I was plugged into shore power. Without cranking the engine for a couple of weeks, the chassis battery didn't have enough power to crank the engine. Gas was below 5 gallons, so the generator wouldn't start. With the radio fuse and radio memory fuses pulled, cranking the engine after a month of sitting idle was not an issue. One of the fuses was #25, but I can't remember the number of the memory fuse. These are two big scavengers of the chassis battery.
