Hello my name is Bud and I live in San Antonio, Texas. I have a 1998 Ford Ranger XLT 3.0 6cyc. 4WD. I recently had to buy a new battery. When I connected the new battery I didn't realize the polarity was reversed. I quickly disconnected the battery and connected it the correct way. Truck started right up and I drove it home. A couple of days later I noticed the battery charging gauge showed battery almost dead and the battery warning light was on. I am afraid I seem to have damaged the electrical system. I would appreciate any help or advice I can get to correct my screw up. Thank-you.
