That's strange. A 12V panel made for battery charging should put out 18-20 volts open circuit. I have a 20" square panel on the roof of my Dodge van, with a charge regulator between it and the battery, and it'll charge 3 amps in full sun.

I've been using Soneil chargers for 12, 24, and 48 volt applications for quite a few years now, and find them to be reliable and accurate as far as when to switch off the initial high-rate charge current and go to the steady maintenance voltage. They tend to be on the expensive side, but you...

I thought I was done, but the temperature compensation came out a bit differently from my 12V version, so I'm going to change a couple things. I hope to have it ready by the end of the week.

Yes, I do plan to do that. It should be only a few days.

Yes, I have one in my own 003A and a member here has a Beta unit in his 002A. We're getting quite a few hours on them between the two of us, running both with and without a battery connected, and they're working as planned. I have parts for two more, and will put them together shortly. Parts...

I had some gravel delivered a few years ago and talked to the driver. His Mack double axle (or was it a triple?) had been well over a million miles. I thought I was doing pretty well to get mid 300,000s on my '73 Dodge van, with one engine rebuild and a couple transmissions.

That's for sure, Jerry. 2,000 hours is about like a car going 100,000 miles, so that engine's 12,000 hours is like a car engine going 600,000 miles. Not being used to working around stationary equipment, I have to convert to car miles. ;)

Engine speed determines frequency. Maybe a loose connection could cause enough spikes to confuse a frequency meter. Edit: Victim of missing new page, so I missed smurph's post above. I still think it's worth checking for loose connections.

Interesting idea! Actually the one I use is my neighbor's. I help him keep his Ford NAA tractor running and he doesn't mind when I use his splitter. I wonder if he'd notice...

The pumps are positive displacement, so the pressure the pump can develop will not be reduced by running it at 1,800 RPM. The specs almost certainly say that 3,600 rpm is the maximum allowable pump speed, not a recommended speed, and the pump life will be longer when operated at 1,800 than its...

Is it possible your current 9 hp engine has a built-in gear reduction? Some splitters use them and some don't.

It should make a great splitter engine. The splitter I use has a Briggs and Stratton engine with a reduction gear to the output shaft. A direct drive at 1800 RPM might make a nice fast split cycle. It won't be light though. :-)

Sewerzuk pointed out that you can power a house or shop from two phases of 3ϕ power as long as you don't overload those two. You'll have 120V and 208V, and most 240V loads are OK with 208. Check out his videos about MEP-004As.

One wire of the capacitor is connected to the 24V supply and the other is connected to ground. Simply cutting either or both wires will take them out of the circuit. I was a big fan of leaving them in place for RF noise suppression since I'm also a ham, but since cuad4u posted evidence that...

I understand. It was near 70 here today, but it won't be tomorrow, and Thursday's high is going to be in the 20s. That's pretty cold for NC!

Sounds good. I have a couple prototype "24V" regulators getting some hours on them now, and will have the production version available in a couple weeks. Good work on making your own. Sorry for the hijack, still waiting to hear about Mastrman's meter, and whether the problem was a bad ground.

Is this the main control regulator for the exciter field, or a 24VDC one? The cost of materials isn't a lot for the DC regulator, but fabricating a housing, assembling a board, testing, and potting takes more time that one would guess it does!

It's nice to bump in to a fellow Ham. I've been one for something like 20 years. I need to go to a hamfest! I haven't been to one for a few years now.

OK I understand now. You need to use a volt meter or a multimeter configured for measuring volts to measure between the connector and ground, not an ammeter. The panel meter gets its power right after the "start relay", which closes when the oil pressure comes up. Does the engine start and...

I'm not sure what the "single socket" is you're referring to, but if you have an ammeter and put the red lead on something like a live 24V terminal and put the black lead on ground, you create a short circuit that will either blow a fuse somewhere or wreck your meter.
