Onan 4000 generator troubleshooting
I have a 2018 Chateau 31E, and my Onan 4000 generator will not start. It cranks but will not start.
Fuel tank is full, batteries are charged, I tried starting with the RV engine running, and connected to shore power. Generator oil level is full, and I tried replacing the spark plug. I cleaned and re-connected the ground connections, and I even tried connecting a ground wire from the generator engine to the RV chassis. When I prime the generator I hear the fuel pump running, and I smell gas, so it seems to be getting fuel.
An RV dealer did some troubleshooting and said it wasn't getting spark, but they were unable to fix it.
I measure good voltage at the input of the coil, and the output of the coil has voltage when cranking. This output is the wire to the spark plug, so it makes no sense to me that there isn't spark.
Any suggestions on what troubleshooting steps to do next?
