Customer Question

I have an Onan 2800 Microlite that slows and quits when I put a load on it such as the A/C or even the microwave. I have cleaned the slip rings and am getting only 19 ohms of resistance. I can't find any specs to see if this is correct. I am also questioning the voltage regulator as a possible problem. What should the correct resistance reading on the slip rings be? What is a good test for the voltage regulator?

Hello!
My name is ***** ***** I am going to assist you with this.
The genset slowing down will not be caused by slip rings or voltage regulator. This is most likely a carburetor issue.
What is the model number of the genset?
How long has it been since it was run regularly?
How long has it been since the genset had a good tune up?
