I’m on the lake now and my graphs are shutting down when the motor is running. They reboot when I shut it down. Both are wired to the cranking battery which was showing fully charged this morning. Got a clue?

Do they shut down when the motor gets started? Will the start back up after the motor gets started or do you have to wait until it gets turned off?
They won’t come on as long as the motor is running.
I've never seen that happen. If you can move the power for the graphs over to the TM batteries. When you get home check the cranking battery before you start the motor and then when it is running.
Will do. Thanks
Saw that happen once when the motor was over charging,,,

This would be my bet....Champ is right on with checking the starting battery.....over voltage will shut 'em down also.....Originally Posted by omcforever
Under voltage will shut them down. Somewhere around 10.5 volts needed to run most units, with only 12.5 volts charging at the battery, you may have enough voltage drop in the system to shut them down. A weak battery won't help.

I haven’t had a chance to check to check the cranking battery since I got back from the lake but I did a week or so ago. If I remember correctly, I had 12.2v or so engine off. 14.4v or so engine running.
Wing nuts?
No. Teflon lock nuts.
I checked my cranking battery today. 12.8v not running. 13.2v running.
Do the graphs run with the key in on position, motor not running? How are the graphs wired, both positive and negative?
They run with key on. Shut down when the motor is running. I took it for a test run a couple of weeks ago and didn’t have that problem. All I did after that was to replace one of my trolling motor batteries. Didn’t touch the graph wiring.
Will they turn back on after engine is started? Never mind.....already answered....got me dumb founded....
Me too. I think I'll wire the graphs to one of my TM batteries as ChampioNman suggested before I take it out again to see they shut down. If they don't I think that'll tell me there's something going on with my cranking battery. Is there a down side to wiring graphs to a trolling motor battery permanently? Last cranking voltage check was 12.8v not running. 13.2v running. I'm assuming that's about normal?
Do you have a on board battery charger for all 3 batteries?
The only drawback to wiring to the troller batteries is the amp draw from the troller motor can cause interferrence, but for a test it should be done.
Ok and yes, I do have an on board 3 bank charger.
I will be in Aiken and Augusta over Thanksgiving. Maybe we can get together and work out some bugs,,,and fish "The Hill".
