(TM 9-2320-361-10) and

observe multimeter.

Test 5. Test starter motor solenoid

contact voltage drop.

1. Set multimeter to voltage

range that will measure

tenths of a volt.

2. Connect multimeter between

starter motor solenoid

terminal lugs 2 and 3.

NOTE

A voltage reading exceeding 0.4 volts

indicates defective starter motor

solenoid.

3. Crank engine

1. Replace starter motor and solenoid

(TM 9-2320-361-10) and

assembly (WP 0088 00).

2. If malfunction still exists, go to

tests 6, 7, and 8.

Test 6. Test negative cable 7 voltage

drop from batteries to starter

motor.

1. Set multimeter to voltage

range that will measure

tenths of a volt.

2. Connect multimeter positive

lead to terminal stud on end

plate of starter motor and

negative lead to frame

ground.

NOTE

A voltage reading exceeding 0.4 volts

indicates defective starter motor

solenoid.

1. Replace starter motor and solenoid
