Step 1. (Cont).
Set VAT-33 AMP. RANGE selector to the 0-100 ampere range.
Set VOLT RANGE selector to 18-40 volt range.
Move VOLT LEAD SELECT to EXT. position.
Move LOAD control to OFF position.
Install ammeter clamp around battery positive cable, arrow pointing
away from batteries.
Connect remote starter switch between BAT and S terminals on
solenoid.
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 2 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 2.
Disassemble starter (page 3-224).
Inspect bushings in drive housing and lever housing for dirty, worn,
or
a.
tight condition.
Clean dirty bushings (page 3-234). Replace defective bushings
and reassemble starter (page 3-240).
