#1 question how much gas is in the RV tank
won't run if tank is below 1/4
#2 question status of your 'house' batteries
IF discharged, genset might not stay running
is battery disconnect on or off, your converter suplies the power for the batteries and the genset ignition
most Onan's no longer have their own 12v power circuit
#3 LOW oil in genset will cause this
these conditions don't care what model# the genset is
except that old 70's models have their own 12v power
I can explain it to you.
But I Can Not understand it for you !
