IGNITION COIL AND POWER TRANSISTOR

01L0838

OPERATION

Whenthepowertransistorunit is switched
ONbythesignalsfromtheenginecontrol
unit,the primarycurrent of the ignition coil
will flow.Whenthepower transistor' unit is
switchedOFFthe primary current flow is in-
terrupted, and high voltage is produced at the
secondary coil:

When the engine control unit switchesOFF
the power transistor within the unit, the bat-
tery voltagewithin the unit is applied to the
power transistor unit, and the power transis-
torunitisswitchedON;Inaddition,the
power transistor unit is switched OFFwhen
theenginecontrolunitswitchesONthe
power transistor within the unit.

Проверка

Using Multi-use tester (MUT)
Spark advance value
