I have a 1981 overniter with an outboard. All original and meticulously maintained and cared for. Before i start the motor my fuel gauge wiper and running lights work fine. The fuel gauge springs up and lights and wiper works. When i start the outboard, the fuel gauge barely moves off the empty line and the lights and wipers no longer work. When i leave the boat overnite, the fuel gauge works as do the running lights and wiper until i start up the outboard. I checked the 6 dashboard fuses and all seem to be fine. Is there another fuse block in the boat I should be checking or go in a different direction. Any help would be greatly appreciated.
Thanx
