Checking Fleetwood’s website for the owners manual, on page 08-07 it mentions under drivers side of dashboard are additional chassis related fuses. Also check the wiring harness connection, as these tend to see a lot of vibration, and work loose, or develop corrosion making intermittent or lost electrical connections. Also in July on the FMA Facebook forum an individual reached out to Fleetwood with their year, make, model and VIN information and got detailed information on wiring, so you may try that route (see photo).
Please keep us posted on the outcome.
MOTOR HOME FUSES AND
CIRCUIT BREAKERS
The 120-volt circuit breakers and l2-volt fuses
are located on three separate panels. The pur-
pose of these three panels is to provide electrical
circuit breakers and fuses to interrupt current
flow if a circuit is overloaded.
1. 120-volt House Electrical- This electri-
cal panel is located under the bed. This
panel is very similar to a residential panel
with resettable breakers.
2. Fleetwood Automotive 12-volt System -
This panel is located on the driver's side
under the hood. This electrical center con-
tains battery disconnect systems, entry step,
fog light, and some other automotive circuitry.
3. 12-volt Chassis Fuses - This electrical
panel is located under the driver's side dash
area .
