Check stator as follows:
(1) Connect multimeter to each set of stator leads and check for continuity. Standard stator coil resistance
is 0.402 ohms. If there is no continuity, stator coil is open and stator must be replaced.
(2) Connect multimeter from stator lead to stator frame. If there is continuity, stator core is shorted to ground
and stator must be replaced.
Check rectifier as follows:
(1) Check positive side diodes by connecting multimeter positive test probe to each stator terminal and nega-
tive test probe to BAT terminal. There should be no continuity. Reverse test probes. There should be con-
(2) Check negative side diodes by connecting multimeter positive test probe to each stator terminal and neg-
ative test probe to terminal E. There should be continuity. Reverse test probes. There should be no conti-
(3) If any diode is found to be bad, replace rectifier.
When soldering leads, use solder (SN60WRAP2), a 572 to 662°F (300 to 350°C) soldering iron (gun), and
complete each solder joint within 5 seconds. Use long nosed pliers or equivalent to allow for heat dissipation.
Connect regulator (29, FIGURE 3-49) to brush assembly (28) and solder all connections.
Press bolts (27) into brush assembly (28) and regulator (29). Pressure required is 221 Ibs (100 kg).
Connect rectifier (26) to brush assembly (28) and solder all connections.
Connect stator leads to rectifier (26) and solder all connections.
Mate stator (25) with end cover (24) aligning benchmarks.
