Wiring Lowrance 522c

10 posts in this topic

Last year I got a new Lowrance 522c to replace my old Bottomline. After I installed it, it would turn off when I started my big engine. This was a pain while I waited for the GPS to reacquire.

I replaced the starting battery (as well as the trolling batteries) thinking that there would be less voltage drop causing it to turn off. Same problem, it would still turn off.

This spring while the boat was sitting conveniently in the garage, I installed new 12 guage wire (with inline fuse)and separate control switch and connected it to the starting battery. When I cranked the engine, it turned off again.

Finally, I connected my new wiring to one of my trolling batteries and it worked. No interference from the trolling motor and it doesn't trun off when I crank the engine!

I'm not a mechanic, but I'd say there is something going on with your starter. It might be drawing too many amps dropping the amount the electronics need to stay on. Maybe have your starter checked before it leaves you stuck on the lake.

I tend to agree. You said you have a new starting battery, as long as it has enough cranking amps for your motor then there is likely to be something else going on with the starter that is causing the voltage drain.

Running electronics off your trolling motor batteries is not a good idea either. You will get interference at some point. You also run your battery down faster, if you're running a 24v system it draws one down more than the other. Best to get your motor checked and put it back on your cranking battery.

I believe this same topic has come up before but I did not keep track of the solution if there ever was one. Maybe someone remembers the thread and can bring it back. I have a friend with a similar problem and would be very interested in the fix to share with him.

Had the same problem. The only thing to solve the problem is take it back and get a humminbird. Thats what I had to do.

What kind of motor? My 115 merc doesn't cause this with my 522. Try putting a voltmeter across the power when cranking. Something weird going on. The voltage shouldn't drop that low.

I had the same problem with a 30hp Yamaha. I kept my old battery when I got the different rig. It would happen when the battery became low. The battery finally went kaput and I replaced it with a battery with more cranking power. It solved my problem.

I have that problem from time to time. Usually when I forget to charge my batteries after an outing. A new battery took care of it for me. If that doesn't work for you, like others said, I would check the starter.

    •  I use a Digger mount on my ATV and sled.  Its fast and easy.   I'm on the ice everyday testing and tweaking Nils blades. I rack the auger on every blade change and some days that could be 20 times so for the me the Digger is exactly what I need.  The clamp on the Digger makes fast work of securing the auger and removal.   The height of the Digger frees room on the rack for more gear.      Once in a while we'll take my buddies ATV out fishing.  Hes got no auger rack so we'll bungie the auger to the ATV rack. It works but it makes me appreciate the Digger rack all the more.   Any rack would be an improvement there.   In the past guys have posted their homemade racks and I hope they do so again.   
    • Currently have a couple empires. Most likely toss one of them in. If I go with a furnace I'll use a small plug in step down transformer 120v AC to 12DC. They are cheap as hell basically an oversized cellphone charger.
    •   You realize the only ones taking Calexit with any seriousness are conservatives. Which means conservatives are the ones falling for the Russian propaganda. Liberals say it sarcastically because conservatives think the country would be better off without the "coastal liberal elites" (even though California pays in $405 billion in federal taxes and receives only $344 billion in federal spending, meaning the rest of the country would be $61 billion poorer without California).
    •   As in the one that lets me use his cabin for Turkey and Deer hunting!
    • So Bear, please describe what your policy on those drugs now banned would be, in as much detail as you can.     I am really wondering what the alternative envisioned by the "stop the war on drugs" folks is.      
    •   Bear, I explained why we are stuck with the two party system.   If you don't like the two we have, you need to "pull a trump" and take over one of them.     Good Luck. 
    • Actually only one species of bumblebee so far.     I have no idea how one distinguishes the species of bumblebees.   
    • If this is your carb # 6 is the drain screw   http://www.marineengine.com/parts/yamaha-outboard-parts/1997/30/30ELHV/620301630004
    • I would suggest using non-oxy gas also!
    • I highly doubt it needs carb kits if only sat that long. Draining the carb bowls and spraying carb cleaner in there can clean things up a lot and loosen sticky floats. Should be a main jet on each carb you can pull to drain carb bowls and spray into and clean jet. Put in fresh gas with seafoam in it and new plugs and it will probably run. Impeller is a pretty easy job to. Should be able to find a video on u tube on how to do it. I would drain my carb bowls on my old 115 2 stroke every spring and you would be surprised at the slimy stuff that came out of them sometimes and that was just sitting over winter.
