first time .... run the unit every month or so on different projects. so. ive been running the unit all week (its duel fuel been running it on gasoline and on propane all week) works great. at the end of the day, unit was shut down for a few hours while i doing something, went ahead to attempt to start it but totally dead. the hour meter wasn't even clicking away. normally if i'm up in the air i can engage the up/down valve by turning on kill switch and letting gravity pull me down with out starting. but it seems like its not getting any power to anything. Any thoughts anyone?
