Question about 2003 Yamaha YZ 250
You should install a rectifier/regulator.
It's a small cast aluminium block, with a 4wire-connector:
2 to the charging coil ( where you measure 2*7volts ) 1 to the frame ( black ) and 1 wire to your main circuitry ( red )
You can take it from any 12v motorcycle. Sometimes, the aluminiumcasing is the ground ( no black wire ). Check that you allways have a good connection to the frame ( grounding ) in both cases.
