DIODE ASSEMBLY
- Using ohmmeter, check each diode for continuity. If resistance or continuity exists in both directions, diode is faulty. If any diode is defective, replace complete rectifier assembly.
- Diode trio is okay if continuity exists in one direction only. If continuity exists in both directions, replace diode trio.
OVERHAUL
Note. (Scheme 7)for exploded view of Hitachi generator. (Scheme 8)for exploded view of Mitsubishi generator.
To remove a stuck rear cover after removing case bolts, use soldering iron/gun to heat rear cover bearing housing to about 122-140°F (50-60°C). This action will expand housing enough to slide cover off rear rotor bearing. Ensure spring washer located in rear cover bearing bore is not lost during disassembly.
