- Ignition OFF, measure the voltage across the battery terminals. The voltage should read 12.0 volts or greater at room temperature.
- If not within specified value, refer to Battery Inspection/Test .
- Connect a carbon pile tester to the battery.
- Start the engine and turn all accessories off. Observe the voltage reading on the tester. The voltage should read between 12.6-15.5 volts.
- Adjust the carbon pile tester so that the 12 volt current on the accessory DC power control module data list is reading 175 amps.
- If not within specified value, replace the accessory DC power control module.
