Used a volt meter on the power cable where it connects to the unit. It briefly registered 4 then 5 and then a small spark on the ground from the cable. Now no power registers at all. Does the power cable tie in with other cables or does it run by itself to the battery? Is there a fuse involved?Brad

Alright, here we go. I removed the both panels (acc. and trolling motor) and the cup holder. Found the wires from the unit to the acc panel. Acc switch itself is drawing over 13 amps. Traced the positive wire from the switch to the fuse and separated, fuse looks good. Traced the negative to the first splice and tested again with the voltmeter. Still drawing over 13 amps. Continuity (sp) on the wires from the Lowrance plug to the the the first splice (negative) and the fuse insert (positive). Is it common to patch in the NMEA 2000 Power cables with the regular power supply? The negatives are twisted together and spliced to heavy gauge wire running to the Acc switch and the positive is spliced to heavy gauge wire w/fuse and also joins the regular power supply (w/fuse) and attaches to the Acc switch. Brought the unit back to work to double check and it works fine on the power cord from a 522. At this point I dont know what the problem could be. I am going to pull the power cord and check for rub spot that could cause a short and replace the two fuses. The connections to the Acc switch look good and the splice connections look good. I guess the problem may be in the plug that connects to the unit? Brad

Mike,Upon reinstalling are you running a small bead of silicone on the back of the unit or sealing after the hardware is tight?Thanks for your help,Brad

I have not checked the voltage when using the trim button, regular check at the power cord going into the unit was fine. The power cables are wired into the acc switch. I guess I should also check my battery terminal connections (duh). Brad

Any idea what the second set of wires w/in-line fuse holder is for? Could that have an effect on the Lowrance unit? Brad

I am by no means a genius, but I know better than to hook it up to the trolling motor batteries. Could be the battery, what is the recommended starting battery size (225 Pro XS) so I can get one while Im still at work? Nothing else is turned on, just the Lowrance….

Is this going to be near the tongue?

Checked the ground, connected to the botom of the brake actuator(?) and intact. Plugged up to the truck and everything worked. Go figure. Cold weather/water have any effect? Dont know, just glad to see the light……. Thanks for the responses, Brad

Where can you get one of these “squeezers”? Can you rent it? 3/16″ on the size of the drill bit? Thanks…
