may
be used as a load. Adjust the load and rpm, and check that the voltage range is as specified in Table 8-1 at the rated amperage
and rated rpm.

Switch the power on: adjust the load to 8.3 A at the rated rpm, and check that the voltage is within the range of 13 to 11
V.
NOTE: If a battery is connected as the load, the ouwut voltage increases by about 1 to 2 V, possibly causing battery over-
charge. Control battery liquid level during charging to prevent overcharging.

MEASURING INSULATION RESISTANCE
Connect a megger tester to one of the two receptacle output
terminals and the ground terminal, then measure the insula-
tion resistance. (Ifyourgenerator is the no-fise breaker type,
close the no-fuse breakerand measure it. If yourgenerator is
the dual voltage type, any voltage receptacle may be used.)
An
insulation resistance of 1 megohms or more is normal.
(The original insulation resistance at the time of shipment
from the factory is 10 megohms or more.) If it is less than
1 megohm, disassemble the generator and
measure the
insulation resistance of tne stator, rotor
and control box
individually.
