Tom, sounds like you are actually ok on the AC side. 120V with the knob up 3/4 of the way is perfectly fine. I wouldn't even bother looking much further into it. Maybe just try the 240v setting and see if you have around 240V between L1 and L3 on the buzz bar using your multi meter. Also see...

Tom, once you verify the actual AC voltage you are getting, if it is low even with the adj. knob cranked all the way up, I think you can adjust it further using the variable resistor (R12 or R17 depending on which regulator you have) on the voltage regulator board. Try looking through the TM...

I'm sure many of you have read lots of threads about machines with the output voltage going high:deadhorse:, but this one might have a little different spin to it. When I first got this machine I noticed an intermittent high voltage problem. After inspecting the VR board visually I noticed that...

You could probably winch it up with a chain fall or come-a-long. Would be easiest if you could get some pipes or something under if for rollers. I've loaded and unloaded skid mounted MEP-004's from a deck-over trailer this way before. Wasn't too bad.

The motor itself will run just fine, the problem will be with the side load on the crank bearings. The bearings aren't really designed for much of a side load, so excessive pressure on the crank will probably lead to premature failure of the main bearings. You might be better off with a setup...

Ok, so here's the latest. I purchased a couple of the TI tachometer chips that PeterD suggested. I got one hooked up on a bench and got it to drive the HZ gage from an MEP-002A running in essence off utility power using an AC and a DC power adapter. Now the next step is to build a circuit to...

Latest update.... I'm abandoning the circuit I was playing with and have ordered a few of the LM2917 chips. The other circuit will drive the meter at 60Hz but is not giving me any movement on the needle as the frequency changes, no matter what I use for resistors and potentiometers. The only...

Peter, thank you for the info, I'll take a look those IC's today. Meanwhile, I tried the other circuit on the generator Friday night but found (as I suspected ) that a 4 Hz change at the generator only registered as about 1 Hz change on the meter (the circuit showed a 100uA meter instead of our...

So, the other day I hollowed out one of my dead transducer bodies ( found a bunch of stuff buried inside the potting material ) looks like it had not only a circuit board, but also a transformer or coil and a pair of caps about the diameter of a AA battery down the bottom. I made another board...

Do you already have the pump you plan to use or do you need to buy one still? If you still need to buy it, why not go with a lower RPM pump so you can make it a direct drive?

Sounds like an awesome idea. The 003 motor should be plenty of power for your project. Remember, HP ratings are not equivalent across the board for gas, diesel, electric and hydraulic motors. I don't think you need a jackshaft setup to get the speed up where you need it, just a pulley on the...

This morning I threw together a test board using the schematic I posted Friday and it worked... sort of.... The 5K potentiometer is way too big and sensitive. I ended up needing about 30 ohms at 60hz so I replaced it with a 200 ohm pot that I found and it works great so far, just sitting on a...

Looks very familiar.... I have the same gage on one of my units too. I had cut out an adapter plate and mounted it in place of the analog gage. I recently lost yet another transducer on my other machine and was interested in a way to drive the original gage,( just for authenticity) and have a...

A quick Google search turned up this circuit design for a frequency meter. Being that the MEP's use 200uA gauges, could this circuit be modified ( possibly by changing the resistor value ) to work correctly with the OEM gauge?

The basic trailer looks similar to the smaller 3,5 and 10K generator trailers, but not quite. I've never seen one with that boxed in area behind the wheel wells where the brake lights are mounted. The generator trailers I've seen are flat, even with the deck in that area and the lights are...

If all the obvious stuff checks out, use the schematic and start checking things in the starter circuit like the relay, switch, lockouts etc. Sounds like you have battery power at the starter but no signal to the solenoid (you might want to confirm this by checking for voltage on the small wire(...

Here is a similar thread from a couple weeks ago talking about the transducers and meters. I know next to nothing about electronics, but, just like it was mentioned in this other thread, it would be fantastic if one of the electronics guru's on this site could come up with a simple, innexpensive...

Guess in some respects I'm lucky. I live near the town transfer station and we are allowed to bring all our motor oil there for free recycling. I bring 5 gl at a time with no questions asked. Other towns in RI only allow 5Gl per year and they take down your address and keep track. Problem I see...

I think you just answered your own question on the motor oil... since you use mostly synthetic and don't have much used oil anyway, why take a chance with it?? What will you save in fuel cost each year, <$20 a year? Why chance causing hundreds of $$ in damage to your genny for the sake of a...

AWESOME! New batteries and you're good to go [thumbzup] If you don't mink me asking, which batteries did you go with? All 3 of my generators need new batteries but I don't want to throw down $600+ at the moment, but I really need at least 1 set. I'd be interested to hear which brand has given...
