No darrsi, i've never jet washed it, don't know about previous owners though.
But not quite sure why you are replacing the ignition, fuel tank and seat locks, if it was just water getting into the box (plus I would guess a loose connection on the joint) causing it to ark and spark, just make a repair to that section of wiring useing a largish chocolate block connector or maybe two if you are going to replace a short length of the burnt part of cable, keeping the chocolate block connectors within the confines of the black box, give the whole of the inside of the box a goood blast of WD 40 and you should be good. Replacing all those switches will be very expensive and time consuming.
I thought about changing the ignition just in case I didn't manage to fix the wires, it's more of a backup plan. And if i change the ignition, i would have to change the fuel tank lock and the seat lock too, too keep using just one key. (i found the 3 of them for about 50€ on ebay). But yeah, that's just a backup plan if all else fails.
I'd like to literally replace that wire with another instead of fixing just the tip of it. That's because I can't be sure the rest of the wire isn't as bad as the tip of it, all i know is that it's stiff, and i guess it shouldn't be.
And thank you, it's the 2nd Fazer i have
It's such a versatile bike
Doesn't look like water damage to me either. Looks more like a short circuit or high current load causing the connector to overheat.
I guess if the connector spades are badly corroded it could cause a high resistance and result in what you see.
It's possible that the previous owner had fuses blowing because of this so just chucked in a big fuse to get around it.
After repairing this problem I would suggest checking all the other connectors and cleaning with Duck oil (not wd40) or acf 50 to prevent any future problems.
But since the wire is stripped at the tip, if water got there, wouldn't it short-circuit?
So, by cleaning all connectors I would lower their resistance and prevend them from overheating, is that it?
According to the wiring diagram for the 02 model, the ignition fuse is 20A.
You're right, I was thinking of the signal fuse, not the ignition one. So I guess you've debunked my theory ahah, nothing to do with fuses
Here's how the fuse box was (25A fuse on 10A signal)
