STARTING MOTOR SOLENOID (PRESTOLITE) REPAIR - CONTINUED
0363 00
TESTING - CONTINUED
CAUTION
Before proceeding, wait three minutes for solenoid winding to cool. Do NOT allow test circuit to stay on
more than 15 seconds. Overheating will occur in solenoid and test results will be in error. Failure to follow
this procedure could result in damage to equipment.
NOTE
Readings from ammeter and voltmeter are to be recorded.
11.
Close knife switch to energize test circuit.
12.
Read and record ammeter indication.
13.
Open knife switch to de-energize test circuit.
14.
Check test result of recorded ammeter indication. If reading is 23 to 27 amperes, proceed to step 15. If reading is 0
amperes, solenoid winding is open (broken wire). Replace solenoid. If reading is 30 amperes or higher, solenoid wind-
ing is shorted. Replace solenoid.
CAUTION
Before proceeding, wait three minutes for solenoid to cool. Do NOT allow test circuit to stay on more than
