When using the sonar unit say lost transducers signal you can wiggle the plug and the sonar starts working for2 or 3 minutes then repeat lost transducers signal.checked pins none bent but not a tight fit anyone else had this problem
when i first set up my 93 i had the same thing happen. I had tried to push in the plugs through the bracket after it was mounted, sorta like i was used to doing with a lowrance head unit. Then i figured out i needed to push the plugs through the bracket, then attach the bracket to the mount. When you put the unit in the mount all the plugs go in at once - haven't had any problems since.
