As loads are placed on the bus, t
he ammeter
and voltmeter
s
hould
indicate the
current, and
output
volts.
NOTE:
The voltmeter may read as much as 1 volt higher than actual
buss
voltage
when
t
he un
it
is
fully loaded
,
as the
load is reduced, the meter will read more accurate. Current is limited
to
25 or 50 amps, depending on model.

to the other position.
4). As the battery charges, amps will decrease as
voltage increases, battery is fully charged near
14 or 28
volts,
depending on model. Current should be one amp and lower. Charger can be left connected
indefinitely
without damage to battery.
5). To discontinue,
flip the power switch
