Complete loss of electrics whilst riding

[Pickle]

Glad you found it
Electrics are a pain.
Is it the ignition wires your talking about?
You say your going to try and get it out and solder it, can I suggest if it's goosed, you might be better 'adding' new wire to it, using heat shrink for each wire, then wrapping the whole lot in amalgamation tape this will also add a wee bit of slack that could help in the future.
I use a bit of cable tubing round the wires at the front, cheap as chips but saves this sort of hassle as like you, I use the steering lock alk the time.

Yes Sinto, its the group of five feed wires coming out of the bottom of the ignition barrel. They have the usual black plastic sleeving over them but it's cracked due to flexing and I suspect one or two of the wires inside are broken. Good suggestion about adding wire to give more slack.
I just hope it is a broken wire or two that can be easily fixed because buying and fitting a new barrel would put me off the road for weeks just as the weather is getting nice.
