2011 rubicon 26,000 miles. over one year trying to find a dead battery problem . about every month or two i get a dead batt. over night. has new bosh battery, checked volt 3.77 . it is obvious to be a intermitant problem. ive tried voltage check across fuse top all 0. tried a clamp on amp meter on negtive side batt cables and get .6 to .7 amp draw but the amp meter removed still read .2 to .3 to 0 drifting. talk to dealer he said don't know. my thinking is a module not going to sleep? pulled some fuse no change. charged to batt which now reads 13.14 volt but odd thing is . . im using a 3 amp battery tender which has a amber light indicating "charging" and a green light indicating full charge. over night it charged but at 13.14 volt the amber light indicates its still charging. what im i missing . i told if i have a module not sleeping and if i disconnect the battery it will reset any defective module and nothing to test for. next i might try a hall effect coil on the battery cable to have a 24/7 amp/millamp reading but i dont know if a hall effect coil is accuret. any ideas?
