Motorcycle Repair: 1984 cb650sc has NO power?, wiring loom, jc whitney

Question
QUESTION: Bike was in perfect running condition and while riding one day it just shut off. Now turn the key and nothing. Battery is bad new. I replaced main fuse also, but aftermarket was a different type instead of metal bar it has a plug in fuse on top?

ANSWER: Hard to diagnose this but it could a problem in the ignition button or even the key. Do  the lights come on at all or are all electricals dead?

QUESTION: no power what so ever. Thought it was main fuse so I replaced it with aftermarket one described. I also bought an aftermarket ignition from JC Whitney. Still nothing different. However, when replacing it found the plug on ignition was melted pretty bad. Any help would be great. A Nighthawk that gets 49mpg is better then a 425hp mustang that gets 15 mpg.

Answer
If the battery is good and you checked the fuses then you probably have a bad connector or short somewhere. The only real way to track this down is to get a multimeter and test the wiring loom at various points. You'll probably need a wiring diagram to do this.
