This. You want to verify you can press here and compress the spring and it springs back when you let off pressure. It's a strong spring. Looking at other pics on the web of the IP yours looks like it might be stuck in the compressed position.

That explains why it was stuck! Obviously, someone removed the pump trying to fix an issue and caused another one. While you had the pump out did you verify you could compress the plunger on the pump to verify it wasn't stuck? The pumps in 802's and 803's will get gummed up and stick compressed...

To see how it fits together you need to look at the engine specific TM 9-2815-257-24P The black arm is bolted to "P/O 23". P/O 23 is attached to the end of the shaft of 23. The top of 23 has a "U" shaped cup in the top if it. The metering pumps fuel control pin sits on the "U". As 23 swings...

Thx for the reply and video. So there appears to be two issues. 1) I suspect the magnet strength is set too high not allowing the actuator to lift off the magnet. Low starting battery voltage could cause this too. 2) Most importantly and why it's not starting is the black arm (throttle) that...

I've tried to recondition two Concode batteries. At first, they seemed to recover but both quickly died. I replaced them with pairs of new 12 V AGM's in both sets. They work great. I don't see anything wrong in the pictures posted. Minor issue is someone removed the locking factory safety...

The relay for that is located on the board just under the top cover of the Inverter. The one circled in red. The whacky Governor Control is due to either the Governor Controller being out of adjustment or more likely the Governor Controller is failing. The adjustment procedure is in the -13&P TM

You could. Just don't forget to remove it should it ever be switched back to 120/240.

OK.... Could be 1 of the inverters has an issue. I'd suggest setting it to 120/240. The apply a 1,500 watt load from L0 to L1 and see if the inverter half can support the load. Disconnect that load and reconnect it from L0 to L2 and again see if the inverter half can support the load.

What mode is the inverter set to? 120 or 120/240? If 120/240 is your load balanced? L0 to L1 and L0 to L2? Is it a 240 volt load (L1 to L2) or two 120 volt loads L0 to L1 and L0 to L2)? In 120/240 mode if either load is greater than 1,500 watts the Overload will occur. Remember, the...

I use the BD681G components when I repair them. ---> DigiKey BD681G

4" here and winding down. Had to hang the plow on the truck and clear the driveway and parking area.

I cut the package open and slipped the nut and bolt in a small Zip Loc bag. Will drop it off at the post office Monday.

Nice to meet you too. If you like I can put that nut and bolt in your package with the replacement GC.

Are you Steve K.?

About 1.5" of snow here and still coming down. Deer foraging for food behind our house this morning

FYI - 114250-66440 is Yanmar's part number for the bolt and is not the NSN number for it. The actual NSN number is: 5306-01-431-7459 Info about MEP part numbers and NSN numbers can be looked up at Parttarget.com That bolt is a Yanmar unique M6 bolt with a hole in the head for the locking wire...

The AC output is pretty clean on a MEP. Here are a few oscilloscope waveforms for comparison. Ideal 60 Hz power waveform Typical utility power waveform (at my house) MEP-802A power waveform at 50% Load

Which model alternator do you have? 8EM3005CA or 8MR3005CA? Per the TM... 8EM3005CA 101-206 ..SEMICONDUCTOR DEVIC 1 0142499T36 ..SEMICONDUCTOR DEVIC 1 8MR3005CA 101-193 ..DIODE,NEGATIVE 1 101-235 ..DIODE,POSITIVE 1 101-130 ..DIODE,TRIO 1 From a Prestolite parts matrix 8MR3005CA alternator

I see you only have 111 hours on it (if it's accurate) 1) Have you checked fuse FU1 to be sure it's good? 2) Have you verified that the Exciter terminal on the alternator is getting 24 volts when S1 in in Prime/Run? Failures I've seen in the alternators are: - Failure of diode(s) on the diode...

The diagram I posted is a cleaned up version that @DieselAddict created and I augmented with more into. Only the bottom contacts in S5 change position when S5 is lifted and only the top contacts change position when S5 in pushed down.
