APPENDIX
MULTIPLE BATTERY SYSTEM TESTS
6 Volt Battery Test
Using Two 6 Volt
Batteries In Series
(12 Volt System)
NOTE:
Regardless of the conguration all Six Volt Batteries
are checked and load tested individually using the
6 volt scale. Follow battery load test procedure on
page 9.
6 VOLT BATTERY LOAD TEST
CONTROLS AND FUNCTIONS
TIMER LIGHT:
A green LED illuminates to indicate that the timer is on.
15 SECOND TIMER BUTTON:
Push to start the 15 second timer. This is used as a visual aid
only, in order to determine a timed 15 seconds. This does not cancel the
load automatically.
LOAD KNOB:
Turning the knob clockwise turns the fan on and controls the
amount of load during the test. The load knob is equipped with an auto
unload feature. The knob requires the user to hold the knob in the loaded
position. If you let go of the knob, it will spin back and cancel the load.
FAN OVERRIDE ON LIGHT:
Indicates when the fans override switch is on.
FAN OVERRIDE SWITCH:
The fan normally goes on automatically when the load knob is
turned on and when released the fan turns off automatically. In repeated
tests it is suggested that the fan override switch be turned on. This keeps
the fan on for better cooling.
In heavy duty applications, 6 and 12 volt charging systems are created
by combining 6 and 12 Volt batteries in various combinations.
For a valid test, batteries must be tested individually, and the charging
system must be tested at its rated voltage (6 or 12 Volts).
CAUTION: Care must be taken when disconnecting battery cables to
prevent shorting of loose cables to ground or positive. Arcing caused by
shorting cables can ignite hydrogen gas found in batteries and cause an
explosion.
The proper way to prevent arcing at battery is by disconnecting the
ground cable at the chassis or engine block and preventing it from
contacting any metal. Then the remaining cables can be disconnected
safely at each battery.
WARNING: Be sure load is off before attaching or removing load clamps
to prevent arcing and potential explosion from battery gases. Always
shield eyes and keep sparks, ames or cigarettes away from batteries.
