FOUR WINDS INTERNATIONAL
The primary point to keep in mind about the unit’s 12-volt system is that the automotive chassis
alternator supplies power to both the automotive systems as well as any auxiliary battery and
directly to the RV living quarters while the vehicle’s motor is running. Thus, of primary concern to
you is the condition of the vehicle’s electrical system and especially the alternator.
The alternator compensates for electrical usage in the vehicle, the power drawn by the appliances,
lights, fans and other 12-volt powered items as well as the charging of the automotive and
auxiliary batteries.
If the alternator isn’t keeping pace with the draw on the unit’s electrical system, while driving down
the road, it means you’re working in a negative mode: more power is being used than the unit is
putting out.
This means that you are taking power out of the batteries. If you draw too much power from the
batteries there may not be enough power left in the battery to start the RV or run any of the
appliances when you stop for a break or for the night.
So, always keep an eagle eye on the alternator’s output. Also check the monitor panel frequently
to see that the auxiliary battery is up to full charge.
The alternator will charge at a higher rate right after the vehicle’s been started, replacing the power
used to start the vehicle, but the charging should quickly go back to “normal” and hold its own even
when you turn on lights or appliances.
When stopped at a campsite that allows you use of the shoreline, the 120-volt electrical system will
recharge your auxiliary battery
When checking auxiliary battery condition, turn on several interior lights to place a load on the
battery. Under heavy usage in warm weather, check the fluid level of those batteries that require
attention to fluids quite often. Low battery fluid level is very harmful to the battery’s longevity.
If the alternator shows a discharge while the motor is running, turn off appliances and lights to see
if a charge comes on or if the alternator indicates “neutral”. Then apply a drain on the system to
see if a discharge returns. If a discharge persists, contact your dealer.
