Yuav ua li cas mus kuaj ib tug magneto kauj nrog ib tug multimeter
Txheem
Nrog cov tsheb niaj hnub, tsis muaj qhov kawg ntawm qhov teeb meem tuaj yeem tuaj.
Txawm li cas los xij, cov tsheb qub thiab cov cav tov yog lwm qhov kev xav txog; magneto coils.
Magneto coils yog cov khoom tseem ceeb hauv qhov hluav taws xob hluav taws xob ntawm cov dav hlau me me, tsheb laij teb, cov tshuab txiav nyom, thiab lub cav maus taus, thiab lwm yam.
Ntau tus neeg tsis paub yuav ua li cas los xyuas cov khoom no rau cov teeb meem, thiab peb nyob ntawm no los pab.
Hauv phau ntawv qhia no, koj yuav kawm cov hauv qab no:
- Magneto coil yog dab tsi thiab nws ua haujlwm li cas?
- Cov tsos mob ntawm Bad Magneto Coil

Magneto coil yog dab tsi thiab nws ua haujlwm li cas?
Magneto yog lub tshuab hluav taws xob uas siv cov hlau nplaum tas mus li los tsim cov pulses raws sij hawm thiab muaj zog tam sim no, tsis yog muab nws tas li.
Los ntawm nws cov coils, nws siv lub zog tam sim no mem tes rau lub txim hluav taws xob, uas ua rau cov roj compressed hauv lub cav qhov hluav taws xob tswj qhov system.
Lub zog no tsim tau li cas?
Muaj tsib yam uas ua haujlwm ua ke los ua kom muaj lub zog magneto:
- Armature
- Thawj ignition kauj ntawm 200 tig ntawm cov hlau tuab
- Ib tug thib ob ignition kauj ntawm 20,000 lem ntawm nplua hlau, thiab
- Hauv chav tswj hluav taws xob
- Ob lub zog hlau nplaum yog tsim rau hauv lub cav flywheel.
Lub armature yog U-zoo li lub caij nyob ib sab ntawm lub flywheel thiab nyob ib ncig ntawm uas ob lub magneto ignition coils raug mob.
Raws li Faraday txoj cai, txhua tus txheeb ze txav ntawm ib lub hlau nplaum thiab cov xaim induces tam sim no thiab ntws hauv cov hlau.
Lub cav flywheel muaj ob lub hlau nplaum embedded ntawm ib qho chaw tshwj xeeb.
Thaum lub flywheel rotates thiab qhov taw tes no hla lub armature, magnetic teb los ntawm cov hlau nplaum yuav siv sij hawm rau nws.
Nco ntsoov tias cov coils ntawm cov hlau yog nyob ntawm thauj tog rau nkoj, thiab raws li Faraday txoj cai, qhov chaw sib nqus no muab cov coils nrog hluav taws xob.
Ntawm no koj tuaj yeem pom yuav ua li cas rau txoj kev xaim.
Lub sij hawm no cov khoom tam sim no accumulates nyob rau hauv lub coils thiab ncav cuag qhov siab tshaj plaws.
Thaum qhov siab tshaj plaws no tau mus txog, lub tshuab hluav taws xob tswj hluav taws xob qhib qhov hloov thiab cov neeg sib cuag qhib.
Qhov surge tam sim no xa cov hluav taws xob muaj zog rau lub txim hluav taws xob, pib lub cav. Txhua yam no tshwm sim hauv ob peb feeb.
Tam sim no lub magneto yuav tsis ua hauj lwm rau nws lub hom phiaj zoo, thiab coils feem ntau yog tus txhaum.
Cov tsos mob ntawm Bad Magneto Coil
Thaum lub magneto coil faulty, koj muaj cov hauv qab no
- Lub check engine teeb los ntawm lub dashboard
- Nyuaj pib lub cav
- Ntau qhov deb tau taug kev los ntawm cov pa roj
- Tsis muaj zog acceleration
Yog tias koj pom ib qho ntawm cov no, cov hlau nplaum coils yuav yog qhov teeb meem.
Raws li nrog rau kev sim lwm yam khoom siv hluav taws xob thiab cov khoom siv, koj yuav xav tau ib lub ntsuas ntsuas los ntsuas cov coils.
Yuav ua li cas kuaj lub magneto kauj nrog multimeter
Tshem cov roj hmab shroud, teem lub multimeter rau ohms (ohms), thiab xyuas kom meej tias qhov ntau ohm yog teem rau 40k ohms yam tsis muaj autoranging. Muab cov multimeter probes rau ntawm tooj liab winding ntawm lub magneto thiab hlau clamp nyob rau hauv cov roj hmab casing. Txhua tus nqi hauv qab lossis siab dua ntawm 3k mus rau 15k ntau txhais tau tias cov hlau nplaum hlau tsis zoo.
Qhov no tsuas yog qhov yooj yim tshaj plaws thiab cov lus piav qhia ncaj qha ntawm qhov koj yuav tsum tau ua, thiab xav tau kev piav qhia ntxiv kom nkag siab txog cov txheej txheem.
- Disconnect lub flywheel vaj tse
Thawj kauj ruam yog kom tshem tawm cov vaj tsev flywheel los ntawm tag nrho cov teeb tsa.
Lub flywheel vaj tse yog ib qho hlau casing uas npog cov hlau nplaum thiab tuav nyob rau hauv qhov chaw los ntawm peb bolts.
