Just walked out to my motorhome and heard the fuel pump running on my generator, tried to shut down the fuel pump with switch located on the dash and the main switch on the generator no luck. I had to pull the fuse located next to the main start switch to stop. I have the 8000 8DHKAK diesel generator, does anyone have any idea what the problem is? Very strange since noone was trying to start the generator, fuel pump started on its own. Halloween was yesterday (strange)
