| -2- THE FIRST CHARGE. "The first charge........................ ........................ plates (see Diagram 3). Acid Level and Specific Gravity. "At the end of........................ ........................ 168 ... 66. Effect of Temperature on Specific Gravity of Acid. "The figures given........................ ........................ 100°F.{Mr Friese} .016" {.016 being put in place of .015.} "The first charge........................ ........................ the electrical system. It should be securely packed in its box (by means of the wedges provided) so that it cannot move, and the cable terminals, after being connected up, should be thoroughly smeared all over with pure vaseline. See that cell to cell connections are quite tight, and afterwards vaselined." {The reference to the vaseline being allowed to interfere with the metallic contact between terminals and connections is omitted as it has no interference when joints are properly screwed up.} {The matter under the side title "Use of Charging Switch" is purposely omitted as this matter, which refers to portions of the electrical system other than the battery, is included in Chapter 3. of the R.R. Instruction Book.} Maintenance of battery in service. {This side title takes the place of "Care of battery under running conditions"} "The top of the battery should always be kept clean and, as far as possible, dry; attention should be given immediately to the least sign of corrosion occurring on the terminals. | ||
