Activation Conditions
Battery voltage at the MSM or PM is greater than 17 VDC.
Unit Behavior
Shutdown and alarm.

Corrective Actions
1. Check Battery Voltage a. Test voltage at battery with unit off. Must be between 11-16 VDC. b. Test voltage at battery with unit running. Must be between 12-16 VDC. NOTE Voltage with unit running should always be higher than voltage with unit off due to battery charging. 2. Check Alternator Voltage a. Test voltage at PM-ALT+ with unit off. Must be between 11-16 VDC. b. Test voltage at PM-ALT+ with unit running. Must be between 12-16 VDC.
