2003 Johnson 115 electrical problem

Hello everybody, what could be causing the fuse on a 2 cycle 115 johnson to be blown? I narrowed the fault to the store wire (black with white stripe).Whenever I disconnected the wire everything is ok but as soon as I make contact the fuse blows.I have checked the wire in its entirety and nothing looks or feels usual, any suggestions? Thanks for any reply

 

What do you mean by "store" wire ?

 

Sorry, I meant stop wire

 

Your best plan would be to buy a good workshop manual that covers your engine. In there you will find wiring diagrams and diagnostic procedures. I vaguely remember having a problem with a Johnno that blew fuses, and the problem was in the control unit, but you should go one step at a time with the troubleshooting routine laid out in the manual.

 

I'm trying to source one but I'm not seeing any online

 

the problem is going to be in the control box harness... or the key switch... and the wire should be black with yellow stripe.... not white stripe... the black and yellow stripe is a direct ground to the engine .... a outboard uses a magneto key switch.... in this case ... the magneto wire is grounded to kill the ignition.... so you will have a pinched or bare red wire somewhere in the harness... and its grounding to the red hot wire.... power is never applied to black and yellow wire... .
red.... hot from battery side of solenoid to key switch
yellow and red.... crank
purple.... choke
grey ..... tach
yellow and black... kill
pretty simple... but you could have the wrong type key switch..... i would check that first....
