ELECTRICAL PROBLEM GPS POWERS DOWN

[GregeMoose]

Has anyone experenced this. I recently installed a new Lowrance Global Map 3500c. When I start my motor my GPS unit powers down for a split second. I get the start up screens and lose the trail I was making.I have the unit and also the antenna powered out of the fuse box. My old unit (Global 2400) was powered from the exact same sorce and it never experenced this problem. Anyone got any ideas?

I assume your GPS is run from the same battery that starts the motor? If it is how old is your battery? Check your GPS manual, there is probably a low power shut off and if you battery drops below a certain power level while starting the boat the GPS unit will power off. Happened to me a lot with my depthfinder until I got a new starting battery.

Muskie Guy,

The battery is about 4 years old. My old GPS (global map 2400) did not have the same draw this unit (3500c)does so it just may be that the battery is going bad.

Thanks for the help.

I would agree on the bad battery.........

Gregemoose, I am having the same problem. I just installed the 3500 also and was wondering what you found out. My vexilar edge graph has a volts reading and it seems fine, but if I try to start the engine, my gps shuts down but not the edge or fl-8, and they are connected to the same bank. Maybe I have to connect the gps to a different source. Let me know if a new battery solves your problem, I don't think mine is bad yet. Thanks for your help.

I've yet to try a different battery. I'll update here when I have.

I've finally replaced the battery and that solved the GPS powering down problem. Thanks again for the help.
