in your electrical system to protect wiring and components when
overloads appear or short circuits occur. Radios, stereos and possibly
other components may have “in-line” fuses attached to their own wire
harness. Two 40 or four 20 amp fuses are in the converter, protecting the
converter should you connect a battery up backwards. Fuses will blow
rather than converter.
Circuit Breakers
are placed at several locations. An automatic reset
breaker is placed within 18 inches of the auxiliary battery. This breaker
will automatically re
set upon “cool down”, normally within 60 seconds.
A 30 amp breaker is used for the automatic reset breaker which is
installed in the load center to operate your slideout. All wiring used in your
coach meets correct amp rating correlated with fuses and breakers in
respective panels as required by code. The RV battery is placed in
parallel circuitry with the battery on your tow vehicle.
Care needs to be exercised not to drain both batteries
together. There are two methods of avoiding this
condition.
First, disconnect the tow vehicle when parked and/or
using your coach.
Second, a battery isolator may be installed in your tow vehicle to prevent
power drain from batteries in both vehicles. This device “isolator” has two
useful purposes. First, it sends current from the alternator to both
batteries simultaneously. Secondly, the isolator prevents draw from the
tow vehicle battery preserving power to start the engine.
Contact your dealer should you desire an isolator for your protection. Two
types are available, mechanical type, or solid state which is the best and
most expensive.
Power Cut-Off Switch for Battery
This switch is normally located outside on the A-Frame with a red knob.
Vertical position is OFF. Turning knob 90 degrees to right will be the ON
position. Remember, if switch is turned off, battery cannot be charged.
Along with the switch, there are 2 or 3 12-volt breakers under the black
cover beside the cut-off switch. Size of these breakers are 6, 10, 20, 30,
and 50 amp energizing various items in coaches.
DO NOT replace circuit breakers or fuses with a higher current
rating than those supplied with your coach. Over-fusing can
cause a fire hazard by overheating the electrical wiring.
