ok what a week of trying to find electric issues and i need help please .Frist i could not get out of park gear I WD-4o the slider that the key pushes to release the shifter to come out of park ok .Well that lasted 2 days This started the day after i pulled my 1941 Dodge Power wagon Home .Frist time my Durango ever pulled anything it had power with the 5.7 Hemi AWD . Then a few days later i sprayed more WD-40 on the slider to get it out of park gear again .After that more issue started . My ABS & Brake & engine light came on & i had no turn signals ,No tail lights ,no Brake lights on the rear of durango ..So i started looking checking Relays & fuses They all are good .So i replaced the break light brake switch still nothing check the bulbs all good except the center one in the hatch it was burned real bad .So i replaced it still have no power to brakes lights .But now i have signals & tail lights on both sides but no brake lights and nothing to center light .Now this is where it gets real strange .I went to start it & now i have nothing any where no lights ,no engine turn over .So i checked the battery it was dead .so i tryed to charge it with 12 volt charger i could not get over 12 volts in the battery so i disconnected the - neg cable off the battery the battery charge to like 13.8 volts .But as soon as i put the - neg cable put on the battery it drop voltage like from 13.8 volts down to 6 volts within a 60 seconds .So i disconnected the - neg cable recharged the battery to 13.8 volts and left the -neg cable off . Then i checked my fuses under the hood & i freaked out every fuse has between 0.92 volts to 0.98 volts & the fuses at kick panel has the same . So i disconnected the 7 trailer plug & check the Fuses again this time the volts went down to like 0.53 volts . So then i pulled the 50 amp fuse out of the power Dist center cause it has power on both side of the prongs when the 50 amp is pulled no sure why or how it can have power on both prongs without a fuse .Then i checked the fuses again now they read about 023 volts with the 50 amp fuse pulled & the - neg cable off the battery . So still no brake power to brake light .& a battery drains like crazy when the - neg cable hooked up .I need some good help ,Ideas . and alot of good surport on this BIG ISSUE PLEASE HELP .& Thank you very much .
