Crazy Zero Off Touch Screen

OldGuysRuleOldGuysRule Posts: 45 Baller
I took my 2015 Mastercraft Prostar out on open water today to pull friends free skiing and air chairing. After a while the ZO screen started going off and on at will. The timer window also started popping up on the screen. The screen was very warm to the touch and trying to switch speeds or switch to trick mode also didn't work. I finally outsmarted the unit by increasing the slalom speed up to 36 so I could continue pulling kids at speeds lower than 36 so it wouldn't engage. The On/Off button kept going off and on. Later in evening I went back down to dock and started the boat and it seemed to be OK. Boat has 160 hours on it. Any ideas out there....HELP!?

    Should be under warranty. I was talking to a E-control engineer he was saying those screens are on the low end for quality. You could try disconnecting power from the battery and see if resets.

    yep, had similar issues with our original screen on our 2015 ProStar. Had it replaced under warranty.

    Had the exact problem on my 14 Prostar. Turns out I had a bad connection on the battery ground terminal and the battery in my boat didn't have the required cold cranking amps. Installed correct battery size with good clean connections which solved the problem plus my big 6.2 seems to start much easier now! The dealer said bad ground connection is the main issue they see in relation to the screen problem. The screen can go bad as well but that wasn't the case for our boat.
    Ski it if you can!!!!

    Incorrect cold,cranking amps? Did it have 13 or so volts? Voltage is all the screen would know.
