The correct way to check a Banshee coil is to connect 1 lead from your meter to EACH one of the spark plug wires and see what you get.Check your magnets in the flywheel to see if they are ok, check the air gap on the pickup coil, it should be .017 inches or about the thickness of a matchbook cover. Ohm out the stator, pickup coil, and the coil, if they all check out, then borrow a CDI box from a buddy and see if it will run. According to the Yamaha manual, there is no way to check the CDI box, except by substituting another.You should also check the spark plug caps on the coil, they have a resistor in them that can go bad.

Overboost Posted April 22, 2010 Report Share Posted April 22, 2010 ok so i installed the new coil and cdi box .... still no spark .... check stator and its ohms out within specs no problem...and the pick up coil also is within specs.... idk what to do.... no worries,I fixed it for him.....just outta tune was all....

Do you need special plug caps or will anyone from an auto parts store work? Quote Link to comment Share on other sites More sharing options...
