In normal conditions a converter will not overcharge a battery unless (a) the battery has low
or dead cell(s), or (b) the converter has a malfunction. The charging module on some
converters have a positive shut-off and on others there is a reduced charge rate to a very low
amperage.
A fully charged battery will read 12.7-volts DC and 1.265 specific gravity at 80°F (32°C).
A battery is considered discharged at 11.8-volts DC. If the voltage drops below these
levels, permanent damage will occur.
The RV battery is installed in parallel circuitry with the battery on your tow vehicle. Both
batteries supply power to your RV, so it is important not to discharge the tow vehicle
battery below the level of power required to start the engine. To prevent this occurrence
while parked, disconnect the wiring harness between the RV and tow vehicle or install a
battery isolator (see below). When the tow vehicle’s engine is operating with the RV
connected, the vehicle’s charging system will charge both the vehicle battery and the
auxiliary battery.
BATTERY ISOLATOR (FOR TOW VEHICLE)
A battery isolator should be installed for two purposes. First it receives current from the
alternator and controls distribution of energy to both batteries. Secondly, it serves as a
check valve to prevent energy from being drawn from tow vehicle chassis battery. Energy
in the tow vehicle is now preserved to start your engine.
Two types of isolators are available, mechanical and solid state. Each type has an amperage
rating (70-amp per side) to indicate it’s capacity of operation. The solid state type of
isolator, although typically more expensive, will provide the best overall performance.
Your independent, authorized dealer can assist you with purchase and installation if you
choose to purchase a battery isolator.
LIGHTS
Exterior
All exterior lights, such as tail lights, clearance lights, turn signals, brake lights, etc., are
energized by the tow vehicle power. When attaching wires to your tow vehicle, carefully
and tightly tape all connections for moisture protection.
Refer to diagram (Fig. 25) for the color code of the seven pin connector. The connector
between the tow vehicle and your travel trailer may build up corrosion with extended use,
and should be cleaned periodically to insure good electrical contact.
Porch
Porch light(s) on either sidewall will have switches located on the wall inside of the
entrance door.
