Replacing a damaged charging coil in a 1987 Yamaha Moto 4 YFM200.
The symptoms that led to finding the bad coil were abnormal resistance readings, as well as very weak/no spark when starting with electric start. Pull starting did however work and engine would run.
The replacement charging coil was available by RMStator, really great price, cheap and fast shipping. Would highly recommend.
