Self Test Charging System Problems (Article printed in July issue of ERE.) This brief self-test will help you measure your understanding of the charging system. The style is the same as that used for A.S.E. certification tests. Each incomplete statement or question is followed by four suggested comple- tions or answers. In each case, select the one that best completes the sentence or answers the question. 1. A regulator controls alternator output voltage by regulating: A. sine-wave voltage B. battery voltage C. field current D. output current In an alternator, alternating cur- rent is converted to direct cur- rent by the: A. stator B. brushes C. rectifier D. regulator If the charging system indicator lamp goes on with the engine running, the cause may be loss of voltage at terminal: A. “TG” B. “§? Cc. 1” D. “PR With the engine not running and the ignition on, the charge lamp should light. If it doesn’t, this may indicate a: A. bummed out bulb B. grounded bulb C. loose drive belt D. overcharged battery Which alternator terminal can be grounded for test purposes? A. “BR” B. “IG” C. “SO” D. “PR” When performing a_ visual inspection of the charging sys- tem, the alternator drive belt should be checked for proper tension. Technician ‘A’ says that new-belt tension specs are high- er than those for used belts. Technician ‘B’ says that the belt tension is different for different Toyota models. Who is right? A. only A B. only B C. both A and B D. neither A nor B The amount of current the alter- nator must supply for ignition and accessories is about: A. four amps B. six amps C. eight amps D. ten amps In an alternator output test under load, the output should be: A. about 10 amps B. about 30 amps C. within 10 percent of rated output D. within 20 percent of rated output To check for excessive voltage drop on the insulated side of the alternator’s output circuit, you would connect a _ voltmeter between the: A. battery terminal and ignition switch B. battery terminal and ground C. battery terminal and alterna- tor “S” terminal D. battery terminal and alterna- tor “B” terminal 10. High resistance in an alternator output circuit is often caused by: A. a discharged battery B. a shorted diode C. loose or corroded connections D. a bad regulator “UOISSILUJEd YM peyudey EI] ENE] “SUON]OOUUOD PapO.LI0d JO asoo, Aq pasnes ATaxI] SOUT SI 9OURISISOI DAISSOOXY—,..D,, ‘Ol “[PUIULIO} (q) jndjno Joyeussy[e oy) pue [eUTLUIO} (+) s,Ara}eq OY} 0} sped] 19}OUI[OA ay} yoouuos ‘doip a8eI[OA JMIIIO Poye[NsuI sy} 10} YOoyD OJ —..dI,, °6 ‘qndyno payel Jo UI -Iod Q] UlIM oq prnoys SuIpeor oy} “ndjno wnurxeu je Sul -yelodo JoyeuIaye oy) WIM—..D,, “8 “saLlossaoor pue uoniusi 10} Ajddns ysnu Joyeusaye oy) jUoLINS Jo JuNnowR oy) st sty ‘sdwe xis ynoqe oq plnoys Surpeor oy,—..d,, “L “SJOPOUL JUSIOFJIP 1OF JUDIOJJIP oe SULIYO JO spouysy ‘asn SULINP SUIOS Yd}ONS [[IM I asnesaq ‘j[9q pasn ve UY} UOTSUd} SIOW YIM Pofeysur St I] “soyNUTU OAL] UBY) SSoT JOJ pasn usaq sey TYP BO St .JJ9q MOU, YO,” ‘JJO ouIsus oy} YIM UdAd ‘SOUT []e Je JUaSoId ose -yoa Arayeqg sey I ./g,, [PUULIE} jndjno JOyeUIN}[e PUNOIS IOAN ‘popunols oq ued yey) [eUTUe) ATUO oy) ST 4, TeUTMUIAT—..q,, ° ‘IOJe[NSI JO Avpar AyNey JO ‘suo -o9uU0d asoo] ‘due, no pong ‘asnj UMOTG & OpnpoUT sasneo g[qissod ou) ‘suruuNI jou oUIsUS 2U} NO UOnTUST ot YIM “WYST] JOU soop dure] Ssurumem 94) JI—.V,, * ‘uo soos due] sur -UIRM OY} ‘po}soUUODSIp oUIOD0q (..q,, [eurutta}) jndjno sJoyeusaye ay) Jo (..S,, [eurue}) Iosuas JoyeNSa1 ayy JOYS JI— A. * ‘uoQoeIIp auo ATUO ur ssed 0} JUOLIND MOTTE Yorum SOPOIp JO JOS PB ‘IOlJNOOI oy) Aq jUaLIND JOoIIpP O}UL posueyo SI yUOLIND SuNneUIDe sy .—..D,, ° “THOS platy IOJOI dy} 0} ATONe OY) WOT, JUST -Ind Jo yUNOUTe ay) SUISvaIDOp IO suisvorour Aq yndjno Jo;eUIAI[e sjomuod IoyNsel syE—..D,, ‘T SUYHMSNV LSAL A TAS
