TM 9-2350-261-20-1 1. Check batteries to make sure they are fully charged(TM 9-6140-200–14).2. Turn off all electrical equipment/loads.CAUTIONIf voltage climbs above 33 or more volts,shut off engine. Alternator could bedamaged.3. Adjust rheostat to maximum resistance.4. Connect diagnostic test harness leads 1 and 4 together.5. Start engine and run at 800 rpm and lower resistance.6. Does voltage rise above battery voltage (test harnesslead 3 to ground) to approximately 28 volts?1. Remove alternator test kit (page 3-64.1).2. Replace voltage regulator (200 amp generator)(page 9-40).3. Repeat charging system operational check(page 3-64.4).1. Remove alternator test kit(page 3-64.1).2.
