You're right, I was the one thinking backwards. :)

No, a MEP-003A is a 10 kW four cylinder diesel unit. Maybe a MEP-831A.

True enough. For those of us who occasionally run tests with resistive load banks of some sort, those will have a power factor of 1, so as you said, the meter will read 20% low. This is likely why a lot of reports of load tests come back with "it easily ran at 125% for an hour." It was really...

By the way Dougski, I thought I recognized your avatar photo. Never say die. :)

I'm glad you found the answer. I've never had mine apart to see how they're arranged.

Guy is not arrogant. He spends a huge amount of time here purely to use his experience to help others.

One thing that could help a lot is a good solar charger of the type that has a real charge controller.

I don't think so. He bought a regulator from me a year or more ago, and I got the impression he was selling off his last one(s) at the time.

Amazing. I guess if you can't break it free, you could get another similar pot and install it in the board.

There's also a sensitivity adjustment pot inside the unit. I adjusted mine a little to get it to be reliable. It's been a couple years, but as I remember, with the power on, I turned it until it just screeched, and then a little farther. Hearing protection required!

If you want to use a penny, it'll have to be an old one, since they've been copper plated zinc since 1982. Even then it won't be pure copper than can be annealed to a full soft state the way gaskets need to be.

My 003A starts the industrial 5hp 1750 RPM motor on my air compressor, but you can tell it's working at it. I'd expect the 004A to be able to start half again more, at least. Consider getting variable frequency drives (VFDs) for your 3-phase equipment. I got one for my milling machine years...

Thank you Tracy, I'm glad you got things up and running. And you're right, it's fun when you can run big loads like an air conditioning system with one of these.

You mentioned cold weather, but you're in Tennessee. Are you referring to Tennessee winters? I'm in northern NC, and have had no problems with 15-40 on a cold morning, which rarely gets lower than about 15F here. You may know already, but I believe Rotella's synthetic oil is actually not...

After doing a little research for David, I found that while the 1N1204A and 1N1204RA are in short supply, their 600v counterparts are not. The 1N1206A and 1N1206RA are in stock at several suppliers, Mouser being one, for about $6 each. These days it's not surprising that they quit selling the...

Yes, but all diodes have positive anodes and negative cathodes by definition. The thing you want to be sure of is which three have the stud as the cathode and which have the stud as the anode, since there are three of each in the assembly.

Not bad thanks David. Busy keeping up with work and trying to empty a house I sold (not where I live now). I trust things are OK at your end.

Plugging the part numbers into octopart.com shows several suppliers of small quantities. You may not be able to get both from the same supplier at the moment, I didn't check that thoroughly. Alternatively, you can probably find diodes with similar or higher ratings with the same packages...

You can periodically highlight the test of your reply, right click, and hit "copy". Then it's in your clipboard, and if the board logs you off, you can still start over and hit "paste".

Group 51 batteries are currently $85 each at Tractor Supply. Let's hope he's in a warm part of Michigan. :)
