BLACKOUT RELAY provides power to the following
system:
• Rear Differential Solenoid
CHARGING SYSTEM
Current Draw - Key Off
Connect an ammeter in series with the negative battery cable.
Check for current draw with the key off. If the draw is excessive,
loads should be disconnected from the system one by one until
the draw is eliminated. Check component wiring as well as the
component for partial shorts to ground to eliminate the draw.
Charging System “Break Even” Test
The “break even” point of the charging system is the point at
which the alternator overcomes all system loads (lights, etc.)
and begins to charge the battery. Depending on battery condition
and system load, the break even point may vary slightly. The
battery should be fully charged before performing this test.
