connected to a fully charged battery and allowed to track its
discharge without break in power.
4.1.3. No Discharge, Gauge Does Not Run Down
The instrument monitors loaded battery values. When
connected to a partially discharged battery the gauge will not
run down until it observes that the loaded values of the
battery are at or below gauge current state. A working time of
at least 30 minutes is required for the gauge to run from full to
empty.
To verify that the instrument will run down, measure across
pin 7 or 8 and pin 5. A voltage less than 2.0 volts per cell is
required to bring the gauge indication downwards from a full
reading.
4.1.4. No Lockout
The LED display must be alternately flashing the two left-
most red LEDs for lockout to occur.
The J output functions like an SCR. At lockout, pins 3 and 4
will open as long as lift is inactive.
To test this output:
1. Remove the wire leading to pin 3 when at lockout.
2. Replace the wire, and then try to lift. If the lift ceases to
operate the instrument is good, but there is a leakage
current somewhere in the lift circuit.
3. Check across the lift switch. After replacing the wire, if
the lift operates, the instrument is defective.
4.1.5. No Lift
First, verify that the gauge is not at lockout with its two red
LEDs alternately flashing. The relay outputs should be closed
NOTE! New instruments are shipped from the factory
with a full reading in their memory. The first
time the instrument is connected to the
truck’s battery it will always show a full
charge. It is either resetting to full because
the battery is fully charged or if the battery is
not fully charged it is repeating the
information in its memory which is a full
reading (typical 10 year battery life).
