Hi, new to this site and need help with a major electrical issue. I have a 1992 suburban 2500. I have put a new alternator in it and it still won't charge the battery. the battery is new and the alt. has been rechecked. All good. When I applie the brakes the wipers turn on or when I turn the radio on the wipers also turn on. When it rains the anti-lock brakes also go whacky. The truck has 250k miles on it and would like to see 500k. Has anybody everheard of these problems or at least know where to start to find them. Thanks for any Help at all.
