Cov teeb uas muaj cov duab ntawm cov roj teeb ntawm cov dashboard los txog. Tsis txhob ntshai, vim rau feem ntau lub malfunction lus dag nyob rau saum npoo. Txhawm rau tshem tawm nws, koj tsis tas yuav tshem lub tshuab hluav taws xob.
Nws yog qhov tsim nyog
- - multimeter;
- - tswj lub teeb;
- - xov hlau;
- - lub zog muab hluav taws xob nrog voltage regulator;
- - txheej ntawm cov yuam sij thiab ntsia hlau ntsuas.
Cov Lus Qhia
Kauj ruam 1
Saib ntawm lub teeb ceeb toom nyob rau ntawm cov chaw. Nws hom kev ua haujlwm yog xws li tias thaum lub qhov cub hluav taws xob, nws kub hnyiab, tab sis thaum lub cav khiav, nws tawm mus. Yog tias nws nyob qis qis tom qab pib lub cav, lub roj teeb tsis raug them. Txheeb xyuas qhov voltage nyob rau hauv on-board network nrog multimeter, nws yuav tsum tsis pub tsawg dua 12 volts. Vim li cas rau lub teeb ua kom pom kev tuaj yeem yog txoj hlua khi lossis cov xov hluav taws xob tawg. Yog tias lub teeb hlawv thaum tshav kub kub tas nrho, tom qab ntawd muaj qhov sib zog siv tsis tau. Hauv qhov no, koj tsuas yog xav tau ceev nws kom nruj rau lub xeev xav tau.
Kauj ruam 2
Kuaj fuse F2 yog tias txoj siv sia sib zog, tab sis qhov ntsuas hluav taws xob hauv lub network on-board yuav qis dua nws yuav tsum. Yog tias nws hlawv tawm, hloov nws, tom qab ntawv txheeb xyuas tus nqi ntawm lub roj teeb. Yog tias lub fuse ua haujlwm zoo, lossis tom qab hloov tsis muaj kev hloov pauv, thiab qhov ntsuas hluav taws xob hauv lub network on-board tseem tsis tshua muaj, nws yuav tsim nyog los ntsuas qhov voltage ntawm lub davhlau ya nyob twg 61. Nws tus nqi yuav tsum nyob ib puag ncig 6 ntim. Yog tias tsis muaj lub zog voltage, tom qab ntawd tshem tawm cov dashboard thiab nrhiav qhov ua haujlwm tsis zoo hauv cov ntsiab lus soldering, hauv qhov tsis kam, nws tseem muaj peev xwm ua kom xaim mus rau qhov dashboard los ntawm 61 qhov khoom tawm yooj yim.

Tshem tawm cov chaw tswj hwm lub zog yog tias qhov ntsuas hluav taws xob, tab sis nws ntau dua 6 volts. Txheeb xyuas nws nrog ntsuas teeb. Txhawm rau ua qhov no, koj yuav tsum siv lub ntsuas hluav taws xob ntawm 12 ntuag txuas mus rau relay-regulator. Thov ntxiv rau lub ntsaws txuas ntawm qhov kev tswj hwm, thiab rho tawm mus rau lub cev. Ib qho kev sim teeb tsa tau tsim rau lub ntsuas hluav taws xob ntawm 12 volts, nrog lub zog ua haujlwm siab txog 3 watts, txuas mus rau txhuam ntawm cov ntsuas kev tswj hwm. Ntawm qhov ntsuas hluav taws xob ntawm 12 volts, lub teeb tswj yuav ua kom pom kev. Txhawb cov roj hluav taws xob rau 16 volts. Lub teeb yuav tsum tawm mus. Yog tias qhov no tsis tshwm sim, ces cov relay-regulator yog faulty. Tab sis yog tias nws tuaj yeem siv tau, tab sis tsis tau them nqi, ces koj yuav tsum tshem tawm lub tshuab hluav taws xob thiab saib seb puas muaj qhov tawg hauv nws.

Txheeb xyuas lub tshuab hluav taws xob rotor winding nrog multimeter. Lub tshav pob winding yuav tsum muaj qhov tsis kam ntawm 4.5 ohms. Yog tias nws tsawg dua, tom qab ntawd tag nrho malfunction lus dag hauv nws. Hloov lub armature, lossis rewind winding. Nws yog tau hais tias cov hlua khau khiab yog qias neeg. Huv si, yaug nrog cov kuab tshuaj, lossis hloov. Yog hais tias tus multimeter tseem qhia tau hais tias muaj kev qhib Circuit Court hauv lub rotor winding, hloov rotor. Tab sis yog tias txhua yam nyob rau hauv kev txiav txim nrog lub rotor winding, tom qab ntawd txheeb xyuas yog tias muaj luv luv nruab nrab ntawm 30 tso zis ntawm lub tshuab hluav taws xob thiab rooj plaub. Yog muaj, ces koj yuav tsum tau muab tshem tawm.

Kev kuaj xyuas lub twj tso tawm (rectifier) yog tias tsis muaj luv luv nruab nrab ntawm thaj av thiab lub davhlau ya nyob 30 ntawm lub tshuab hluav taws xob. Ua li no, koj yuav tsum tau kuaj txhua lub diode rau kev tawg. Lub tshuab hluav taws xob semiconductor coj hluav taws xob nyob rau hauv tsuas yog ib qho kev taw qhia, raws li cov cuab yeej no, diodes tau txheeb xyuas. Yog tias ntau qhov diodes tau hlawv tawm thiab nws tsis tuaj yeem rhuav tshem qhov tawg ntawm chav tsev rectifier, tom qab ntawd hloov nws kiag li. Tab sis yog tias cov cuab yeej ua haujlwm tau zoo, tom qab ntawd xyuas cov stator winding rau luv Circuit Court thiab qhib kev ua haujlwm.
