Show AUTO BATTERY TROUBLE TOLD Corrosion Is Chief Cause of Difficulties Says Expert Bj H. CI 'i i ' -I BROK W$, Technical iJiwt6r. West Side V. M. C. k'atbmbWW SchablSi New York. The. battery of an automobile, like thai of an artillery outfic or a baseball base-ball team, does not always COfne up to tho expectations of the people In charge of P. The chief source "f battery troubles is corroded terminals, very of( n iu- liKhtx. horn ami intuition will operate sutlsf ir tnrll but the self starter will not. This mav be traced to corrodeu or poorly fitting battery terminals, .which will allow a sufficient amount of current to pass to operate the lights and horn. However, as the starting motor takes many times the amount of current used by these other devices, the resistance may be great enough to prevent this motor from operating operat-ing Corrosion Is formed by the action of the electrolite or acid In the battery After It has formed the most satisfactory satisfac-tory way to get rid of It Is to 8i rape the terminals until there Is a UrlRht finish. WiLshlnK th. terminals with ammonia or Borne other alkaline solution will neutralise any acid that may ho present and prevent corrosion. When such washing Is done care Should be taken that none of this solution solu-tion g' ts Into the battery, as It will neutralize the acid In the battery and stop its action. After the terminils have been scraped, cleaned and brightened and : the parts have been assembled, caro should he taken to see that the ter- t in m. ils make contact for the full area of their Surface. If the corrosion become too pre.it t or If the contact from any other rea- son becomes poor the lights are apt ' to flare up to excessive brightness, and if the contact is so poor that no current can pass, or If the win should become disconnected from the bat- 1 tery, tho lights will burn out entirely 1 in most systems. This Is because the generators which charges the battery 1 Is designed to deliver sufficient cur- 1 rent to charge the batten.- at low speed, and when the engine is speeded speed-ed up It will deliver much more than ( Is necessary. |
