This is most often caused when the genset is no longer producing any electricity.

Wow thanks that's like someone telling you that they have a flat tire and your answer is that there's a hole in it. This was a huge waste of money

You asked if I had any ideas what causes your issue, but provided absolutely no details - like a model number. Onan has made thousands of different models over the years. We can't just magically know which model you have.

But on all Onan models, that is the most common cause.
