| To: DHQ C. EFC. X4008 BY/RD2/ML.15.12.27. BATTERY CHARGE CONTROLLER. X4008 It has been found that on the first of the three Battery Charge Controllers built up that the fixed contact point was not sufficiently rigid. On the remaining two that you are building, will you please have the ebonite base altered in accordance with 2495/D and fit the stiffer Contact Holder D.71513, this will need a new cable eye D.71514. We attach hereto a sketch shewing the assembly of these new parts, the two existing small holes can remain in the base and are of no consequence. We suggest that this contact holder be made by hand, as this only represents a temporary scheme. BY/RD. | ||
