What's wrong?
The 2016-2017 Crestline Coach Icon 2.0 Ambulance uses a Magnum 1000W Model MMS 1012 inverter in the ambulance conversion electrical system. The inverter changes stored battery power into AC power for equipment that needs household-style current. It is supposed to stay connected to the conversion batteries while it is operating, so the electrical load stays controlled.
On affected ambulances, the operating mode can disconnect the inverter from the conversion batteries while the inverter is still running. That exposes the inverter to excess AC ripple current from the chassis electrical system or customer equipment loads. The inverter is sensitive to that ripple, and the internal electronics can fail, overheat, and, if the condition is not found, start a fire in the electrical compartment.
Owners or operators can see repeated inverter shutdowns from over-temperature or overload conditions. Other warning signs include an acrid burning odor, smoke, visible damage or discoloration on the inverter case, or heat damage on internal inverter components.
