DYNASTY 2006 ELECTRICAL SYSTEMS - CHASSIS — SECTION 9 • 283
CHASSIS ELECTRICAL - INTRODUCTION
A majority of the chassis electrical functions are designed to operate from 12 Volt DC (direct current) power.
This is why the chassis batteries play such an important role in the function of the motorhome. Therefore, it
is important to keep the 12 Volt DC system(s) in good working order. These systems, with their incorporated
electronics, are voltage sensitive. If DC voltage is not within specifi cation, some electronic items may be damaged.
The two different systems, engine and house, have separate battery banks. The engine batteries supply 12
Volt DC power to the front distribution panel located in an outside compartment by the roadside front wheel. This
panel contains mostly engine system fuses and wiring such as headlights, taillight, dashboard functions, gauges,
etc. The house batteries supply 12 Volt DC power to the distribution panel located in the bedroom. This panel
contains fuses for the house, interior lighting and appliances.
BATTERY DISCONNECT - CHASSIS
The main battery disconnect switch, located in the curbside battery
compartment, controls the DC power to the front electrical bay and to most
components in the rear run box. Most chassis and engine functions are interrupted
when the battery disconnect is turned off. Some electronic components of the
engine and transmission require a constant power source, and will continue to draw
power when the disconnect is engaged.
Turn the main battery disconnect switch off when the motorhome is going to be
stored or when performing electrical maintenance. If possible, leave the motorhome
plugged into an AC source with the battery disconnect switch on to help prevent the
possibility of dead batteries.
If an AC source is not available, and the motorhome is going to be stored more
than 48 hours, it is recommended to turn the battery disconnect switch off.
WARNING:
When welding is involved for motorhome repair or modification, only qualified, experienced
technicians should weld on the chassis. Improper welding procedures and materials
may weaken the assembly or result in damage that is not obvious and may not cause an
immediate problem or failure. Unauthorized modifications or repairs to the chassis could
result in a forfeiture of warranty coverage.
DANGER:
Due to the sensitive nature of the electronics on the chassis, the following precautions are
required to protect electrical components in the motorhome chassis:
1. Disconnect the (+) positive and (-) negative battery connection.
2. Cover electronic control components and wiring to protect from hot sparks.
3. Disconnect the terminal plugs from the engine Electronic Control Unit, located on the
passenger side of the engine block.
4. Disconnect all the plugs from the transmission Electronic Control Unit, located in the
storage bay between the frame rails.
5. Disconnect the wiring from the alternator.
6. Do not connect welding cables to electronic control components.
7. Attach the welding ground cable no more than two feet from the part to be welded.
Battery Disconnect:
Located in the battery
compartment, curbside.
