Just bought 2 cannon electric downriggers. The guy I bought it from said he couldn’t get the mag 10a to work. I brought it home Hooke it up and tapped the motor with a hammer to see if it was just seized from sitting. Now when it is hooked up it automatically starts going down and will not stop if I try and move the switch positions. Any ideas? I ordered a new switch hoping that the switch is just stuck in the down position. Could it be an electrical issue elsewhere?
