[spf645]

Has anyone had an issue with amp gauge needle bouncing? Then would settle for a few seconds, then back to bouncing. I did change out the battery. Same issue. Then new Alt, and regulator. Same issue still. And also noticed headlights would bright and dim as amp needle bounced. When engine fans came on it pegged the needle to the - side of gauge. This is a spf car, 645. Any ideas Blas, or anyone. Thanks .. Car did not have this issue until the last time I drove it,,, before new battery.
