Question about 2003 Beta Jonathan 350
I have a beta 350 that has no spark at all to either cylinder. I don't know the history of this bike
It was given to my dad recently after sitting up for a while. The battery spins the bike over fine but shows a little weak at 12.1 volts. I have ohmed the pulse generators at the 4-pin connector under the tank. They ohm'd a little low at around 430 (I think going from memory here). I don't know if this is too much out of range for them to function properly. I know the spark units are supposedly untestable but I have popped them apart and I'm not seeing ANY DC voltage coming into either of them on ANY wire with key on, or while cranking. Shouldn't these have some sort of voltage coming to them at some time? If not, how else can they function. Also, don't have any voltage to the coils, but I assume this is because the CDI's aren't sending any. The coils ohm fine, and I have connected them to my race car and spun it over, and they are fine. They throw a nice blue flame from both terminals. Any ideas where to go from here? I thought the CDI's may be bad, but not sure at this point. They may be just not getting power for some reason. ,starter!,,,
