So, I just bought a 1994 Chevy Silverado K1500 4X4. Has a 350 engine. Done a tune up, at which the windshield wiper motor was unhooked. I hooked it up, started it, now everything I do it dies. Just cannot find the problem, but know it is electrical somehow. The radio flashes on and off, the gauges constantly jump, step on the brake pedal, it dies, turn on headlights it dies, put it in gear it dies. Just hope the Chevy community could give me some insight. Thanks for reading and hope to hear some good ideas.
