What's wrong?
The A/C input power cord on the 2018 Aev Traumahawk ambulance feeds power to the Sensata inverter. The inverter helps convert and manage electrical power for equipment on the ambulance, so the cord has to match the electrical load it carries.
In affected Traumahawk ambulances, the input power cord is undersized for the inverter application. That means the cord is not matched to the power demand Sensata identified in its Magnum Energy MM-MMS inverter service bulletin. The mismatch can create an electrical short circuit in the inverter power circuit.
There is no warning sign before failure. The ambulance's electrical equipment can appear normal until the short circuit happens, so symptoms are not a reliable way to decide whether this recall applies.
