Onan Generator Troubleshooting

Troubleshooting an Onan Generator can be done in several steps to prevent the need for repair and to slow the wear and tear process down. In essence, troubleshooting leads to a longer life for your Onan Generator and improves the quality of your investment in the product. There are three things you yourself can do in the comfort of your own garage or basement. These include checking the engine, checking for oxidization, and faulty displays. Follow these troubleshooting tips to extend the life of your Onan Generator.

Checking the Engine
Let's begin with the engine of your generator. Not only can repairs to the engine be time-consuming, they can be costly as well. Most of us have been there before when we go to start our generators and nothing happens. You push the start button only to release it a moment later and the engine shuts off. This usually means that the voltage regulator is not receiving enough voltage from the control board. What could be the problem? Grab a voltage meter and plug it into the voltage regulator in the generator. The voltage regulator should be reading equal power to what the gauge on the generator reads. If not, it is time to call your trusted and certified mechanic to discuss repair options.

Checking for Oxidization
Another cause of your problem may be due to oxidization. Sometimes generators do not supply enough power in general. To ensure this is the cause of your problem, check the output gauge. If the gauge reads a zero, this is problematic. Zero readings are typically the result of oxidization of the slip rings on your voltage regulator. An easy fix to this problem is buying some new slip rings and replacing the old ones. Your best bet is to buy them from your Onan dealer and bring in the old ones if necessary to ensure you are buying the proper part. An easy way to prevent oxidization is to keep your generator out of any water.

Faulty Displays
Another common headache for Onan Generator owners is when display lights and display indicators do not turn on. Before you stress out, check the circuit breaker and make sure it is switched to the "on" position. The circuit breaker is located in the back of the Onan Generator. If the switch is in the "on" position, you'll have to do a little more work to find out what the problem is. Usually, this means your generator is suffering from an electrical problem. This also means your generator is damaged and no longer has the ability to maintain power. Most likely you will only be able to keep your generator up and running for short bursts of time. In this case, contact the Onan Generator dealer and discuss whether or not it is more feasible to have the generator repaired or if you are better off buying a new one.

For the best advice it is best to contact a certified distributor or dealer in your area. For repairs, always contact a certified Onan technician or a trusted mechanic. This can save you both time and money.
