Mitsubishi Montero (1991+). Manual — part 43

1) Disconnect power transistor connectors. Using a DVOM,

connect positive ohmmeter lead to terminal No. 2 and negative lead to

terminal No. 7. See Fig. 7. Ensure there is no continuity.

2) Using a 1.5-volt dry cell battery, connect positive end of

1.5-volt battery to power transistor terminal No. 8 and negative end

to terminal No. 7. DVOM should now read continuity at power transistor

terminals No. 2 and No. 7. Replace power transistor if it does not

test as described.

MAGNETIC & OPTICAL IGNITION

Ignition Coil Resistance

1) Using a DVOM, measure primary coil resistance between

positive and negative terminals of coil. See Fig. 9. For ignition coil

terminal identification See Fig. 11 - 13.

2) Measure secondary coil resistance between coil positive

terminal and ignition coil tower. See Fig. 10.

3) Primary and secondary coil resistance should be within

specification. See IGNITION COIL RESISTANCE table.
