MALFUNCTION
TEST OR INSPECTION
CORRECTIVE ACTION
18. HIGH GENERATOR OUTPUT VOLTAGE (NO LOAD).
Step 1.
Check for voltage regulator failure. Remove voltage regulator lead wire X39C16 from terminal 17.
If voltage goes even higher, the voltage regulator is good.
Test and repair defective regulator (paragraph 6-6).
Step 2. Check voltage adjust rheostat (R1).
Replace rheostat (Rl) if necessary.
Step 3. Check current voltage transformer (CVTI) (paragraph 6-9b(7)).
Replace bad transformer.
Step 4. Check transformer T2 (paragraph 4–38 (15), TM 5-6115-585-12).
Replace bad transformer.
19.
FREQUENCY METER (M3) FAILS TO REGISTER.
Step 1.
Check transformers T1 and T2 (paragraph 4-38 (14) and (15), TM 5-6115–585–12).
Replace bad transformers.
Step 2. Check frequency meter and transducer (paragraph 6-4).
Replace bad meter or transducer.
20. BATTERIES DO NOT CHARGE.
Step 1.
Check battery charging alternator stator (paragraph 7-8).
Replace bad stator.
Step 2. Check battery charging alternator rotor (paragraph 7-8).
Replace bad rotor.
Step 3. Check regulator-rectifier assembly (TM 5-6115-585-12, paragraph 4-27).
Replace bad regulator-rectifier.
