IGNITION SIGNAL

IGNITION SIGNAL

PFP:22448

Component Description

UBS00E2I

IGNITION COIL & POWER TRANSISTOR

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 dis-
tributor shaft must be torqued properly.
