Is there a way you can check for ground continuity between the black and something that should be grounded (maybe the ground side of the battery connection)? White is likely the hot wire. I should have a couple in a few days and can do more checking for you at that time.

With DC black is typically ground and red is hot. With AC black AND red are hot.

That is a great idea. Its good to be familiar with using that port. I highly recommend everyone poke around in the test points when exercising their machines.

I can see that. I do appreciate that connector. It makes quick work of narrowing down the location of a problem if you use it correctly.

I would say to check the injectors and pumps and do a compression test.

I removed the under development from the file since I've not gotten any more feedback on errors.

The drawing restoration thread is here - https://www.steelsoldiers.com/showthread.php?159693-MEP-Drawing-restoration&p=1933214&viewfull=1#post1933214 This one is much easier to read than the ones in the TM.

Yep. they are marked in triangles on the wiring diagram. Download the one I worked on. Its much easier to read.

The governor module acting up is a common problem on this generator. The consensus at this point is due to moisture getting into the POTs. You can try to dry it out using the warm oven method described in another thread. The other alternative is to buy the digital controller from the forum...

I've not seen a scanner personally. I've only seen them referenced in the TM. The pins on the port are identified on the control schematic. Even without a scanner the diagnostic port is a great place to do troubleshooting with a VOM or test light.

I have the Genius G7200. It works well on 12v and 24v applications.

That is just crappy right there.

You'll need to install an autostart controller on the generator to handle the startup sequence. You should be able to buy one and make it work. Looking at the startup sequence the computer is not required to interact with to start the unit. You just have to let it boot up before starting. This...

If you have a single phase capable machine you should run it in single phase mode and wire everything up normally. It will have a neutral. The 3 phase generators is what you can split up to run two hots and a neutral to your house loads and the remaining hot and a neutral to garage loads. Both...

Residential power is split phase (center tapped single phase). Industrial power is 3 phase. Residential has two load conductors each 180 degrees out of phase with each other (plus a neutral) Industrial power has 3 load conductors each 120 degrees out of phase with each other. It can have a...

I agree. The bargains in this market are gone. I've managed to have nice examples of several units that I had considered selling but after looking at the cost to buy the next round I'll most likely keep these to help friends and family.

If you are using the generator on a regular basis to power equipment in your shop then fuel rotation should not be a problem so long as you are not storing too much fuel. Even if you do store a lot there are procedures for dealing with it. If your usage hours is modest, meaning a hundred or...

There is no single phase conversion for the 805. It is a 10 wire head. You can convert a MEP005 but not a MEP805. You are stuck with 3 phase out of that machine.

All the 8xx series generators 15kw and up are 10 wire heads.

To give you a more direct answer, it is challenging if not next to impossible to get co-gen approval for a residential install. The MEPs do not have the correct type of speed control or voltage regulator to make them suitable for parallel operation with a utility (or each other - except for...
