19.4 Power Supply
19.4.1 Overview
Power supply systems may include batteries, charger/regulators, and charging
sources such as solar panels or transformers. All of these components may
need to be checked if the power supply is not functioning properly.
Section 17.4.3 includes the following flowcharts:

Adjusting Charging Circuit
If all of the power supply components are working properly and the system has
peripheral(s) with high current drain(s) such as satellite transmitter, verify that
the system’s power supply provides enough power. For more information,
refer to our Power Supply product literature or Application Note.
19.4.2 Troubleshooting at a Glance
Symptoms:
Possible symptoms include the CR1000 program not executing; Low12VCount
of the Status table displaying a large number.
Affected Equipment:

Likely Cause:
Batteries may need to be replaced or recharged; charger/regulators may need to
be fixed or recalibrated; solar panels or transformers may need to be fixed or
replaced.
Required Equipment:
