    Great site been reading many post under the Onan Generator. I live in an area that floods often and the electricity gets shut off so I need backup power. First generator was an old Wisconsin two cylinder gas powered genset. Worked good but was 110v only. The other issue was it was gas. I had to have enough gas on hand to run the generator since if i left to get gas they would not let me back. So what fuel do I have on hand? Home heating oil (off road diesel) Bought a Chinese one cylinder 6K diesel genset. Work well until I overloaded it and popped the AVR. Replaced it until the next time I overloaded years later due to an air compressor I forgot to turn off. Replaced the AVR still no electricity. Did some test and the rotor was bad. Replaced the whole alternator assembly. Still no electricity. Screw this I am going to put in a whole house generator and do it right! Auto transfer switch under ground wiring and a relay to shut the air compressor off. So I bought a recondition Onan 20K DGAB 1993 K930525648 Spec 50794F 4 cyl water cooled genset with a little over 1000 hours on it with a sixty gallon fuel tank. I don't need the fuel tank. So I removed it and still have it. It has a two wire remote start that did not work due to a blown fuse on the engine control board. Replaced the fuse and now I have crank and start only on a warm engine due to no glow plug activation. So back to the manual. It does have a board with a relay on it that controls pre heat ,delay start and delay off. But after taking the board out and taking a close look the relay does nothing not connect to anything. That's weird? So back to the manual and what I need is a 300-2898 board that has all the options on it including preheat. Found some on the internet but everyone was out of stock. So I made one out of a Hella SPDT delay relay. I set how long of a delay before start and turn the glow plugs on first for 10 seconds. I have bench tested it but have not installed it yet. So far I have the pad poured and all the conduit ran underground from the pad to the house. Bought an auto transfer Onan 200 amp switch. I have an electrician who did genset installs helping me. I hope this genset was a good choice and I have it up and running before the cold weather sets on. Like I stated before great site and I have learned something already by reading old posts Thanks Oana Gen ID Tag.jpg Onan Gen.jpg s-l1600.jpg
