Lub tshuab hluav taws xob siv los siv tag nrho cov cuab yeej hluav taws xob hauv lub tsheb tom qab pib lub cav. Nws yuav tsum nyob hauv qhov xwm txheej zoo, txij li qhov them tseeb ntawm lub roj teeb yog nyob ntawm nws txoj haujlwm. Ib qho ntxiv, lub tshuab hluav taws xob ua rau nws muaj peev xwm txuas ntxiv rau ntau qhov sib txawv ntawm cov khoom siv sib txawv thiab cov khoom siv rau hauv lub network. Nws cov kev pabcuam kev ua haujlwm yuav tsum tau kuaj xyuas tsis tu ncua. Koj tuaj yeem tshawb xyuas lub tshuab hluav taws xob nrog multimeter lossis ntawm qhov tshwj xeeb sawv.
Nws yog qhov tsim nyog

Cov Lus Qhia
Kauj ruam 1
Kos rau lub regulator relay. Nws pabcuam kom tswj hwm tus nqi hluav taws xob zoo tshaj plaws hauv lub tsheb ntawm cov pawg ua haujlwm. Lub relay-regulator tsis pub nws nce mus rau theem tseem ceeb. Pib koj lub tsheb. Muab multimeter hloov mus rau hauv "kev ntsuas hluav taws xob" hom. Ntsuas cov khoom siv fais fab rau hauv on-board network. Qhov no tuaj yeem ua tiav ntawm lub tshuab hluav taws xob tsim tawm lossis ntawm cov roj teeb. Nws yuav tsum nyob ntawm thaj tsam ntawm 14-14, 2 V. Nias tus tsuj roj. Txheeb xyuas qhov kev nyeem dua. Yog tias qhov hloov hluav taws xob tau hloov ntau dua li 0.5 V, ces qhov no yog qhov taw qhia ntawm kev ua haujlwm tsis zoo ntawm lub ntsuas hluav taws xob relay.
Kauj ruam 2
Kuaj cov diode choj. Nws muaj rau (diodes). Peb ntawm lawv yog qhov zoo thiab peb yog qhov tsis zoo. Muab lub multimeter hloov mus rau "suab" hom. Tam sim no, thaum cov neeg siv khoom sib txuas raug kaw, lub squeak yuav tau hnov. Xyuas ob qho tib si rau pem hauv ntej thiab sab nraud. Yog tias squeak tau hnov hauv ob qho xwm txheej, tom qab ntawd lub diode tau tawg thiab yuav tsum tau hloov.
Kauj ruam 3
Xyuas lub tshuab hluav taws xob stator. Nws yog cov hlau kheej kheej, sab hauv uas cov cua ntsaws tau muab tso rau hauv txoj kev tshwj xeeb. Txhawm rau tshawb xyuas, txiav tawm cov stator ua los ntawm tus choj diode. Tshawb xyuas cov xwm txheej ntawm qhov winding rau kev puas tsuaj tshuab thiab kub. Tso rau multimeter rau hauv "kev ntsuas ntsuas" hom. Txheeb xyuas qhov ntsuas cua kom tawg. Txhawm rau ua qhov no, nias ib qho kev tiv tauj ntawm tus simter rau cov tsev stator, thiab lwm qhov mus rau ib qho ntawm qhov ntsuas cua. Yog tias qhov tawm tsam ntxiv rau infinity, ces nws yog kev pabcuam. Nyeem tsawg dua 50 KOhm ceeb toom ntawm qhov yuav pib lub tshuab hluav taws xob.
Kauj ruam 4
Xyuas lub tshuab hluav taws xob rotor. Nws yog cov pas hlau uas txuas ntawm qhov sib dhos uas raug mob. Ntawm ib kawg ntawm nws muaj cov hlua khi ntawm qhov uas txhuam txhuam zawv zawg. Tom qab hle lub rotor, tshuaj xyuas tus kabmob ntawm cov kabmob thiab lub rotor winding. Txheeb xyuas kev ncaj ncees ntawm daim teb winding. Tso rau multimeter rau hauv "kev ntsuas ntsuas" hom. Ntsuas tus nqi ntawm ob lub voj voos. Yog tias tawm tsam tsawg tsawg, ces cua tshuab tau zoo. Kuaj xyuas kom ntxaws ntxaws ntxiv rau ntawm phab ntsa ntsuas tshwj xeeb ntawm chaw nres tsheb tshwj xeeb chaw haujlwm.
