Since the 28 volt system is an add-on, it isn't properly engineered. Excess voltage+current is dissipated as heat which fries the regulator. The easiest method? Skip the wonky float switch and plumb in an overflow line back to the belly tank. Install an adjustable needle valve in the pump...

Voltages from the engine-mounted alternator is far from stable, most hand-held voltmeters will sample the highest peaks which is why they read high. This also plays havoc with the float switch, the 002/003 series use the same fuel pump and have a magnetic float switch for the same purpose, only...

10 Hp out of 42 cubic inches? Yes, that is quite conservative. You should see at least 15 Hp at 3600 RPM in stock condition. Advance timing 3-5 degrees and run premium gasoline? 20+. Just don't think you can go much faster than 3600 RPM.

The Yanmar diesel should be fine with gravity-fed fuel as there is no return lines. Return fuel is used to cool injection pumps as well as provide displacement for the injector's needle (sometimes called a pintle). For a running time meter, find a circuit with 12 volts on it when the engine is...

As long as the fuel tank is clean, a pair of Wix cartridge filters with drains is plenty. Clean the strainers on each fuel pump, they are probably nasty. You will probably need new gaskets for each. Facet-Puralator 42370,

It is an old-fashioned layered metal strainer, held in place via a nut on the threaded central bolt. Only expensive because very few were ever dirty to the point of needing replacement. Fuel had already been strained by at least two electric fuel pump strainers. It is just a top and bottom...

Awe, shucks! If you have small fingers, you can pull the control lever assembly out without pulling the pump. You need a dental mirror to get it back together. Had the same problem with my 002A. The fuel was like wood stain. I used Pro Shot Copper Solvent IV on that part as it is more...

On 240 volt 3-wire? Yeah, that is a good load. 3-phase 4-wire? Serious over-load. 120 volt 2-wire? Getting good. What kind of load, power factor wise? This would be on the data plate of the motors. If just lights or heat, PF would be 1. Not going to explain power factor here...just tell...

These are magnetic breakers, driven off L1 (linear reactor) and trip point varies depending on connection. The trip current is adjustable by R3 variable resistor which is in the output box under the load terminals. This linear reactor also supplies the bulk of the field current through the...

Squirt some Berryman B12 Chemtool in the plunger area. Let it sit for a few minutes and try to work it. Don't soak more than 30 minutes as it swells o-rings. Since you have pulled the pump, Ambac has the manuals online. http://www.ambac.net/E64A353CC6034BE685460A71FD30F2F6.asp Should be a...

No need for flashing the field, this is done by the starter switch. On the frequency meter, these can be pricey. Before buying a replacement, check the transducer first by pulling it (4 screw terminals, tag before disconnecting and 4-#6 machine screws+nuts) and using utility power on the...

More like 0.51 gallons per hour. Impressive if actually generating 5 kW.

That is member sewerzuk. He does some awesome stuff, especially with generators.

Odd. Pressure usually isn't the problem if you have volume.

Sounds like there is some serious dirt in the injectors. When the injector "fires", the needle lifts, allowing flow. This means there has to be room for the needle to move back. This along with normal internal leak down is why the injectors have return lines for fuel.

Even at max fuel, each stroke of the injection pump is a bit over a thousandth of a cubic inch. About a half drop. Take the injectors out and soak in Berryman B12 carb cleaner.

Sounds like the needles are stuck in the injectors. If soaking in solvent doesn't work, reassembling without the needle springs and then using the injection pump's pressure may free the needles. If not, any diesel injection service shop that works on Bosch products should be able to help.

Very easy to pull the delivery valve, just remove the big cap nut on the center of the IP, then remove the 12 point nut under that cap. Clean it out and reinstall. No need to pull the pump.

The frequency meter transducer has aging capacitors. Probably not repairable as most are solid potted. Either get a replacement or retrofit a digital. The meters must be made of gold as OES wants $109 for them. The transducer can be removed and tested on house current, should output 100...
