Fleetwood Discovery 40X

We are just getting our Diesel Pusher out of storage and it won't start. I have two questions:
1). Is it a 12 volt or 24 volt? What is the difference?
2). What is the best way to boost our motorhome?

Thanx
  • Thank you. We put a charger on the battery and left it over night started:). We had taken the house batteries out for winter and no shore power. We are now ready for summer. Yeah
  • Hi gemert, thanks for the correction. I described it then put the wrong term to it. I do know my series and parallel connections. Doug

    It is a 12 volt system with more than one battery connected in series. That is positive cable to positive terminals and negatives to negative terminals assuming all are 12 volt batteries. Connected in series is still 12 volts but twice the amperage. Make sure all batteries are fully charged, at least 12.25 volts to a full charge at 12.75 volts.


    Careful!!! This post has right and wrong in it. If you connect 12 batteries in series the voltage will add and fry your electronics. 12+12=24. What he described is hooking them in parallel with Pos to Pos and neg to neg. In that case the voltage will not add but remain the same as he described. So I believe that was a typo but if you were to find a diagram of batteries in series and followed it, you would be in trouble.
