Onan Generator Troubleshooting and Repair

The RV is still in the shop (long story) and the trailer is still being built, so I’m sort of in between projects. I worked on this Onan Marquis 7000 generator for a little extra money and thought it might be interesting to some of you.

Note: This is NOT the generator from our RV. This is from a stage trailer that my church bought.

When I got the generator it wasn’t running. Once I got it running it wouldn’t produce any power. It turned out the carbs were all gunked up, the voltage regulator was bad, and the brushes needed cleaning.
