Lowrance HDS 7 question

[snoozebutton]

Would a bad battery cause this unit to turn on by itself? I got to the landing Friday and the battery was dead, as soon as I hooked up jumper cables, I noticed the locator started booting up. I tried shutting it off and would get the screen saying "Powering Off" and as soon as the screen went black it would start booting up again. Took the battery out of the boat and had it tested and it tested bad. Now that there's a new battery in the boat, my locator no longer turns on by itself. I'm thinking the bad battery was causing the problem, is that possible?

Yes, if the voltage drops too low your HDS will not work correctly .... the symptoms you described about booting up and powering off, and screens flashing, are common with low voltage.

This happened to my brother-in-law over the 4th. New HDS 7, first time he fired it up after installing. Screen flashed twice, then nothing. We thought either a wiring error or he got a bad unit out of the box until we checked the voltage at the connector. It was only 11.5 volts but the thing wouldn't fire up until after he charged the battery. Then everything worked properly.

Still working properly since putting in the new battery so I guess I can say case closed. Thanks guys!!!
