TB 9-2350-368-25 4-2 NOTE M113A3 engines equipped with glow plug cold weather starting system can be tested. The glow plug indicator light is found in center of instrument panel on right side. Troubleshoot using applicable TM series. Both the 100 and 200-amp regulators come from the manufacture with a stick-on label listing the NSN, nomenclature, and output. They are look-alike and use the same case and electrical connectors; however, they cannot be interchanged in their application. Severe equipment damage will always result and personal injury can occur. The 100-amp regulator is located near the front of powerplant test stand. The 200-amp regulator is located near the rear of powerplant test stand. There is a definite size and weight difference between the 100 and 200-amp alternator when you look at the powerplant. The 200-amp alternator weighs approximately 80 lb. and looks almost twice the size of the 100-amp alternator. Always disconnect the batteries' ground cable(s) before removing or connecting cables to the regulator to avoid personal injury or equipment damage from the high amperage supplied by the batteries. It is not necessary to disconnect battery ground cables when connecting the powerplant harness to the powerplant test stand harness, just make sure the master switch is off.
