    I have. A 2013 with maxforce13 in it , yesterday the volte meter went all the way up my transmission started to act up saying F I disconnected one of the batteries it read it fine for 5 minutes and started to do the same thing finally I connected it to 2 batteries only and it was running fine , thought I had 2 bad batteries replaced the other two connected all of them same problem started to happen again and finally it’s just running on two batteries and it’s just fine , so I’m confused of what’s going on !!!
    Hope someone can put some sense in to me

    If you mean it is over charging, look for small red wire at the alternator and disconnect it and see if this cures your problem. This is your remote sense voltage wire and if it goes bad somewhere the alternator cannot read the voltage properly from the batteries and will raise the voltage as high as it can go.
