ifinder H2O 12v won't work without batteries?

[GoodToGo]

Ran into a situation sledding/fishing last weekend. Went to come home, fired up the ifinder, and it was flashing "low batt" in the upper right hand corner. I had the external power supply hooked up, so I switched the page to show power level and it showed "external power". It then powered down. Repeated attempts to fire it up just resulted in immediate power downs. It was as if it needed good batteries installed for the 12v power supply to work. I didn't have any, luckily my buddy's GPS worked and I followed him home (after dark). I checked the power supply when I got home and it was at 3.7 volts. Users manual and on line checks haven't shed any light on this. Has anyone else run into this?

Power cord is probably toast. Theyre famous for that.

Mine wil run on 12v power for about an hour, until the part that plugs into the 12v receptacle gets so hot it trips something and it goes to battery power. you will know, because the screen backlight will shut down to conserve battery power.

Be careful running that. My H20 zapped my Navionics chip because of that darn power chord.

I did confirm that the power cord was producing the appropriate voltage.

Mine just started to do the same thing. Anybody know how much and where a guy can find one?

lowrance doesnt make that unit anymore it was discontinued and the 12v power cord is very very hard to find..so u might want to get some rechargeable batteries if the unit still works

You can get the power cable through LEI Extras. I just looked them up to be sure they carry them, and they were right there.

I would not bother to purchase another power cord for this unit.

I have went through 4 straight cords and I now run mine on rechargable batteries.

The cord are JUNK and they will not refund your money for a bad cord.
