Fowler Clarke - Electrical Engineer} P.N 23/ Typed text: Stl/TB/14.6.23 To H. {Arthur M. Hanbury - Head Complaints} from St. {Capt. P. R. Strong} Referring to my Memo No. 5057 on Ch. 17-JG., Eccles, and Memo Re. Chassis 37-UG., Carlyle, both of which deal with the results of running these cars with the small lead loose upon the positive terminal of the battery. Although I fancy this state of affairs is uncommon, its occurrence, besides being a source of trouble, may seriously injure the battery, and I imagine produces a risk of fire. Is not some slight alteration advisable to overcome this defect? For instance, the large and small leads from the battery might be permanently connected so that only one wire has to be attached to each of the two battery terminals. Alternatively, the two wires from the button switch to the main switch and actuator box might be divided and only connected upon application of the button switch. Or again, a separate lead might be taken to the coil of the main switch instead of tapping the main supply of the starter motor. St. {Capt. P. R. Strong} | ||
