Serious warning

(1/2) > >>

I felt I should share a scary experience with you because I don't want it to happen to anyone else.

Basically, whilst going round a corner in the dark last night all of the electrics went out, lights, engine, etc.  It was a very dark, rainy night and there was no moon or streetlights to help.  Luckily for me I knew the road well and wasn't going too fast and there were no cars around so I managed to blindly get round the bend and stop safely.  If it had been a sharper corner I would have ended up in the hedge.

On inspection the fault turned out to be with the ignition switch.  The barrel seems to have become worn because when I wiggled the key everything came back on again.

I would say that anyone who hasn't replaced their ignition switch recently should have a look.  Switch the bike on then apply slight pressure to the key.  If it goes off you will see what I mean.  This is obviously very dangerous and until last night the switch had seemed perfectly ok so be warned.

On my 500, the solder connection on the back of the ignition switch fractured. Similar results.

Tried everything to solder it back on but ended up with a new switch.

Thanks Steve, I'm going to look at it today, probably replace it with a toggle switch for the time being until I can get the proper part.  Luckily for me 500/4s in a condition like mine are not really a target for bike thieves.  Having said that someone did try to hot wire it once and messed up all of my coil wires; so annoying.

Huzzah, I have found an old ignition switch from an Austin A35 which will be just the job!

Re-use is more efficient than recycling after all ;)

Bryanj:
Thatl do it as long as you dont want to leave it with side lights on----which i always thought was a damn stupid idea anyway
