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. :)

Wow, air 92 degrees, dewpoint 66 here. I'd say it's unusual for MA to be hotter than NC.

The engine is air cooled, and designed to run around 1,800 RPM. Running it slower definitely risks overheating because of the slow turning fan. I'm not saying you'll definitely have a problem, because the cooling system has extra capacity in most conditions, but you should probably monitor the...

Cool about the woman. Language and dialects are fascinating. I've known a couple German born people here who sounded only slightly different from locals. Sometimes it gets so close that you can't be sure it it's because the person isn't a native, or just speaks a little differently. End of...

No problem at all, I just wondered which you were recommending. It must be very interesting to spend years in a country where you speak your native language so little. I'm used to talking to people in the US who moved here from non-English speaking countries, but not the other way around.
