Don't adjust the VR to get you above 208 on a two phase setup. Look at the data plates on the equipment and it will let you know if its OK to run on 208. A fair amount of equipment is rated for 208-240v.

Can you describe the scenario? Is this emergency power or prime?

Three of those are OUTPUT wires. The ones on the left going to the contactor. They don't count.

I'm super curious about this possibility since the diagram in the TM shows it as a 10 wire head. There are 12 wires coming out but two are not load conductors. They are for the VR. According to the diagram the load conductors should be T0-T9.

Yep, you guys called it 100%. One screw loose and one missing.

Have you verified its a 12 wire head? My understanding is that everything 804 and above are 10 wire heads.

If they hadn't been so far away from me I would have been bidding on them. I expect they will show up on ebay for $3k each like I've seen with others. :(

Thanks for info. I will check those for sure as I work on the repair.

I started up the 831 yesterday to charge batteries and noticed some soot coming out of the gap in the insulation wrap between the exhaust tube leaving the engine and the main muffler body. Pulled back the jacket as much as I could and noticed a crack radiating out from the welded fitting. I'll...

You are correct. Load is load. Even an imbalanced load does work so its not an efficiency problem. The diagram is a simplified version of an alternator. There will be more pole groups than is represented so the rotation distance between peaks of magnetic flux will be a lot closer together...

I fell like I should probably let you off the hook at this point. I was asking those questions to make the point that the return path doesn't matter in regards to fuel efficiency or energy waste. The engine won't be loaded any differently whether a 5kw load is split equally between L1 and L2...

Doesn't all energy that leaves the head have to return to it?

Why is energy on the neutral not performing work?

Could you expand on how an imbalanced load affects fuel efficiency?

Another option is to do a KIRK key interlock system between the main breaker and the generator breaker. The lock on the main breaker is key retaining so when its turned on the generator breaker is locked open by the same key. You would have to open the main breaker to remove the key. Take the...

I'm OK with snow but the ice we get here sucks. Thankfully the storm spared us this time and it came down as all rain. Still a chance for something tonight but lower probabilities.

Wanted to give a bit more info about my generator test. I've been using the generator lightly loaded on a new piece of property I bought earlier in the year. I've not been able to put much more than a 10% load on it for the last 30 hours of run time. Yesterday I brought it home and gave it a...

Tonight in central NC we have the potential for a bit of freezing rain. That can be a really bad time here if we get trees down on power lines this far out into the woods. Figured it was time to give the MEP803 a bit of a workout. Warmed it up and increased the load till we got it a bit over...

I'm happy to share how my setup is done. Feel free to ping me off line.

Batts be toast. You may be able to recover them some with the right charger but it’s better to replace them.
