Ignition and Electrical System Service Chapter #15

Ignition System Service Performing a Spark Test Analyze plug Cleaning plug Gapping plug Plug installation – anti seize

Magneto Service Most components can not be serviced Inspect flywheel (key) Test magnet – should hold an ½” socket Air gap between module and flywheel Disconnect kill switch wire and recheck Some manufactures give directions to check resistant of module and wires – some suggest tell you to replace with known good unit

Servicing points Servicing Battery Ignition Systems Distributor Service

Battery Service Covered in earlier lesson Cause of failure Charging – Storage – Jump starting/jump pack

Checking Starting and Charging System Circuits Inductive amp clamp – Charging (alternator) output & starter draw Maintenance – Brushes – Diodes – Rectifier
