No maintenance - CAT3 has only THREE parts in total.
1
The vehicle battery.
This provides all the energy required by CAT3. A fail-safe device automatically switches
the system off before the battery level becomes too low to start the vehicle.
2
The CAT3 generator.
This unit modifies the power produced by the battery into a constant "stream" of free
electrons that operate the system.
3
The CAT3 sensor.
The sensor(s) transfer the stream of free electrons to the metal body of the vehicle. While in
operation this will produce a constant purring sound. (4x4 vehicles and larger motor homes require 2 sensors).
