A few problems...

Well I had picked up a set of 33s with 50% tread for $50 and threw them on the went on a few trails to see how they worked, it was pretty bumpy. Now when ever i turn, hit a bump and my truck jerk everything power flickers for a second. I tightened the terminals and checked the wires, didnt see any bad spots. What could it be? I have a 1990 Chevy K1500 RCLB w/ 5.7 if that helps.

Check to make sure the grounds are tight (manifold, frame, body) and that the connections at the alternator are tight.

Thanks, I'll check tomorrow as my parents like to block the garage door, so no light.
