch. I found it in the manual. I usually do not do things unless I am absolutely sure of the process. So I adjusted the mag pickup to 2.6VAC and locked in place. Pinion gear now disengages properly.

I put varying loads on the genset for 3 hours. Put 40% then 65% then 85% loads on it. All ran OK with no issues. There is something that I noticed today but it came home this way. I do not think the motional transducer is operating properly. The starter pinion gear is not disengaging when...

You are right about the skyrocketing prices of these units. Sorry I stepped on your toes on the bidding. What did you pay for your one out of Albany? On this one, I got lucky.......

Take a look at the butcher soldering job. It was butchered. Leads were cut and resoldered and the solder joints are questionable. The varisror was 67 cents and the diodes 54 cents each. Yes I will replace them. Sometimes even if it works, it has to be fixed or tweaked. Replacement of these...

Well, today I replaced the fuse holder for the alternator. Checked it over once again and gave her a shot. She turned over a bit then caught and fired right up. Let it run for awhile then decided to check the output terminals to see if there was anything and all is OK here as well, as I...

More: Looks really clean except for that disaster at the burden resistors. As I said, I opened the back of the generator today and did the depot testing on the generator itself to determine if there is something that may have caused this issue with the diodes. Here are the results...

Pictures of inside the set. Also better pictures of the burden resistors and diodes.

Took the cover off and examined everything including the burnt electronics smell (there was none) and found this to be the only thing that appears to be out of order (not normal looking). So it appears that the 2 diodes and the varistor may be bad. The varistor is red colored. This is a very...

My thoughts too. Need to start diagnosing the problems. Considering these are all generator related, I need to check all the generator leads before I even attempt a start.

I have a feeling that there are at least the diodes and the varistor are going to have to be replaced. Have to find the cause first... Looks like someone put the heat to these. Have a feeling that the genset or the generator part at least may have some damaged components.

Any particular reason that these can not also be used. I am not an electronics component expert, heck I can barely not confuse diodes and capacitors and transistors except that they are round, flat, and tubular, sometimes...... https://www.mouser.com/ProductDetail/71-RE70G7R50...

Can someone explain to me what the resistor diode assembly in the control section of the genset do? I saw a genset that may have bad resistors and diodes, discolored and an ashy substance on them. What do they control/what function do they serve in which circuits?
