PART 2: ELECTRIC POWER SYSTEM 12-Volt DC System The ComfortClass System Batteries are located in the ComfortClass System Battery Box on the driver’s side of the vehicle behind the sleeper compartment. The four Deep Cycle AGM (Gel Cell) batteries power all electrical system components on the vehicle EXCEPT the starter motor. Starter Batteries Figure -49 Figure -46 Figure -47 CAUTION: Do not replace the Deep Cycle AGM (Gel Cell) batteries with common lead acid batteries. The ComfortClass System is designed to draw to very low voltages which will significantly reduce the life of a lead acid battery. Use only PACCAR recommended ComfortClass System Batteries. See your Peterbilt dealer for additional information. Figure -50 Figure -51 i PB00008 NOTE: The charging instructions can also be found on the top of the ComfortClass System Battery Box cover. Figure -48 i NOTE: Because the ComfortClass System Batteries power the engine controls and starter relay, you may experience a no-crank condition if the ComfortClass System Battery voltage is below 9.5-Volt, even though the Starter Batteries are fully charged. The Starter Batteries (two 1000 Cold Cranking Amp 12-Volt batteries) are located below the cab on the driver’s side of the vehicle. These batteries are used only to power the starter motor. A DC/DC charger serves to isolate the starting batteries from the ComfortClass System Batteries and provides charge to the Starter Batteries to maintain them at a minimum of 12 Volts.
