I have just rebuilt a 1985 50hp Force/US Marine outboard and when I go to turn key over it pops the circuit breaker box by the ignition coils. I can use a jumper and get starter to turn flywheel so I am kind of stumped. I changed the in-line fuse to no avail and that is where I am. I took pictures and have a manual so I am positive about wires being in right place and double checked my grounds. Any suggestions would help at this point. Thanks
