That does look convincing similar for negative input/positive ground, though I wonder a bit at the diagram in both places of a multi-cell battery for a 1.5V input. Learn something new every day! Thanks. All the best, 2Pbfeet

You are welcome. The learning curve at the beginning is often steep. No, I did not find it in the manual, for as @Guyfang pointed out above, the part called out there is for the entire assembly, but in general that part number and description would give you a starting point for a search, if you...

Part number 11675004 NSN 5340-01-059-0114 aka "Slave Cap Assembly" I believe. Available from many sources, you can try searching for "nato 1 pin slave receptacle cap" e.g. https://www.eriksmilitarysurplus.com/naslrecowrec.html All the best, 2Pbfeet

😯 Wow. A positively grounded battery on a modern piece of electronics seems unusual to the point where I would be wondering about a documentation error. It would certainly have me being extremely careful. If you probe the (-) point when the controller is powered up is there a voltage? I...

That is the data plate for the engine. How useful it is might be a different item. What parts are you ordering? There's ordering MEP-803A parts, there are Onan specific parts, there are Lister Petter (LPW4) model parts, and of course generic parts. The most specific is always going to be...

As @Ray70 points out I would suspect that there is something amiss with the camshaft, probably its gear. To me, the "rocker arms they seemed to be 90 degrees off" and "...there are spots when rotating the engine where it gets tight like we have interference..." are consistent, and both point to...

Nice job! Way nicer than my version. We live with fire risk most of the year, and I realize that the Jersey shore is usually wetter, but, that lower heater runs a risk of baking the ground in front of it. If it were me, I'd make sure to have it on concrete, or with the louvers pointing up. I...

@peapvp great eyes on the wire. To me, that frayed wire looks as if it is almost burned in the photo.

I understand the challenges of not having enough time, and at some point the whole "time is money" devil raises its head. Only you know what you are up for. Running the machine at slightly reduced output power may fix the compression/carbon issues, but I don't see how it would help low oil...

Seems like a very intact and generally clean unit to me. If it were me, I wouldn't be cranking to start without the fuse mod installed. Unknown history and all that. I would not be surprised is it spits some smoke and carbon as you start to load it up, as it seems as if there is a bit of black...

Do you have the manual? Have you tried the included flow chart for troubleshooting? How old is this genset? I'm not finding any reference to that model number on the PowerTech site. Did you call Powertech to ask for advice? A few photos might help, particularly of the voltage regulator and the...

Can you share a bit more information please? Model number, hours, generator head manufacturer, known servicing details, and its history, e.g. have you seen the unit deliver 20kW? All the best, 2Pbfeet

Having cats is not the same thing as zero rodents. Ask me how I know..., and I would not overlook mud dauber and paper wasps...

Kinda hard to tell from here, but the body panels seem to fit, no massive leaks, coolant looks newish, and no sign of fire, but the photos are photos of photos, so it is hard to tell. May I suggest getting your hands on it, and taking some better photos? Then doing the fuse mod and MOV if they...

I would point out that Rudolf Diesel's engine is a far cry mechanically from today's diesels. FWIW: I have switched to hydrotreated vegetable oil for my diesels. It is also called renewable diesel in some areas or HVO. It burns more cleanly that petroleum diesel, and has a better lubricity...

Here's a Bridgeport II schematic. As @peapvp points out, it looks set up to convert; http://igor.chudov.com/projects/Bridgeport-Series-II-Interact-2-CNC-Mill/07-Schematic/schematic.jpg

You've probably considered this, but why not replace the the motor, or possibly adjust the internal wiring to support 220V? 1HP is not usually an expensive motor compared to some of the possible switching solutions, unless it is an unusual rpm. A lot of the Bridgeports came 450/230V. All the...

@KD7CAO that's an impressive amount of carbon in the manifold and an impressive amount of oily/greasy unburned diesel and carbon on the piston heads. I'd start with carb cleaner. If you use compressed air, try to have it going across the top of the piston head, rather than down to minimize dust...

I believe #12 are the slide on terminals for the winding that go on terminal block 10, along with #45. If you are missing 12 as connections, the generator is going to have real trouble generating electricity. All the best, 2Pbfeet

Welcome! Congrats on getting it purring like a kitten. Which TMs do you have and have you read? The fourth photo has what looks the remains of rodent nest. If it were me, I would start by cleaning out the debris (fire and short risk), examine that area for wire damage, and clean off the mouse...
