TESTING
1.
Test positive rectifier (35) as follows:
a.
Connect positive lead of diode tester to positive rectifier (35). Touch negative lead to each of three diodes (65).
High resistance should be indicated. If any of three diodes show low resistance, replace positive rectifier.
b.
Reverse test leads so that negative lead is connected to positive rectifier (35). Touch positive lead to each of three
diodes (65). Low resistance should be indicated. If any of three diodes show high resistance, replace positive recti-
fier.
2.
Test negative rectifier (36) as follows:
a.
Connect negative lead of diode tester to negative rectifier (36). Touch negative lead to each of three diodes (66).
High resistance should be indicated. If any of three diodes show low resistance, replace negative rectifier.
b.
Reverse test leads so that positive lead is connected to negative rectifier (36). Touch positive lead to each of three
diodes (66). Low resistance should be indicated. If any of three diodes show high resistance, replace negative rec-
tifier.
3.
Check capacitor (30) using ohmmeter with positive and negative leads connected to terminals. If resistance reading is
low, replace capacitor.
