above lockout and should read zero ohms with an ohmmeter across pins 3 and 4. If not at lockout test the lift switch and contactor.

4.1.6. Early Lockout

It is very important that the instrument is installed so that its pins are reading the true battery voltage. Any voltage drops caused by long lines, switches, fuses, or poor connections will be seen by the instrument as a deeper discharged battery. 1.To check for voltage drops use a voltmeter with its positive lead on the battery’s positive terminal and the meter’s negative lead on pin 7 or 8 (whichever pin B+ is connected to). Load the battery and record this measurement. 2.Repeat this procedure with the voltmeter’s positive lead on pin 5 and its negative lead on the battery’s negative terminal, and record the voltage measured. 3.Add the two voltage readings. This total should be less than 1 percent of the nominal battery voltage. Voltage higher than this will cause the instrument to calculate battery state-of-charge from incorrect readings.

4.1.7. LEDs Do Not Light

The battery discharge indicator LEDs are illuminated by the keyswitch, pin 2. Verify that battery voltage is present across pin 2 and pin 5. 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 7 or 8 and pin 5. 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 2 must be on at B+, pin 7 or 8 must be connected to B+, and one or both of the hourmeter lines must be active. If the key switch is on, one or both inputs are correct, and the hourmeter icon does not flash, the instrument is defective.

4.2.3. Hourmeter Glass Icon Always Flashes

When the icon is flashing, the hourmeter is accumulating time. Turn the truck’s key switch off. This should remove voltage from pin 2 of the instrument. Should voltage be present at pin 2 and the hourmeter’s icon continues to flash, the instrument is defective.
