Very nice wiring job. I've had to do a little of that myself, and it takes some skill to make it look that good.

Still, 17 is good. About 5 hours more than the stock tank.

Another good looking generator. Is that a stainless fuel tank? How many gallons?

Nice work!

It's my understanding that we're not supposed to sell things in the forums, so I'll be posting the the classifieds when I get a few more done. I am trying to keep the price down to where it will be affordable. PM me if you like, and I'll try to be more specific.

Ha Jim, I wondered if someone would ask that. I work with a circuit board prototyper who takes the Gerber files and makes boards at a reasonable price. The default board is double sided, and can be silkscreened on both sides for the basic price. So I figured I'd draw a silkscreen layer that...

Thanks, I did order parts for a few more. I was planning to post in the classifieds when I get them together.

I bought an MEP-003A last summer, and thought it would be a good idea to have a spare regulator. When I saw the going prices for them, and since I have experience in this area, I decided to build one. I based it on the original 72-5020 board and its nearly identical brother, the 72-5338 board...

I had a chance to run my 003A yesterday. I varied the engine speed from lowest to highest, both with and without a 6 kW 240V load. The regulator current didn't vary a lot, but tended to increase with load and with increased engine speed. It was highest with the 6 kW load at maximum engine...

I have the meter wired to read regulator current, which on an 002A or 003A is not the same as the exciter field current. The exciter field current is supplied by CVT1 and the rectifier bridge A4. CVT1 has three sections, so it senses all three phases. It also has a control winding in each...

I'm not sure this makes my 003A more civilized, but it will let me understand when the regulator is working hard and when it's not. I found a small 0-2 milliamp meter in my spare meters box and made a shunt for it so it reads 0-2 amps. The wire that normally goes to terminal 17 on the...

Gotcha, makes sense now. It's on my list to put a strain relief on the side of my distribution box to get rid of the usual four wires dangling out the door.

Looks good so far. I'm sure you have a good reason, but why are you bringing the wires in the top instead of keeping everything going in and out of the bottom so it's hidden?

Thanks Jerry. Jim, the printer is really neat. There are different types. This is an $800 MakerGear Prusa Mendel kit. It extrudes plastic from a nozzle and the X,Y, and Z motors drive it around to build up the part. The laser imaging type that harden liquid resin do much higher resolution...

My MEP-003A's hour meter quit. Rather than buy a replacement 2-7/8" round type, I got a more commonly available and cheaper rectangular one from eBay for $14.95 delivered. Then I drew an adapter and my son used his new 3-D printer to make it for me.

Yes, it's inside my house at the box. Installing the meters at the generator has its advantages too, especially if the unit will be mobile. I look forward to photos of your setup. Isn't it great when good stuff goes to the dumpster?

The item title was/is "Rectangle Analog AMP Meter AC 50A + Current Transformer". The seller has a huge eBay store called "Asia Engineer". If you search within that store for something like "ac meter" it'll help. There are 20A, 50A, and 100A versions, digital versions, etc.. Since there is no...

I see right around 11 PSI at the gauge when running or priming. I suspected that the 10-year old fuel I'm trying to use up would make it slowly drop, but it's holding steady so far. A different length and/or angle of the fitting for the gauge might let you install it without having to make the...

I picked up a couple Chinese 0-50A Ammeters with current transformers from eBay. They come as a set, one meter and one transformer. They're set up so you run the wire you want to measure current in though the hole in the current transformer, and connect two leads from there to a meter. Now I...

I'm sure I'm not the first to make these mods to an MEP-003A, but here are three. Actually the first was already done when I got the unit. It's a simple battery disconnect that you can get cheaply: I added a fuel pressure gauge to the bleed port on the final fuel filter by welding a 1/16"...
