pen the chapagne!!!
Well after cooking the controller for an hour at gas mark 2 (actually gently heated with fan heater in the house!!) and renewing the wire from the battery to the fist bullet connector (wire was very corroded) the bike works!!
Lots of cheers and fireworks.
Will now seal all the connections and try to make some sort of shield for the wiring.
Just a thought as a Chemistry teacher is the high current going through these wires speeding up the corrosion?
I build and fly model planes and we have similar problems. Should the wiring be heavier gauge or replaced as a matter of course?
A million thanks to everyone who took the time to reply. I wiil keep you updated as to how things go.
One last question would there be any harm in keeping the new battery as a spare, does it degrade even if not used?
