522 keeps shutting down

8 posts in this topic

I have a low 522. Problem is everytime I start the motor it shuts off. So far I have ran new wire (temp), Batt. direct to unit. Thought it was bad ground but still does it.

Turn the backlight off when you start and all should be ok. Same thing happened to a friend of mine

When I posted this same problem most people responded that my starting battery was weak. I did observe that if I turned down the screen lighting before starting the motor that it would stay on and not have to restart. Maybe this will work for you too.

When the engine is started it creates a large draw on the battery which pulls the voltage down below the minimum requirements to keep the graph on. A fully charged battery won't drop below this threshold, but one that is weak may allow that to happen during start-up. A new battery would help or connecting the graph to a different battery would work too, but personally I prefer that the trolling motor batteries are used for the trolling motor only.

I would check the battery to make sure it's full of water and the connections are good. Then I'd put it on a charger to make sure it's fully charged. Boat engines will maintain a battery voltage but won't bring a battery to full charge while out on the water. Putting a charge on battery when you get home is especially important for deep cycles because the boat engine won't do the job regardless if you run around the lake WOT for miles and miles.

I agree, it's most likely due to voltage drop in your starting battery from turning over your outboard motor. I'd make sure your battery is fully charged, then get it load tested for a gauge of how strong the battery is.

LMITOUT is right, it's very important to maintain your starting battery with a charger to keep it at full charge all the time.

My 522c did the same thing as you described on Tuesday evening. It was the first time it has even done that. I guessed it was due to the starting battery being low on juice. I had the livewell and depthfinder on for about 3 hours without starting the motor. Then it was time to go and the motor started and the graph shut down. I am sure I can charge the battery back up and it will be fine.

Time for a new battery is likely very near, most graphs shut down if spiked below 10 V. The amp draw from the starter is bouncing it below 10 V and shutting the unit down.

You may also want to monitor the voltage by turning on the battery alarm on the unit and set it at 11.1 volts, this will give you warning if it is weak.

Well a lot of top ideas which sorta worked. After going through the wireing, connections and chargeing the batt. Ed carlson gets the grand prize.Brought the battery in this am and found out it was shot. Less than a year old they were happy to replace it. Now it all comes together. Thanks eveyone for your ideas.

    • Glad to hear you're back up and running again.          
    • I got my boat back today and it runs great now but the mechanic said I had too many idling hours on it and it had a lot of carbon build up. I have trolled a lot with this motor . It has ran great but I did have  this recent issue with it where I had to bring it in and it runs good now. Mechanic recommended run it more often at higher rpm's.  For those that troll with their main engine,  how often do you run in a higher rpm's? I  use carbon guard  and thought that that would prevent the carbon buildup.  If I trolled for three or four hours at a higher RPM would that be too much ?          
    • Saw some reports from Algoma that looks like fishing has picked up some out there and some bigger fish being caught. I'm not ready for snow yet but I hope we actually get some this year. 
    • Well I got it done. I got some bolts washers and rubber grommets. I drilled holes in the counter top. then brought the bolt up through it put a 1/2in rubber spacer then a washer and bolted right into the bolt holes where the leg levels went. It looks nice and will be nice not having to put the fridge up and down every time a guy moves the ice castle and should hold fine driving down the road.         Nice exactly what I need to finish the project, so the fridge door doesn't fly open when driving down the road.

    •   And it has some sort of virus.
    • The boat is getting lots of use,,,, Heading to Algoma july 29th and back to Isle Royale later in august 
    • You're bolting a mini fridge to a countertop but worried that a tie down strap will make it look trashy? OK then.
    • The strong rainfall of the last few weeks was compounded this week with more rain accompanied by high winds, thunder and lightning, as well as several tornado watches across the state. Downed trees and branches and flooding was reported at numerous state properties throughout south western and south central Wisconsin. State park crews were actively clearing roads and trails, and we're expected to have additional updates before the weekend. Anyone planning on visiting a property in these areas is urged to contact the property directly for the latest conditions.Water levels across the state are still elevated and this week's rains means sand bars will likely be in short supply again on the lower Wisconsin River. With the high fast moving water many kayakers and tubers are taking advantage of the situation. A group of kayakers on the Peshtigo River said with the fast water they shaved an hour off the time it normally would take them for a river trip.Wild weather has put a damper on fishing pressure across the state and there are isolated reports of partially submerged fishing piers. Anglers have reported some success for catfish on the St. Croix River and anglers have been having success fishing the Flambeau River for musky, walleye, northern pike and bass. Largemouth bass fishing has picked up with high waters in Dane County rivers and there were reports of an uptick in walleye and perch are coming in from Lake Winnebago. .
