Thread: Low voltage hummingebird 998

Set one of the Readouts to Voltage and see if the voltage is dipping when this alarm pops up ...

You can raise the voltage alarm threshold higher under the Alarms tab ... But I would 1st troubleshoot to make sure there isn't a problem that needs attention ...

Is this happening while fishing or when starting the outboard? Live well on a timer running when it happens?

See what the voltage actually is as Rickie suggested. There are fixes if there is a problem.

Played with in garage .I fished Sunday ,,,My hummer is hooked up to starting battery .I did not hook battery charger up on return from lake .Voltage readout was 11.1 .Voltage alram set on 11.Cat fan alarm comes on mostly I think when bumping over to next tree or pallet bed .11.1 seems low to me, should be 12.5 I think ..Took starting batt to parts store to check they told me batt was good?? Hope to fish this weekend an play with some more if cold front dont shut me down Thx for help guys..!

11.1 at the unit is fairly low. Often the factory wiring for accessories isn't good enough to keep good voltage at the units, and you end up needing to run a dedicated pair of wires to the battery for your electronics.

11.1 is very low. First check the battery with a voltmeter. If its the same as your bird is saying then your wiring isnt an issue.

Are you running with the big motor or idling? Some motors wont charge the battery unless its over 2000 rpm which should be past idle speed.

Watch your voltage when running the big motor, should be climbing pretty fast. If not you may have a weak output voltage or a bad connection on the power cable from your motor.

Toss that battery on a charger. Should go to 12.8+.

Catfan Kevin22,rnvinc Thank you for help , Took boat out ,voltage meter on boat dashboard reading bout 11.1... matched hummingbird reading .boat cranking just fine I now,got charger on boat starter battery ,,, If idling battery amps go up some on dashboars meter ,,but thinkin more battery going bad ,,altenateor on boat engine ?? sorry bout spelling I was probally skipping school going fishing .Snipey

Charge it 100% then let it sit for 24 hours. It should read 12.5-12.8v. If its lower than that then you have a weak battery.

11.1 is just hovering above dead, 10.7 is dead on most.
