[A] CHECK POWER SUPPLY. 1) Disconnect ignition coil harness connector. 2) Turn ignition switch "ON". 3) Check voltage between terminal (a) and ground. Voltage: Battery voltage
N.G.
Check the following. - Harness connectors F34, M36 (L.H.D. models) - Harness connectors M11, E104 (L.H.D. models) - Harness connectors F10, E15 (R.H.D. models) - Harness continuity between ignition coil and ignition switch. If N.G., repair harness or connectors.

CHECK GROUND CIRCUIT. 1) Turn ignition switch "OFF". 2) Disconnect resistor harness connector. 3) Disconnect power transistor harness connector. [B] 4) Check harness continuity between terminal (b) and terminals (c), (i). Continuity should exist. [C] 5) Check harness continuity between terminal (h) and engine ground. Continuity should exist.
N.G.
Repair harness or connectors.
