I cant get a spark on my moto4.does anyone know how much resistence I should have on the coil,magneto and pickup coil?If there is an easy way to check any of this stuff please let me know.I'm not real good with my voltage meter.also when the key is turned on should there be an electical current to the coil or should there not be one until the motor is turned over.I can work on 4-wheelers but I'm really ignorant when it comes to electrical wiring so any suggestions would be appreciated
