2005 RAM 2500 4x4 I had a dead battery, so I hooked up the charger to it. I forgot the key was still on. The charger was set to 300 Amp start function. The dash went nuts, the headlight flashed several times, I immediately turned off the charger, but there was a loud pop! under the dash. Now the truck will not shift gears and the low beams dont work. PLEASE HELP!!
The pop sounds probably indicates you probably blew a fuse or damage some wiring with the arc. Time to start pulling things apart and doing some electrical diagnosis.
