Which of the following most accurately describes the problem?

• To meet the electrical power requirements of a super VIP coach shortly to be introduced by London operator Best and Sons, Ealing, London W5, the AEC Reliance chassis on which it will be based has been fitted with two CAV AC 203 alternators. The installation provides an electrical output of 120amp at 24V—well in excess of the load imposed by the internal lighting, air circulating fans, catering equipment, television, radio and tape recorder, PA system and shaver points, in the coachwork being constructed by Van Hool of Belgium.

The coach will be equipped with 28 seats, a conference area, cocktail bar, toilet and washing facilities and a bedroom for use by the second driver, which will be incorporated at the rear of the vehicle. Full refrigerated air conditioning has been specified and a heating system provided by an independent diesel fired unit.

Ealing Auto Electrical, Trumpers Way Trading Estate, Hanwell, London W7, Lucas/CAV main agents, undertobk the installation. The two totally enclosed alternators are both cradle mounted and carried by chassis cross-members. Each is shaft driven from the engine through power transfer boxes.

Two sets of batteries of 150 and 195 Ah are incorporated which are charged by both alternators through Lucas blocking diode units. In this way maximum alternator output can be more efficiently used as required and the starter battery is prevented from being discharged by the auxiliary loads when the engine is not running. To prevent interference to the audio equipment carried, the complete charging systerp is suppressed to BS1597/1963 with CAV marine suppression equipment.
