I have a 40 hp mercury on an 18 ft. bass buggy pontoon. I bought it after been sitting up for several years. I got the motor up and running but evertime I push the ignition switch in to choke it blows the 20 amp fuse on the motor. I have a wiring diagram for the motor but not for the boat under the steering console, and ignition switch. I have disconnected the primer solenoid at the motor and it still blows the fuse. My guess would be a short in the primer control wire from the motor to the ignition switch. Any thoughts or ideas for this problem? Also the wiring under the console had some melted wires that I have replaced.
Thanks
