APU Generator Terminal B.
o
After testing lead 62 of the generator plug of the APU voltage
regulator, a correct voltage reading was indicated.
You test
lead 62 of the battery plug on the APU voltage regulator by
probing  through  the  insulation  of  lead  62  of  the  voltage
regulator  battery  plug  with  the  multimeter  red  probe  and
grounding the black probe.  The meter reading must indicate 24-28
vdc.  If not, replace the voltage regulator.  If correct voltage
was  indicated,  then  lead  62  from  APU  voltage  regulator  to
batteries requires repair or replacement (Figure 30).
