Before condemning a rotor for an open coil, check the solder joints at the slipring leads, as

a poor connection at either of these leads will cause the same test result as an open coil, If the proper

resistance is not obtained after resoldering these connections, replace the rotor.

g. Stator Test.

Replace any stator that appears overheated (discolored) or that has charred insulation,

regardless of how they test. Perform continuity and ground tests as follows:

NOTE

Do not test the stator while it is connected

to the heatsinks. Remove the stator from

the alternator before testing.

(1)

Check for continuity by connecting a 115-vat test light to each of the lead combinations in

figure 5-22. If the lamp fails to light in any combination, replace the stator.

Figure 5-22. Stator Continuity Test.

(2)

Check for a ground by connecting the 115-vac test light as shown in figure 5-23. If the lamp

lights, replace the stator.
