MALFUNCTION
TEST OR INSPECTION
CORRECTIVE ACTION
1. STARTER DOES NOT CRANK (Cont).
Step 3. (Cont).
Install ammeter clamp around battery positive cable, arrow pointing
away from batteries.
Connect remote starter switch between BAT and S terminals on sole-
noid.
Connect load leads to one battery only.
Perform remainder of test quickly to avoid overheating tester. Allow 60
seconds between tests to permit tester to cool.
Push in and hold button on remote starter switch.
Turn LOAD control until voltmeter indicates 20 volts.
Use hand-held tachometer to check armature speed. Record speed.
Record ammeter indication.
Turn LOAD control to OFF position.
Release button on remote starter switch.
Tachometer must indicate 5500 to 9000 rpm.
Ammeter must indicate 70 to 110 amperes.
a. If armature speed exceeds 9000 rpm and ammeter indication ex-
ceeds 110 amperes, there is short in field coil. Replace field
coil (page 3-224) then perform step 3 test above to check for
improvement.
b. If armature speed is less than 5500 rpm or ammeter indication is
less than 70 amperes, go to step 4 below.
c. If armature speed is within 5500 to 9000 rpm range and ammeter
indication is within 70 to 110 ampere range, starter checks
okay.
Step 4.
Disassemble starter (page 3-224).
Check if bushings in drive housing and lever housing are dirty,
worn, or tight.
a. Clean (page 3-234) or replace bushings as necessary. Reassemble
starter (page 3-240).
b. If bushings check okay, go to step 5 below.
