NOTE: After checking junction block connector D-06 and D-08, 
check the wires. If junction block connector D-06 and D-08 are 
damaged, repair or replace them. Refer to GROUP 00E, Har-
ness Connector Inspection 

P.00E-2

.

Q: Are the harness wires between combination meter 

connector C-04 (terminal No.24) and ignition switch 
(IG1) in good condition?
YES : Go to Step 9.
NO :  Repair them. The tachometer should work normally.

STEP 9. Check the circuit at ignition power transistor 
connector A-05.

(1) Disconnect connector A-05 and measure at the harness 

side.

(2) Turn the ignition switch to the "ON" position.

(3) Measure the voltage between terminal 5 and ground.

• Voltage should be four volts or more.

(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Does the measured voltage correspond with this range?

YES : Replace the ignition power transistor. Then confirm 

that the malfunction symptom is eliminated.

NO :  Go to Step 10.

STEP 10. Check ignition power transistor connector A-05 
for loose, corroded or damaged terminals, or terminals 
pushed back in the connector.

Q:  Is combination meter connector A-05 in good 

condition?
YES : Go to Step 11.
NO :  Repair or replace it. Refer to GROUP 00E, Harness 

Connector Inspection

. The tachometer 

should work normally.

STEP 11. Check ignition power transistor connector A-05 
and combination meter connector C-05 for loose, corroded 
or damaged terminals, or terminals pushed back in the 
connector.

Q: Are ignition power transistor connector A-05 and 

combination meter connector C-05 in good condition?
YES : Go to Step 12.
NO :  Repair or replace them. Refer to GROUP 00E,
