Use a circuit like the one shown in Fig. 8-7 for measuring XC output. A hot plate or lamp Lvith a power factor of 1 .O ma>-
be used as a load. Adjust the load and rpm. and check that the voltage range 1s as
specified
in Table

Switch the powr on. Khen 1.45R resistance is attached as a load. check that the voltage is within the 13 to 1 IL7 range.
NOTE:
If a battery
is connected
as the load, the output
voltage increases by about
7 TO ZV, possibly
causing battery
over-
charge.
Control
battery
liquid
level during
charging
to prevent
overcharging.

MEASURING
INSULATION
RESISTANCE
Connect a meger tester to one of the two receptacle output
terminals and the ground terminal. then measure rhe insula-
tion rssistanx.
An insulation resistance of 1 megohms or
more is nxmal.
(The original insulation resistance at the
time oishlpment from tht factor! is 10 megohms or more.)
Ji it is I?ss than 1 mqohm. disassembl? the generatnr and
measure the insulation resistance of the statOr. rotor and
