TROUBLESHOOTING THE 12-VOLT SYSTEM
1. The coach battery may be low (this can be checked at the monitor panel). You may
charge your coach battery by simply running the chassis engine. If the coach
battery wont hold a charge, contact a qualified service technician to test the battery
and charging system.
2. A fuse may be bad. Replacement fuses may be purchased at auto parts stores,
hardware stores and some service stations.
3. The 40AMP circuit breaker may need to cool down or be reset. Depending on the
model, you must push the reset button. On other models the breaker resets
automatically (no reset button). The reset button is often on the back side of the
breaker box and can be felt but not seen.
4. If the breaker fails and will not reset, there is an electrical overload or other
problem and you must contact a qualified service technician to evaluate and repair.
5. A rotten egg odor in the coach indicates sulfur fumes which are probably coming
from the coach battery because of over-charging or a short. Open all windows in
the motorhome and contact an authorized service technician to arrange for service
and repair.
