MALFUNCTION
TEST OR INSPECTION
CORRECTIVE ACTION
1. STARTER WILL NOT
CRANK (Contd)
Test 2. Test for battery voltage at lug
D of magnetic starter relay.
1. With power accessory switch
ON, turn start switch and at
same time, check for battery
voltage at lug D on starter
relay.
2. Set multimeter to RX 1 scale.
Check for continuity between
lug C on starter relay and
ground.
3. Check for battery voltage at
lug B of starter relay with
start switch turned.
4. Check for battery voltage at
lug A on starter relay. Voltage
should always be present.
5. Check continuity of lead 214
between lug B on starter relay
and pin 1 on starter solenoid.
1. If 19 VDC are not present, go to
test 4.
2. If voltage is present, go to test
step 2.
1. If continuity is 1 ohm or less, go to
test step 3.
2. If continuity is greater than 1 ohm,
disconnect ground lead at lug C.
Repair or replace ground lead
(WP 0090 00). Go to WP 0012 00,
table 1, malfunction 1, test 1, step
1 and retest.
1. If voltage is present, go to test
step 5.
2. If voltage is not present, go to test
step 4.
If voltage is not present, repair or
replace lead 14 (WP 0090 00). Go to
WP 0012 00, table 1, malfunction 1,
test 1, step 1 and retest.
If continuity is not present, repair or
replace lead 214 (WP 0090 00). Clean
connections before reinstalling lead.
Ensure all connections are tight. Go
to WP 0012 00, table 1, malfunction 1,
test 1, step 1 and retest.
