my friend brought this old dirt bike home from his farm its not an mx 125 yamaha but something similar but a street legal version. anyways it has no spark ive checked for power going into the coil but there is hardly anything like a reading of 6 on 200 mv. it has points so im not to familiar with them but it seems like theres not enough voltage to the coil. the point just kinda time the electricity for the coil to fire at tdc? am i on the right track? here a diagram to help
