    Arghhhh I've just killed my coil

    I left the key on all afternoon and cooked the coil on my Z200, so bad that it has melted the wires

    its the best weather for months and I have to ride home in a cage

    so can anyone help me with a coil for a 1979 Z200 or tips on how to test it?

    If its not sparking, its most likely the coil. I think a 79 bike may still have points not a cdi, so you could check the points are opening and closing with a standard voltmeter. You may have been unlucky - if the points had been open, leaving the key on would have been OK.

    Checking a coil is quite tricky - you can measure the resistance of the windings, but often they are OK on the bench and only fail at high voltage.

    the coil is shagged

    it had smoke coming out of it, no continuity over either primary or secondary.
    Oh, its a points model.

    I may have lined up one locally

    Don't try and run it with melted wiring. Replace and solder in some new wires and see what happens.

    Soldering in new wires is not a hard job just a bit fiddly and timeconsuming, depends on how bad the melt down is really. Before you start have a think about what needs to be covered by heat shrink and whether you have the necessary tools like a heat gun to do all this.

    If it fires up after the new wires are in I would imagine you are going to be ok with your existing coil.

    Unhappy

    it was definatly the coil, the smoke was coming from around where the ht lead goes into the coil itself, and there was plasticy gunk bubbling out from around where the low voltage wires go in

    you must have a flash as car.....
    the ones on your car probably just crap out when you have no cash, I killed mine by overheating it and melting the insulation inside I think

    Yeah always keep some old bolts or stones or something heavy in your wallet. If the car knows you are skint it will break down instantly !
