If nothing eletrical works it may be because something was on and drained the battery. Around 8-9 years ago I pushed the on button for my flasher and the button stuck in the on position. To fix my problem I unhooked the battery and cut the hot wire going to my flasher and installed a toggle switch. I routed new wire so the switch is just hanging out of the way barley under my dash; I then reconnected my battery wire. The switch is easy to reach but still not visiable.The on button has been stuck on for years but I can still turn my unit off.


The 332's had issues with turing themself on. A lot of people sent them in for repair under warranty but once the warranty expired all Lowrance would do is offer an upgrade at a reduced price. With the massive problem they had they sould have recalled the unit or fix any unit with the defective key pad regardless of age.
