BT GENERATOR TROUBLESHOOTING
f, Should the voltag, drop below the proper rate, loaded
excitation can be increased to raise this voltage by
repositioning connections on the VoltagelHertz
Connection Bar. Repositioning the two leads (red/white
and yellow/white) from (1) to (2) or (3) terminals will
increase the loaded voltage out progressively in tha(
order.
NOTE: No-load voltage may be effected needing read-
justment with the compound transformer. Do not use
these adjustments to compensate for overload condi-
tions being placed on the generator/engine (inductive-
motor type loads). Loss of generator hertz/speed, the
result of overload, will cause a drop in voltage output.
