INCORRECT
REGUTATOR
VOTTAGE
SETTING
cAUTION:
Do not short
across any
of
the terminals
in
the
junction
box.
To
check
the voltage
setting reconnect
all connections
and
then
connect
the
positive
voltmeter lead
to the regulator
{rBAT"
terminal
and
the negative
lead
to
ground.
(Fig.
35).
Turn on
the switch but
do not start
the engine.
3.
The voltmeter
should read battery
voltage.
4. A zero
reading
indicates
an
open in
the
circuit
between
the regulator
and
the battery.
If
green
"on
light" lights up on
the dash
the
open
circuit
would be between
the
key switch
and
regulator.
If
ignition
coil had current
the
open would be
from
the
red wire
to the field
to
regulator.
5"
If the voltmeter
reads battery
voltage, operate
the engine
at
1500
rpm
for
2A minutes with
the cover
on
the regulator and
all
accessories
turned
off
to
bring
the regulator
to
operating
temperature'
For accurate
RPM readings use the
Merc-O-Tronic
Electronic
Service
Tachometer.
6. Turn off
the ignition
switch
to stop the engine.
7, Restart
the
engine, operate
it at 1500rpmand
note
the
voltage
setting.
8. The dash
ammeter
must show a chatge
of not over
10 amperes
at
the
time
the
voltage
setting
is read.
