No..... Not the ignition box, the external harness ground to battery wire melted insulator. Can't afford the nearly $300 aftermarket replacement. Any suggestions on re building/wiring the harness?
Is the plug still ok, and how long before the plug is the harness ok?
Post a pic if you can, that would be good. You can always rebuild a harness, its just a question of cost, and time.
Making your own harness is not that difficult. Question is can you salvage the plug that connects into the motor. If so, strip back the outer jacket to expose the individual wires. Cut off the damaged wire(s) back to good material. Buy quality waterproof crimp-on butt-splice connectors and using the same gauge wire replace any damaged wires. Make sure you don't cross connect any of the wires. There are several different materials you can use to jacket the new harness. Make sure all the connection points are waterproof.
Which ever way you decide to go, be sure you find out what caused the problem in the first place. Most likely it was a bad connection either in the motor connector, or at the battery or where the gnd connects to the motor.
