Since i am a newbie to this forum, i'd like to says hello to all user.

So anyways, i just bought a 1988 Ford 4-b(R)anger and having electrical problems. The problems seemed to discharge batteries overnight. Thinking that it maybe just an old battery, went to get a new battery installed. Drove the car, went home, tried starting the the next day and the battery is dead. So we decided to disconnect the battery at the end of the day. Next day worked with my dad on the problem and found this very interesting issue. Whenever the + battery terminal is disconnected, the wiper seems to have a life of it's own and run uncontrollable (non-responding to wiper controls) until you connected back the + terminal to the battery.

Had anyone seen and experianced this problem?

Any comments/suggestion/help is appreciated!
