wildebill308 Report post Posted October 31, 2022 Well glad you are doing better. Are you pushing the button to prime the fuel to the generator before you are trying to start it? Don't crank for more than 30 sec. If it doesn't start re prime and try again. As it hasn't been started in a while this may take several tries. Let us know.

Went inside coach and tried to start just for grins. It started and i ran it for about thirty minutes. I have no idea what changed. I must be living right, Again, thanks for the help. dee Share this post Link to post Share on other sites
elkhartjim Report post Posted October 31, 2022 I would let it run for an hours with 50% load. Run the air conditioners to get the load. Share this post Link to post Share on other sites
rayin Report post Posted November 2, 2022 To me, that sounds like a corroded battery cable connection, either on the battery or genset end of the connections. Remove, clean, re-install all wiring connections, especially the ground side of the circuit. Share this post Link to post Share on other sites
