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.
