24 VOLT SYSTEM TESTING
The 42HD was designed for testing 24 volt systems. The load
leads can be connected directly to 24 volts to power the tester.
Additionally a load of up to 150 amps can be applied to verify the
operation of the charging system. Since most 24 volt systems
are made up of two 12 volt batteries, be sure to test each battery
separately for an accurate test.
INDICATOR LIGHTS
Amps Ripple
The Amps Ripple indicator will illuminate when AC ripple is de-
tected from the alternator.
Load On
The Load on Indicator will flash and the beeper will sound one
time a second to help time the load test. After 16 seconds, the
beeper will sound continuously indicating the end of the load
test.
Load Limit
The Load Limit Indicator will turn on when you are approaching
the load capacity of the carbon pile.
Hot (Do Not Load)
When this light turns on, do not apply a load. Let the Fan run to
cool down the carbon pile.
SAFETY PRECAUTIONS
—Read All Instructions Before Using The Meter—
• Always wear eye protection when testing vehicles. Be extra
careful near batteries and moving parts. Do not lay tools on a
battery.
• Battery gas is highly explosive.
a. If a battery explodes flush the acid away from persons skin with
generous amounts of water. Follow up with a neutralizing solution
of baking soda and then more water.Treat clothing, vehicle parts,
and equipment similarly. Any acid traces inside equipment must
be removed by generous rinsing. Dry equipment and place in a
warm 50°C (120°F) oven until thoroughly dry.
b. Never use a wrench on the ungrounded battery terminal until
the grounded one has been disconnected. Contact between
the vehicle body metal and the hot terminal can cause sparks to
ignite gas or even weld tools into a battery short circuit.
c. Keep the space around a battery well ventilated.
d. Do not make sparks or allow flames near batteries.
• Before working on a vehicle set the brakes and block the
wheels. Beware of automatic parking brake releases.
• Keep your work area well ventilated and free of exhaust.
Engine exhaust contains deadly poisons. Treat Gas
Detector exhaust and drain hoses the same as the vehicle
tailpipe. Both give off deadly exhaust fumes.
• Avoid electrical shocks caused by getting close to live ignition
wires or touching the coil TACH terminal. A person’s reaction
near a live engine can be more damaging than the shock.
• Keep spark producing devices at least 0.5m (18”) above the
floor to reduce the hazard of igniting gasoline vapor.
• Do not let test leads wind up in a moving fan or pulley. Route
leads away.
• Remove finger rings and metal wrist bands. They can short
terminals and become very hot from electric current.
