heres the deal 2002 durango--hubby put new alternator on, (no he didn't disconnect the battery cable first) touched a wire and sparks flew and now 4 wheel drive light is out and my -service 4 wheel drive-- light is on. Took it to a garage today and they can't find the problem yet. Thought it was just a fuse, checked something else to but nothing. Gotta bring it back in to see if its a modular. Any other ideas of what to check. After the garage had it the --service 4 wheel drive -- light is not on anymore. Would disconnecting the battery cable reset the computer ?? Not sure what to try.
