My 2005 Ram 1500 battery loses charge when not used for a while.
With dome light fuse removed, opening passenger doors causes a 1.25 amp draw for several minutes, then it drops to 60 mA forever. The 1.25 amp draw goes away when the radio/cluster/hood light fuse #51 is removed. I tried temp disconnect the upgraded radio and the 1.25 amp draw remained. Perhaps this is something in the "cluster"? No under hood light option installed.
I replaced battery with new high dollar AGM battery and when engine running charges nicely above 14 volts. Battery has about 13.5 volts immediately on standby with the engine off, but soon drops below 12 V and below. All wiring and grounds check OK.
I would not think 60 mA would drain the battery down so quickly. I have bought a VDC BatteryMinder to keep connected as this truck is only used for camping a few times each year. Camper battery is disconnected. The big issue is when camping in wilds and it won't start!
