The fans on the 701A are 120 VAC and run off of the 120 voltage sensing wires that are at the main voltage regulator. If you are making 120vac at the T1-T2 coil and convenience outlet is hot then the fans should run regardless of the 24vdc system. There are some small 3amp fuses in separate...

The auto parts store battery tray solution only works on the 016E with the Yanmar. The smaller Yanmar leaves a lot of space. The latest 701A / 016B /016E conversion I have only requires removal of the screen and insulation in the end panel. To do that the rivets are drilled out. It can all go...

YES agreed. I misread followup post. I believe all the diodes on that board are to block misapplication of reverse current.

Hi, I'm Looking into possibility of the re-configure of the 400Hz units to either 60Hz 3 phase military or swap the gen end for a late model domestic type 4 wire end. I don't care about the few controls those are easy to refit. I assume the 400Hz is 2000 rpm and the existing governor can be...

The relays can be flipped. These are $150.00 list, silver soldered, hemetically sealed relays so their external appearance does not mean they are bad inside. I just finished selling a bunch of them from NOS boards used on other units that I bought. The big autcion site might still have a relay...

I never noticed rattle from the slide stops. I have bent the latching tangs to eliminate slop in the latch when closed. Makes it quieter and nice flush closure on the doors.

Those fuel hoses can be a PITA to replace. Chudov's site "Liberated Manuals" has the manual download for free. I also found complete Lister Petter OPW2 manuals on line so you can get the corresponding Lister part Numbers. The big control relays are behind the "wall" in the back of the control...

Good point on flakey ground. I have had that issue too from time to time. I suggest unplugging the solenoid and jumping it to the battery to prove it works then go backwards in the wiring from there. The wiring diagram in the lid on the box is the only one I have seen that includes the engine...

Very nice work. Thanks for sharing. The glossy paint makes it look real nice when it is applied on the smooth surfaces. It's a nice change from the ultra flat mil paint.

Jump that solenoid with a hot wire directly from the battery. I bet it works fine. I think you have a bad float switch or relay or connection somewhere. The low fuel float switch can be bypassed with a jumper inside the control box. I would have to figure it out. I did it once but did not...

looking good. Keep it going. I saw new control panel faces for $50 on the big online auction site. You will need one!

Were you able to check the compression? How long did it sit and how much did you run it when it last ran? If it is getting fuel and white smoking then either a bad injector or loss of compression is possible. Air in the fuel or bad delivery valve on the injection pump is possible too. I'm...

Okay, the white smoke means that it is getting fuel and that is a good thing. Did you confirm that it is turning over in the proper direction after the starter rewind? Is it turning over as fast as it did before all the work and new starter?

The throttle cable is a known weakness. It may do what yours is doing or it may slip a notch at a time. The only real fix is to replace it. I have adapted PTO cables to work as they are similar. I think the surplus places do have the OEM cables. You may try some way of making a clamp to...

The quick fix is to turn the maximum fuel screw in a turn or two until the speed picks up and holds. This is screw #2, fig 7.3, page 7-7 of the 202 page manual (not the 288 page manual). Turn it clockwise to make it pick up and hold. However, most likely it needs a full adjustment. Start at...

In order to have even firing order which is needed on a generator for smooth speed, a two cylinder engine must have both pistons running up and down together, firing alternately. This is essentially a large single cylinder engine as far a balance is concerned. If you are running on concrete...

Excellent work. Completely believable results. The frequency drop at full load retarded is strong indication that a lot more fuel is needed to maintain the set point. I don't know much about the 002 and 003, and every design is different to a degree, but if they have aluminum pistons too much...

Anyone have a spare electric cooling fan for the MEP-701A? The top one on my unit does not work. I switched positions with the side fan and the side fan works fine in either position. I tore down the bad fan and see nothing wrong with it, no burned wires, etc. It spins free just no response to...

The standard cable has a stiff rubber bushing on the end of it. That accounts for the gap. I say any fix that results in good cable action without binding or wearing on the side of the cable is good enough. If anyone ever has to run without the cable: The adjustment screw below the lever can...

Bleed the fuel system in this exact order. -Smell the oil dipstick to make sure there is no fuel in the crankase oil as would happen if the priming pump diaphram was cracked, leaking, or blown. -Bump the engine over in very tiny steps until the hand priming lever has the most stroke and the...
