SEF928V
Component Description
NGEC0812
IGNITION COIL & POWER TRANSISTOR
NGEC0812S01
The power transistor switches on and off the ignition coil primary
circuit according to the ECM signal. As the primary circuit is turned
on and off, the proper high voltage is induced in the secondary cir-
cuit. The distributor is not repairable except for the distributor cap
and rotor head.
NOTE:
The rotor screw which secures the distributor rotor head to the
distributor shaft must be torqued properly.
: 3.6±0.3 N·m (37±3 kg-cm, 32±3 in-lb)
ECM Terminals and Reference Value
NGEC0813
Specification data are reference values and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM’s transistor. Use a ground other than the ECM terminals, such as the ground.
