RE: [A/S] Current rating on 12 volt outlets

Jim,
All A/Ss are negative grounded as are all RVs.  This practice came from
the fact that cars/trucks are also negative grounded.  If someone had
crossed up the wiring at the trailer battery(s), the result would be
blow fuses in the charge line circuit (ie you would NOT be able to
charge the trailer batteries from the tow vehicle).  Also the
electronics in your A/S, such as the radio would not work as they depend
on proper polarity as well.
