| RR 788 (10M) (8489. 24-10-30) 6/3188. ORIGINAL COMPLETED 28. 1. 32. STANDARDISATION of CHASSIS PARTS. Date 15.10.31 No. 7720 Drawing No. Part List Description of Parts. BALLAST RESISTANCE WITH VITREOUS INSULATOR IN ONE PIECE AND THE WIRE FASTENED MECHANICALLY TO TERMINALS. Origin. The hard soldering operation of joining the wire has proved unsatisfactory, breakages have occurred in service. Experimental Test Report. Road Test Report. This method of connection is considered to be much superior to the old as it requires considerable skill and experience to ensure that the brazed joint remained satisfactory in service. Used satisfactorily on 25-EX for 22,000 miles. [STAMP: PHANTOM II 20/25 H.P. CHASSIS] A Scrap and replace at all costs including Chassis already delivered to Customers. B Scrap and replace on Chassis in Works. C Scrap present stock and replace on all Chassis not yet handed to test. D Use existing stock Alteration effective on future Chassis. Weight of Old Part.
