Fuel pump fuse blows when you shut down. Replace fuse it runs. Turn off. Blown fuse. This is with a new battery and starter. It's a recently purchased piece and was told it had an illusive "short" somewhere. We have isolated most of the "custom" lighting etc. Ran for a month before this. Battery was cooked, starter brushes were worn past the clips. Help !

Disconnect the fuel pump and repeat it. Does the fuse still blow.

Disconnected fuel pump at inline connector near tank. Cranked it over. NO BLOWN FUSE.

Is it the fuel pump? And or the guage sending unit?

Going to try to fish harness out of frame cavity to search for chaffing first before dropping tank.
