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).
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 1 or 5 and pin 2. A voltage less than 2.0 volts per cell is required to bring the gauge indication downwards from a full reading. 4.1.4. LEDs Do Not Light The battery discharge indicator LEDs are illuminated by the keyswitch, pin 6. Verify that battery voltage is present across pin 6 and pin 2. If voltage is present and the LEDs do not light, the instrument is defective.
4.2. Hourmeter 4.2.1. No Display The LCD of the hourmeter will illuminate when power is applied at pin 1 or 5 and pin 2. If battery voltage is measured across these pins and the LCD does not turn on, the instrument is defective. 4.2.2. Hourmeter Glass Icon Does Not Flash If the icon does not flash, the hourmeter is not accumulating time. The key switch pin 6 must be on at battery positive, pin 1 or 5 must be connected to battery positive, and one or both of the hourmeter lines must be active. If the key switch is on, 162
