My onan hdkak 8000 will start but not stay running, flashes

Customer Question

My onan hdkak 8000 will start but not stay running, flashes 3 times and gives a service fault of 15 even when breaker is disconneted. Any ideas, inverter? Stater maybe.

Code 15 on this unit is Inverter Under Frequency. It is bad news.
The only check you can do is to shut off the breakers at the genset, so no outside loads can interfere.
Start the unit.
If it continues to run now, you have a problem in your coach.
If it still shuts off, your inverter is bad, and will need to be replaced. This inverter is about $2000.
