The maximum current in three phase should be 17.3 amperes. Running 3 circuits to L0 for 120 volts results in 2076 watts per leg for a total of 6228 watts. At PF of 0.8, that is 5 kw. Running 3-phase, that would be 3 legs of 208 volts at 17.3 amps gives 3598 watts, the factor of the square...

And quite a few more than labeled. They can run all day at their rated output, no big box store generator can do that. You can safely turn 15 kW loads for a bit. If temperatures are mild, even longer. One horsepower is about 748 Watts. So a 10k generator is producing about 13.4 horsepower...

Also the governor solenoid, fuel pumps, remote fuel solenoid, three relays(start, safety bypass, preheat), glow plugs, intake heater rewire (series to parallel) and the panel lights. The run time meter should work on 12 volts. Price all the above and you are looking at over $1000. To save $80...

Use the 3/8" NPT boss on the top of the tank for a desiccant breather. Cap off the remote fuel line to keep it clean. You could install a tee on this port so you could have the breather and remote fill but that would be more prone to damage. Always store the generator with a full tank and...

The $30 Harbor Freight Tools diesel compression test set should have the adapter for testing through the glow plug port. Back when the TM was written, there were very few diesel tooling manufacturers and most compression gauge test sets were for large engines without glow plugs. Hence the use...

Glow plugs are not needed if it is above 50 F. Have you tested compression? Since you have had the cylinder head off, what did the bores look like? I have noticed a good number of 002A/003As have new engines. These have Onan data plates on them with 1990s contract dates. Just thinking Onan...

The reason the T-diodes are so expensive is that they are toughened against radiation. That is a silicon 3 ampere power diode with 400 volt rating. Use a regular 1N5404 with absolute certainty. The reconnection switch (120/208 3 phase, 120/240 single phase and 120 volt single phase) is an...

Further measurement tonight on the transducer in my 002A showed 55 Hz at near 0 micro amperes, 60 Hz is 90 micro amperes and 65 Hz is 180 micro amperes. Far more sensitive than my digital frequency meter at 18 micro amperes per Hz. The transducer is a bit slow. There is no way to retrofit to...

Have you checked to see if the injector pump is delivering fuel to the injectors? A sluggish IP will make purging the lines very slow. And if you didn't purge the lines by keeping the fuel line nut at the injector loose while cranking until you see fuel drip, it will take forever to purge the...

Partial testing of the frequency transducer showed 80 microamperes at 50 millivolts when running at 60.5 Hz. Just removing the load of 1250 watts (space heater) had the current jump to 110 microamperes for a frequency jump to 61.5 Hz. I had another issue consuming my time so this is the limit...

What is the resistance of the frequency meter? You could have a customer for that part alone.

Yes, the K1 relay is on the A1 terminal block which also has the diode mounted behind it. K1 is labeled as a start relay but in reality, it is the oil pressure/over-temperature relay. It is bypassed by terminal 28 during the start switch operation. Once the low oil pressure switch makes...

Bringing new life to this thread...the capacitors on the fuel pumps are critical because the fuel pumps are solenoid actuation and every time they click off, a reverse pulse of electricity flows. Reverse current is hard on the internal switching and can damage the voltage regulator on the...

Not as much as it to prevent water intrusion. From the looks of your unit, it has never gone swimming. If you keep it out of the weather, you should be fine. There isn't any real heat generated in the transducers. Only a few microamperes. I measured between 20 and 554 microamperes for an...

My frequency meter is corroded to death. I just bought a digital multimeter with frequency measurement capacity and use that. As a bonus, it is true RMS, meaning proper measurement of alternating current. If your transducer is working, it would be best to keep it. Have you tried to plug the...

Knocking means timing or delivery quantity is out of specification. It would help to compare the fuel control lever position at governed speed, this is a delicate measurement but you have a good comparison. It could also be a leaking delivery valve, making injection pressure too low which...

The 002A and 003As were designed in 1977 and were replacing 5 and 10 kW gasoline sets as those were retired. New ones were being built until the 1990s. Onan sold a good number of replacement engines, noted by an Onan tag on the blower shroud. Much has been said about the durability of these...

Partial load test today, two 1250 W space heaters. Frequency with just one is rock stable at 60.5 Hz as adjusted. Put the other one on and still, 60.5 Hz. Voltage is rock stable regardless of load, indicating the regulator is perfect. When disonnecting the load, frequency jumps to 62.2...

Well, they now know the price is somewhere between $24 and $274. They won't sell many at that new price.

Latest repair/refurbishment has been on the wiring. The white wires are coated on the outside with Nylon which has weathered, cracked and flaked off in many areas, mostly the starter/high temperature cut-off and tank switch. Plus the #2 wires to the starter are not coated and the fiberglass...
