| RR 758 (10M) (30405. 21.4.32) BM. S/8362/4. ORIGINAL COMPLETED 28.9.33. STANDARDISATION of CHASSIS PARTS. Date 24.9.32. X No. 6142 X No. 6092 Drawing No. Part List Description of Parts. R.R. SHUNT DYNAMO CONTROLLED BY C.A.V. TYPE B2 CONSTANT VOLTAGE VIBRATOR REGULATOR. Origin. To allow dynamo output to be governed by the demands of the battery. Experimental Test Report. A series of Bench tests have shewn this regulator to function satisfactorily. It is the best British regulator in existence. Road Test Report. This system ran 15,000 miles only-EX. without any failure of the regulator. Weight of Old Part. Cost of Old Part. £ 11.0.0. Weight of New Part. Cost of New Part. £ 13.1.8.
