Sec. 8.

(a) The alternator and rectifier must have a minimum output capacity of 80 amperes. If the bus has a passenger capacity of more than 36, the output capacity must be at least 100 amperes. A single belt drive is permissible.

(b) The battery must be conventional (lead-antimony) or maintenance free sealed (lead-calcium). Each battery system must be twelve (12) volt with at least 430 CCA (cold cranking amperes) per J-537h specifications. If the bus has a diesel engine, the battery system must have a minimum of 900 CCA. If the battery is mounted outside of the engine compartment, it may be temporarily mounted to the chassis. One piece battery cables, SAE J-541, that are at least 36 inches longer than normally required to accommodate the battery when located 52 inches to the rear of the cowl, must be used.

(c) The chassis must be equipped with the following instruments and gauges:

(1) speedometer;

(2) odometer which will give accrued mileage, calibrated in tenths of miles;

(3) voltmeter or ammeter;

(4) oil pressure gauge;

(5) water temperature gauge;

(6) fuel gauge;

(7) upper beam headlamp indicator; and

(8) brake warning light.

All instruments must be easily accessible for maintenance and repair. The instrument panel must have lamps of sufficient candlepower to illuminate all instruments and gauges.

(d) All wiring must conform to the manufacturer's standards and to the standards of the Society of Automotive Engineers. The chassis manufacturer must install a terminal strip or plug on the body side of the cowl or in an accessible location in the engine compartment if the bus has no cowl that contains the following body connection terminals:

(1) main 100 amp body circuit;

(2) tail lamps;

(3) right turn signal;

(4) left turn signal;

(5) stop lamps;
