In the last of the last lesson you saw ho wthepart water of the electrolyte constantly decomposes and disappears In the form of baa For this reason, about once a wreck you should fill the battery with distilled (not f.lterel water.

Do not attempt to teat the battery after filling with water Never put acid Into the battery.

' When the, electrolyte Is first poured Into the battery much of the sulphuric acid will be absorbed by the plates, and so the electrolyte becomes lighter In weight, the proportion of acid to water becoming leas. As the battery Is charged, however, the sulphurlo acid is thrown out of the plates and Into the electrolyte again, thus making theIs eelctrolyte As the battery heavier. discharged the acid will again be absorbed and the electrolyte become lighter. Here, then. Is a way In which to see 22. 15 22, 1921. umiumsuuu uoouumjooo u u u - s BMWi U uu u u u u u u u u uu u u u u u uu u u u u u u u II u u u u u U 1 uuuuuuuuuuuuuuuouuuu Correct lubrication i3 a vital, consideration in either case. - how well charged the battery la, namely, -by weighing the electrolyte. The best way to weight the electrolyte Is by means of a hydrometer. This Is a glass tube asmade airtight, having some lead shot weight in the bottom, and having a scale of numbers In the top. 1 shows a hydrometer. Figure The hydrometer Is so weighted and proportioned that when placed In pure a depth as aster It will sink to such come to the to h e the top of the water 1000 mark on the scale, as Figure 2. The very top Is the 1000 mark of many hydromaters.' If placed tn a liquid heavier than water it will not sink so' far, and the number to which the top of the liquid comes will give the weight of the liquid as compared to the weight of water. Thus the liquid In Figure 3 weighs 1.3 as much as water does. Bo. then to test a battery to eee how the charge Is, draw out some of the elecIt a hydrometer. trolyte and place Into When the reading Is: 1 275 to 1.3 battery Is fully charged. 1,20.. battery Is charged 1.210 battery Is half charged. 1 100 te charged. battery 1 120 battery la discharged. A special hydrometer syringe with which the electrolyte can be drawn out of the battery, and also containing the hydrometer, can be purchased at any accessory store, and will provs a handy device to have. While you can test a battery of dry rails with an ammeter, you cannot do this In the case of a etorage battery. In the first case the amperage Is seldom over must be connected to the positive of the battery, and the negative to the negative. The voltage of the charging current should be somewhat greater than that of the battery, while the amperage h of the should tiot be above capacity. When a battery Is charged or discharged very quickly It will overheat, and this overseating may result In the plates warping When the plates warp the pasts will fall out of the grida Not only will this prevent the battery from taking a. charge, but It will short circuit the plates at the bottom. For this reason the battery must be charged slowly. Using the starting motor tor a considerable time at a stretch means a quick discharging of the battery and a possible overheating and warping. Therefore, If the engine does not start quickly, do not use the starter for a long time, but get out and find out why the engine does not one-tent- ftart. Keep your battery clean. If the smallest quantity of iron or copper, etc., gets Into the battery, an Iron or copper sulphate will form on the plates and so make them Inactive. . Do not leave a battery standing in a discharged state for any length of time. It Is a good practice to wipe the terminals with a cloth on which there Is a little vaseline. Acid must neter be put Into the battery. If the electrolyte Is spilled by accident. the battery must be refilled with a solution of acid and water. It le beet to let the battery man do this for you. When you disconnect the battery wrap the terminal wires In Insulating tape. three-fourt- one-four- th Motor Trucks in 1920 j MOTOR TRUCK TIPS j Spare Plugs. Truck operators will find it economical to have spare spark plugs wrapped In sections of old Inner tubes, with rubber bands at top and bottom to hold the plugs snug. Many spark plugs are broken in the tool box before they have even been used. The Basie of a Delivery System. It Is an axiom among truck operators that the gone la the basis of the delivery system.
