Electronic Noise Suppressor: Description and Operation

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 adjacent to the generator. It is secured to a mounting bracket by three bolts. The mounting bracket is bolted to the inner panel, just above the chassis leg. The illustration 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.
