I M having a problem with my 998. It will loose power on its own.. I am using 6.43 I believe for the software( factory installed). Any ideas on what could cause it to do this? Thanks

Check connection on back of head unit. Unplug it and reinstall making sure it goes in all the way. If in doubt remove power wire from gang plug and insert it by itself. If not there then go to battery connection and check that for being loose. Also check at fuse end wire connections. Also if you have the long glass fuse check ends on fuse and wires for wire ends that touch fuse for corrosion. I always install a fuse holder for blade type fuse with waterproof cover and solder wires. Hopefully you have it wired straight to battery.
That's some great advice, I had trouble with mine then went to a stand alone battery just for my 998 always make sure your battery is charged to its fullest.
Is there a good way to clean the prongs off I'm the connectors. That may be a problem of mine
I have to check again but I believe my power is ran from the battery straight to the unit.... At first the unit would shut off when i would be running wide open but towards the end of the trip it would just shut off randomly when I was ideling around looking or brush on the side image. .... Does this still sound like a connection issue. I had it in system status and was monitoring the voltage while ideling under a bridge but as soon as I opened it up the ride got rough and it kicked out. The unit is hooked to a separate battery from the big motor....
when does it do it., My 898 shuts off by its self in rough water and then wont boot back up for quite awhile .
Ehh the water was rough today when it kicking out but when I was ideling it wasn't as bad and it did that to
You might think about having the battery load tested...

Silly question but do you mean taking the battery in to see if it has a bad cell/cells's
Yes...the battery could show 12v with a meter but still could have a bad or dead cell ....Quote:

Mine did the same an it was a broken ground wire in the power cord. In the garage I turned the unit on and started at the connection on the unit bending the power cord till the unit shut off. The break was inches from the fuse panel.
As a former troubleshooter for many a DC circuit runs. GENERALLY speaking if you have intermittent power and motion is involved it shouts bad or weak connection. Corrosion of any kind at terminal ends can also cause power problems.
Troubleshooting anything is rapidly becoming a lost art in our throw away society. Over the years I have saved many a unit from the trashpile with simple fixes. My cousin was going to throw away one that had caused him numerous headaches.. The " trouble " with that fish finder was a corroded fuse.
Batteries that are just starting to go bad can cause odd problems also. Lead acid batteries have an expected usable life cycle of 5 years. That is the expected by abusing your batteries , overcharging or overheated or subjecting to freezing weather, over long periods of time can shorten this. Taking extremely good care of your batts can lengthen its life cycle. No guarantee but it certainly won't hurt.
Learn how to load test your batteries and maintain them will limit your problems out on the water. If you take good care of your connections and your batts you will enjoy your modern electronics more.
One more piece of advice. Get a good multimeter and learn how to use it. Don't have to break the bank here. They do have extremely expensive ones. But one in about the 39-69 range ought to be just fine.
And once you have a meter learn how to do a voltage drop test. There is no better way for locating bad connections or wiring.
You said it gets power from a separate battery. How does that battery get charged?
Power cable has a inline fuse on it and is hooked to the trolling motor battery... I know it has nothing to do with the trolling motor because that wasn't running when it would shut off. I checked the connections today and they were kind of loose but I'm not ruling that as the cause just yet... I have a on board charger. One bank goes to the trolling motor battery and the the other goes to the starter battery. I also checked the inline fuse and all was ok with that
You might check to make sure the battery is not moving. If running on rough waters is causing it to shut down, then there may be something hitting the post causing you to kick the power off.
Do a battery test. Borrow a good battery, one of your cars or friends, or you could buy another battery. After the test if it still does it then take the new one back. Hook the depth finder to the borrowed battery and run down the lake a few times. If it clears up then you need a new battery. If it doesn't, then there is a short in the wiring somewhere. Good luck.
