Since you must disassemble the unit to reach the components, prepare some wrenches and screwdrivers. Overall, you are going to need a functional multimeter around to exam and inspect essential readings of the generator components. As a result, you have to make sure that you got proper tools and hears before assessing the Onan machine. Without the right tool, it’s highly likely that the troubleshooting process would not provide you with a definite result. All things considered, the performance of Onan power generator relies a lot on the smooth cooperation between its various components. If everything goes smoothly, the rotor of the machine would start receiving DC voltages soon after the rectifier turns on. A set of relays in the board open and close as the oil pressure change which determines the rectifier status. Upon starting, the generator control board would deliver currents through the + terminal of the rectifier. In the case the Onan generator you are using happen to lack a regulator (notably NHE and BGE models), it would have a bridge rectifier. Technically, the regulator works as a built-in protection against potential overloads of the machine. Depending on the current situation, the regulator increases and decreases the loads before transmitting them through the unit field circuits. If nothing goes wrong with the board, the regulator should receive field flash voltage and then preserve stable applications of varying loads on the stator. That means the board would promptly stop Onan generator from working once it detects shortages of fuel and fuel pressure. Generally speaking, the control board regulates primary functions and the most important one is to keep the unit supplied with enough diesel (or LP gas). As with other devices, call a certified electrician to fix the unit in case you don’t really have much confidence in your electronic skill. Take a look at the information below and you could take care of the issue of “ Onan generator starts then shuts down ” in no time. Onan Power Generator: What You Need To Keep In Mindįortunately, troubleshooting Onan generator is not a difficult task so as long as you could grasp the fundamentals, everything would turn out to be fine.
