My turret was not turning properly, skipping teeth. I've fixed this issue on another before, not a big deal. Tested it while body was apart, worked great but while lifting the top half I pulled a couple of leads from the boards on the bottom half. Went to put them in and when I tested again, the sound board just made a repetitive pop sound and the turret would not turn. I had accidently switched two leads. Swapped them back and sound was normal and tank ran again but turret would not turn. Tested the motor to the turret and it's good. I feel I toasted something on the board that controls the turret. Anyone know if there is a place to get new boards or someone who could trouble shoot mine if I sent it in? Hate to think I screwed it up. Why they made those leads interchangeable I'll never know. Thanks.
