FIGURE F.20 – DIODE LEAD REMOVAL
OUTPUT RECTIFIER BRIDGE TEST(CONTINUED)
9. Using the 7/16" wrench, remove the stator
leads and diode pigtail leads from the three
studs. Label the leads for reassembly.
Note leads and pigtail placement for
reassembly. See Figure F.20.
10. Electrically isolate the six diode pigtail
leads by carefully bending them out into
"free air."
11. With an ohmmeter or diode tester, check
each of the six diodes from their pigtails to
their respective heat sinks.
12. Reverse the tester leads and check the
diodes again. Diodes should have a low
resistance in one polarity and a very high
resistance in the opposite polarity.
13. Replace any "shorted" or "open" diode as
the tests indicate. See the Diode Removal
and Replacement Procedure.
14. Replace the pigtails and stator leads onto
the correct studs. Assemble the washers
and nuts.
15. Replace the lower front panel and output
leads.
16. Replace the upper control panel and
secure.
17. Replace the front left and right case sides.
