Also FYI, When your rig is plugged into 120 volt AC power, it is likely that the starting battery is not being charged unless the rig has had a device such as Trik-l-Start or BIRD installed. The starting battery powers a number of items such as the radio memory and carbon monoxide alarms as well as self-discharging which is common to all lead/acid batteries. A new healthy starting battery may start the engine after a 2-3 weeks with rig parked , a tired battery may not have enough oomph after a week or two. You can connect a smart charger like Battery Minder to starting battery to keep it fully charged but not over-charged. Letting any battery remain discharged/dead damages it and shortens it's useful life.
