5.
Using ohmmeter set to lowest range, test three
positive diode wire assemblies (50, Figure 4-13).
Touch one test wire to the positive diode casing
and the other wire to the terminal, then switch
test wires. Meter should indicate one high and
one low reading. Replace three positive diode
wire assemblies (50) if readings are the same.
6.
Using ohmmeter set to lowest range, test three
negative diode wire assemblies (79, Figure 4-
14). Touch one test wire to the negative diode
casing and the other wire to the terminal, then
switch test wires. Meter should indicate one high
and one low reading. Replace three negative
diode wire assemblies (79) if readings are the
same.
