while fishing yesterday when i hit my trolling motor switch it would reboot my lcx18c at the console,went back and looked and it was showing 4.9-5.7 voltage.thinking it was the unit i took the 18c off the bow and hooked it up at the console and it was reading 4.9-5.7 voltage,both hooked up on the bow it was showing 10.9-11 volts,so not the unit.brand new fully charged blue top,so i switched to a fully charged 31 series brand new wally world battery i carry if needed.has anyone had this problem or know what it could be,i checked the wiring and all looks good,no breaks or rubs anywhere,any help would be appreciated
Thanks

If you have the trolling motor and Lowrance unit on the same power source then you need to run a separate wire for the Lowrance.

the unit is hooked up separate on the fuse panel.been hooked up this way from the start,it just started this this sat.been working great up till now
