I tried starting my 6g after about a week of not riding her (cheating on her with cbr1k) & she wouldn't fire, ...
no fuel pump sound.
I checked the A Main fuse first (A&B fuse ok) which seemed a bit tuff to extract. Once out it was obvious why, the connecting wires in particular the red wire had burnt a hole thru the plastic. (Picture below )
So my question is what is the cause of this? Other problems?
When connectors get a little corrosion in them, the resistance jumps. More resistance for a given current produces more heat, leading to a melted connector body. So your root cause is most likely corrosion. A good clean and addition of dielectric grease for prevention would be in order.
This is what happens when you play with fire (CBR1K)--you get burned! Stick with your steady GF--she may not be quite as fast, but she knows how to treat you right... ;)
