Electronic Noise Suppressor: Description and Operation
Suppression Module
Although the output from the generator is finely controlled and relatively smooth, it is still a pulsed DC output at a varying frequency proportional to
engine speed.
The suppression module damps out any ripple which may be sensed on the main output of the generator. This prevents possible interference via the
power supply, affecting the radio reception or, where fitted, the telephone.
The module is located on the right hand side of the engine compartment, on the inner panel just above the chassis leg, adjacent to the generator. It is
secured to two anti-vibration rubber mountings. The image shows the suppression module viewed from below the vehicle.
A fuse is fitted internally to the suppression module to protect the generator output in the event of a short circuit within the suppression module.
