Ok i have an 81 Cb250N
the ignition got smashed & the wires yanked out ....i have found a new ignition switch but it hasnt arrived yet, i kinda need to use the bike so i thought i would hotwire it...
i got the old ignition switch, figured out what wires need to be attached to what, i have lights on the dash & the bike turns over but i have no spark !!!
i have replaced the main fuse, all switches are in the right place, all wires joined properly, but no spark ... i know this because i took out a spark plug to confirm it ...

the bike was running perfectly before the ignition incident, now no spark

is there a fuse i am missing? or does something like this (wires touched incorrectly maybe?) blow up the sparking unit?

this is urgent please.. i had planned on using the bike to go to work tomorrow

help help help help help pls pls pls pls

is it still points?? or had they changed to cdi by then??
it might be something to do with the kill switch
