I turned the pedals and the voltage dropped by around 5 volts every time it passed a magnet. Whilst it was upside down I turned the pedal faster , and it...

    Yes there is a sensor on teh front fork and a magnet on the front wheel, here is also a sensor on the frame by the pedals and 4 magnets on the inside of the pedal sprocket that holds the chain. Should I test these in some way?

They all read 13 or 14 volts with ignition light on. When light went off the output from all three...

    Hi thanks for taking the time to try and help. I have checked the battery box with my meter, All three batteries are linked in series and each one is giving out over 12 volts (around 13/14). Cant check the total output as it only goes up to 18 volts , dont want to blow meter up.

    Its a Classic, no model lisetd on it anywhere. The batteries were purchased new a couple of weeks ago from the local Battery Supplier. HE did run a test on them when he fitted them in the battery holder.
