F350 with 4 batteries and the Link-Plus LCD display

[rasemuae]

I have a Wellcraft Scarab 35 with 3X250 Yamaha V Max on, and I decided to replace them with 2 X F 350;

I have 4 batteries in the boat, and neither me neither the "great" Yamaha dealer in the emirates is NOT able to make the right wire connection on the boat in order o have the Engine and the house connection battery displayed on the "new" Command Link® Plus LCD Display,,, "the smart display;

I don't know even how to connect the 4 batteries for the best since I used the boat 2 times and my house battery was down !

On the display I can see only the Voltage of the Engine batteries and not the house/sub batteries voltage, its shown as NOT seen/not connected;

Please, any one can help assist in this????

You have to go into the setup menu and select the house voltage icon to be displayed. Then, you have to have the isolator cable installed from the motor to the house battery.

F 350 with 4 batteries not shown on display

Thank you so much, I will try it and inform you, but, I believe that Yamaha people did try it first as per your kind sketch , did not work… I will check again and come back to you FYI;

Thanks a lot

First, only two battery voltages will be shown on the display. One is for the start battery. The other is for the house battery.

Actually, battery voltage is shown only when the motor is turned off but the key switch is on. Engine charger output voltage is shown when the motor is running.

The voltage for the start battery comes from the battery cable circuit. The voltage for the house battery comes from the battery isolator cable circuit that runs to the house battery.

I presume that of the four batteries, two are used to start its respective motor and that the other two are paralleled together to increase their capacity. Or perhaps, each motor has one start battery and one house battery, with the house batteries not being connected together. In other words, you have two separate house circuits. See attached as just one of many battery configurations that can be used.

I've done that, not working ,,,, and we changed also the display it self, not working still;

Exactly
it is exactly as per your picture;
Showing Both, the Engine and the sub, but, engine gauge is shown perfectly the voltage but the sub its 0.0 always, with and without engine running;

Yes sir, I did all exactly as per your configuration …. we also replaced the LCD … in case was not working…. same result;

[rasemuae]

I imagined that maybe the LCD require some USB to be programmend / activated in order to see the voltage of the Sub battery…. and the Yamaha dealer here in the Emirates are not aware of,,,, ;

Batteries are connected properly, I checked it , Yamaha did a cross check, another guy who is into boats also did…. Batteries are all charging proporly but the Display is still the same…

I wander what to do …

Engines are brand new 2013

I used the boat 2 times and my house battery was down !

On the display I can see only the Voltage of the Engine batteries and not the house/sub batteries voltage, its shown as NOT seen/not connected;

So did you make some changes to the wiring?
Seems like you are saying that house batteries are charging now and I am not sure if your original statement means the subs were reading 0 or if they were not showing up at all but are now.

I would think the info comes from the motor ECU's and sent to the CL+ ,
Did you use the Yamaha optional isolator lead cables or did you just run your own wires?

Hi

Yes they did all changes from scratch and now batteries are all charging fine but the display issue is the same only engine batteries gauges are working and the house (sub) are still the same as of day one as per the picture posted above.

Using an external tester / voltmeter its showing the charging process is fine . But not reflected / reported on the LCD
