Check Battery Current
electrical
Description
With all circuits off, 12 VDC current flow is more than +1.5 to -2.0 amps, and pretrip fails with “PRETRIP FAIL AND COM- PLETED”.
Activation Conditions
With all circuits off, current flow of more than +1.5 to -2.0 amps is detected in the 12 VDC electrical circuits. NOTE If this alarm occurs, Pretrip Test #2 will be skipped and Pretrip Test #3 will start.
Unit Behavior
Engine and Electric Operation: Pretrip will fail and display “PRETRIP FAIL AND COM- PLETED”.
Reset Conditions
Auto reset if Pretrip is started again, or alarm may be manually reset using the display mounted keys or by turning the unit off, then back on again.
Corrective Actions
1. Check DC Current Draw and Sensor Observe current draw reading in unit data. Reading must be between +1.5 to -2.0 Amps. 2. Check Individual Circuits - Isolate individual circuits and test amp draw. Must be in range. (Refer to Section 2.12 for correct electrical values.) 3. Check For Parasitic Loads - Check for electrical loads that are drawing current with all circuits OFF. Check for non-factory installed devices such as lift gates, inside lights, satellite systems, etc. These devices must be wired so as to not draw current during Pretrip testing.
