I'd start by cleaning and exercising both the AC select switch and the AM/VM switch. Many times it's just a dirty connection inside one of the switches. If that doesn't help we will have to dig deeper.

It really would be good if you could somehow swap the regulator somehow. I've seen a couple machines where the transistors on the regulator were the cause of both intermittent and constant high voltage. I just replaced all 3 transistors and it was good to go. Is there any way you could swap...

I believe you assumption about the clamps is correct. The rubber isolator on the clamp makes a brown stain on the white wires over time and the wires near the center of the bundle stay clean while the surrounding ones get brown marks on them. First time I saw it I thought the same thing, I...

FYI, if still in doubt, that wire needs to attach to the wire with the red shrink tube on it. One end of the capacitor also attaches to the red stripe wire and the one that you are questioning. So it needs to be in the 2nd position from the right in your picture. So what's the background here...

Everything the guys above have said is spot on. To add in my .02$ .... If you need to run the 2 water heaters, go with the 803. I normally don't suggest anyone with electric heat or hot water run an 802 simply because either of those 2 will consume most of your power. 802's provide plenty of...

Yes, thanks to both LITD and Guy, your kind words are definitely appreciated!

With just 590 hours I'm surprised your oil pressure is that low. Normally I would expect to see 28 psi or higher. Did you happen to verify pressure with a good mechanical gage? If you end up tearing the motor down to inspect it, take a look at the oil pressure relief valve. You may be loosing...

If interested I'm in RI ( North East ) and have 2 Mep-003A's done, fully serviced, tested and ready to go to work. One is a real nice 1992 Govt. refurbed unit ,done with 131 hours at the time, now with 429 hours and tri-color CARC paint. The other unit has about 1100 hours on it and has a few...

A bad CVT1 can also cause no power, however, I think the test you tried per Tripple Jim's suggestion also takes the CVT1 out of the equation. I still think you need to double check all your connectors. If nothing is found there, might need to start looking at the Gen head.

No, I don't believe that is true. I'm no electrical engineer, but I don't see why you would have a problem with your 120V loads? In a 208v 3 phase config. you still have 120V from each phase to neutral, but you will have 208v ( not 240v ) between any 2 phases because they are 120* apart instead...

On the older 003A's another thing that can cause random "no-power" is a poor connection at one of the bulkhead fittings on the back of the control cubicle or down on the AC reconnect box. Try removing and reinstalling all of the wire harness connectors. It sounds like it worked while you were...

If your floats test out ok and the problem persists there may be a problem with the float control module or the fault panel on the machine. Pull out the zig zag shaped dual float assembly as Guy suggested, and ohm out the lower float, make sure it's working correctly. Also note: the float...

Good one Guy! (y) ( hopefully your wife doesn't read these articles! )

I have a suspicion that your plunger guide has skipped 90* If you are able to get it to start again, let ir run a bit and see if it gets abnormally hot, especially in the valve cover area. If so, I bet the dogbone skipped but did not split open. I've seen this a couple times before. It usually...

I also have a used one I can part with, if you end up needing a switch.

The pumps are very simple to open up, clean and reassemble. All that's in there are 2 check balls, top and bottom and a magnetic plunger that vibrates back and forth to move the fuel. Most likely yours are just stuck from gum buildup. Take off the base with a 5/8" wrench, remove the strainer...

Chris, if you feel the injectors are not spraying fuel, I'm in RI and am set up to test, rebuild and set the pop pressure on these injectors. If you are getting no smoke then for one reason or another you aren't getting fuel into the cylinders. It seems very unlikely that both injectors would...

If I read correctly you are getting fuel to the injectors but no smoke at all? When you attempt to crank it have someone look at the fuel shut off solenoid. The solenoid should pull up and the throttle linkage should lift up to full open. For the return lines, yes you will have fuel coming from...

Welcome to the forum. ANYTHING can be repaired. The guys here should be able to walk you through it. The first thing I would do it exercise both the AM/VM and AC select switches ( with the machine off ) Cleaning the switches with contact cleaner as well would be recommended. Then retest. Also...

Don't worry about keeping it at 75% output. You don't need to be that high. You just don't want to go for long periods of time with very little load. Worst case if you run at little load ( under 25% ) for a full day or more just turn a few extra things on every couple days for 1/2 hour or more...
