Question about Lowrance M68C GPS Receiver
The unit is powered by a 12 v sealed battery. The unit will power up for a couple of seconds then shut off. While on the screen has a large area that is darkly cloudy. I rotate 2 batteries and they both are charged. The company said it won't repair the unit simply because it is older than 5 years old. I think the unit is 6 years old.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

had same problem. the cause was corrosion in the boat wiring. the power wire was corroded 95%thru. there was enough voltage to start the unit but when the sounder kicks in the voltage dropped below minimum and the unit shut off. took a LOOOONG time to find.

It sounds like you may have to send it out for service, but before you you do there are a few things you can try.
Low voltage can cause erratic behavior. Since you already wired directly to the battery, check the plug for corrosion.
Try unplugging the transducer cable to see if the display still behaves erratically. You wont see depth readings but you should still see the screen going black. If no erratic behavior with transducer unplugged then problem is in the transducer cable or the plug. A common source of failure is at the plug because the added stress of plugging and unplugging cables can cause the socket to twist slightly which can cause a short.
Make sure you have the latest software update.
How to see if your LCX-19C is already using version 1.8.0 software:
Copy it onto a blank MMC card and install it in your GPS. The GPS should prompt you on how to install the update.

Yes you have to hook up the red wires together to the + and both black ones to the negative, otherwise the antenna won't be supply in current , and don't forget to insert behind the red wire a fuse and a switch to avoid to discharge your battery .
