3-36. MAIN GENERATOR (cont)
Attach megohmmeter lead (1) to stator housing (2) and to each exciter lead.
Attach lead (1) of megohmmeter (4) to lead GF+ on stator housing.
Attach lead (3) of megohmmeter (4) to lead GF-on stator housing and note reading on megohmmeter.
Attach megohmmeter lead to each GF+ and GF-and stator housing.
Repeat steps g thru h for GS, GP, and GN leads.
Procedures specify the heating and cooling of parts to aid in disassembly and assembly. Heated and
cooled parts may cause injury to personnel if hand protection is not worn when handling. Wear protective
gloves for maximum protection.
If a reading of less than 3 megohms is obtained on two sets of leads, bake stator for 4 hours at 230°F (110°C)
in a convection oven. Recheck megohm readings after cooling stator to room temperature. If the readings
are still low, replace stator.
Perform a bar-to-bar resistance test by the following:
Place lead (1) of multimeter (2) on the shaft or core of the armature.
