(1) Connect the negative (-) terminal of the 1.5 V power supply
to terminal (4) of the ignition power transistor; then check
whether there is continuity between terminal (11) and termi-
nal (4) when terminal (1) and the positive (+) terminal
are connected and disconnected.
NOTE
Connect the (-) probe of the circuit tester to terminal 11.

Primary Coil Resistance
Measure the resistance between connector terminal (3) (pow-
er) and each coil terminal.
Measuring point:
Coil A (No.l-No.4 cylinder side coil) . . . . . . (2)-(3)
Coil B (No.2-No.5 cylinder side coil) . . . . . . (l)-(3)
Coil C (No.3-No.6 cylinder side coil) . . . . . . (4)-(3)
Standard value: 0.67-0.81 Sz
TSB Revision
Secondary Coil Resistance
Measure the resistance between each coil high voltage termi-
nals.
Measuring point:
Coil A (No. l-No. 4 cylinder side coil)
Coil B (No. ~-NO. 5 cylinder side coil)
Coil C (No. ~-NO. 6 cylinder side coil)
Standard value: 11.3-15.3 Wz
