Mirage L4-1597cc 1.6L DOHC (1990)
2. Connect a power supply of 1.5v (one dry cell) between power transistor terminals 6 (+) and 3 (-).
3. Check for continuity between terminals 7 (+) and 3 (-).
Continuity
Should exist
4. Remove power from terminals 6 and 3.
5. Check for continuity between terminals 7 (+) and 3 (-).
Continuity
Should not exist
NO. 2 & NO. 3 COIL SIDE
1. Disconnect the power transistor connector.
Power Transistor (Ignition Coil 3 & 4) Test
2. Connect a power supply of 1.5v (one dry cell) between power transistor terminals 2 (+) and 3 (-).
3. Check for continuity between terminals 3 (-) and 1 (+).
Continuity
Should exist
4. Remove power from terminals 2 and 3.
5. Check for continuity between terminals 3 (-) and 1 (+).
Continuity
Should not exist
If the Power Transistor fails any of these tests, replace the Power Transistor.
IGNITION COIL
1. Disconnect the ignition coil connector.
Ignition Coil Test
2. Using an ohm meter, check the resistance between terminals 2 and 3. (The coils at 1 and 4 cyls)
Resistance
0.77 - 0.95 ohms
3. Using an ohm meter, check the resistance between terminals 1 and 3. (The coils at 2 and 3 cyls)
Resistance
0.77 - 0.95 ohms