Cov cav ua nyob rau xyoo 1970 feem ntau muaj plaub bolts tuav lub shroud nyob rau hauv qhov chaw.
- Nrhiav cov magneto coil
Tom qab lub shroud raug tshem tawm, koj yuav pom lub magneto kauj.
Nrhiav cov magneto coil yuav tsum tsis txhob muaj teeb meem, vim nws tsuas yog ib feem tom qab lub shroud nrog raug tooj liab windings los yog ib tug hlau core.
Cov tooj liab windings (armature) tsim U-puab.
- Tshem cov roj hmab npog
Lub magneto coil muaj cov xov hlau tiv thaiv los ntawm cov roj hmab casing uas nkag mus rau hauv lub qhov hluav taws xob. Txhawm rau kuaj qhov no, koj yuav tsum tshem tawm cov khau raj roj hmab no los ntawm lub tshuab hluav taws xob.
- Teem lub ntsuas multimeter
Rau lub magneto kauj, koj ntsuas qhov tsis kam. Qhov no txhais tau hais tias koj lub xov tooj multimeter yog teem rau ohms, sawv cev los ntawm lub cim omega (Ω).
Es tsis txhob autoranging, koj manually teem lub multimeter rau 40 kΩ ntau. Qhov no yog vim tsis siv neeg ntau yam muab cov txiaj ntsig tsis txaus ntseeg.
- Txoj hauj lwm ntawm multimeter probes
Tam sim no, txhawm rau ntsuas qhov kev tawm tsam hauv cov hlau nplaum, ob yam yuav tsum tau ua. Koj xav ntsuas lub hauv paus thiab theem nrab coils.
Rau thawj kauj ruam, tso cov hlau xeem liab rau ntawm U-shaped winding thiab hauv av qhov kev sim dub ua rau cov hlau nto.
Txhawm rau ntsuas qhov ntsuas cua thib ob, muab ib qho ntawm cov ntsuas ntsuas ntsuas ntawm U-shaped hlau core (winding), thiab ntxig rau lwm qhov kev sojntsuam rau hauv cov roj hmab casing ntawm lwm qhov kawg ntawm cov hlau nplaum.
Thaum qhov kev sojntsuam no nyob rau hauv lub tsev roj hmab, xyuas kom nws kov cov hlau clip rau nws.
Ntawm no yog ib daim vis dis aus uas qhia tau hais tias yuav ua li cas ntsuas lub ntsiab thiab theem nrab magneto coils.
- Ntsuas cov txiaj ntsig
Tom qab cov kev sojntsuam tau muab tso rau ntawm qhov sib txawv ntawm cov magneto, koj xyuas qhov kev nyeem ntawv multimeter.
Kev nyeem ntawv yog nyob rau hauv kiloohms thiab yuav tsum nyob nruab nrab ntawm 3 kΩ thiab 15 kΩ, nyob ntawm seb hom magneto raug kuaj.
Kev xa mus rau cov chaw tsim khoom phau ntawv yuav pab koj nrog qhov no. Ib qho kev nyeem ntawv sab nraud ntawm qhov ntau no txhais tau hais tias koj lub magneto coil tsis zoo.
Qee lub sij hawm lub multimeter tuaj yeem tso saib "OL", uas txhais tau hais tias muaj qhov qhib Circuit Court lossis luv luv ntawm ob lub ntsiab lus no. Nyob rau hauv txhua rooj plaub, lub magneto coil yuav tsum tau hloov.
Ntxiv rau cov no, muaj qee cov lus qhia uas koj yuav tsum tau them sai sai rau.
Yog hais tias lub multimeter nyeem saum toj no 15 kΩ, kev sib txuas ntawm high voltage (HV) xaim ntawm lub kauj thiab cov hlau clip uas mus rau lub txim hluav taws xob yuav yog tus txhaum.
Yog tias tag nrho cov no raug kuaj xyuas thiab cov hlau nplaum qhia qhov tseeb kev nyeem ntawv, ces qhov teeb meem tuaj yeem yog lub txim hluav taws xob lossis cov hlau nplaum tsis muaj zog hauv flywheel.
Xyuas cov khoom no ua ntej txiav txim siab hloov cov magneto.
Cov lus nug nquag nug
Yuav tsum muaj pes tsawg ohms lub ignition coil?
Ib qho zoo magneto coil yuav muab kev nyeem ntawv ntawm 3 txog 15 kΩ ohms nyob ntawm tus qauv. Txhua tus nqi hauv qab lossis saum toj no qhia tau tias muaj kev ua haujlwm tsis zoo thiab koj yuav tau hloov nws.
Yuav ua li cas kuaj magneto rau txim?
Txhawm rau kuaj cov hlau nplaum rau lub txim, koj siv lub txim hluav taws xob. Txuas cov hlua khi ntawm qhov ntsuas hluav taws xob no rau lub tshuab hluav taws xob magneto, sim tig lub cav thiab saib seb lub ntsuas ntsuas no flashes.
Yuav ua li cas kuaj ib lub tshuab me me nrog lub multimeter
Cias tso lub multimeter's leads rau ntawm "U" zoo li tus hlau core thiab lub txim plug lub hlau clamp ntawm lwm kawg. Kev nyeem sab nraum qhov ntau ntawm 3 kΩ txog 5 kΩ qhia tias nws muaj kev puas tsuaj.
Yuav ua li cas koj kuaj lub magneto capacitor
Teem lub 'meter' rau ohms (ohms), tso cov hlau kuaj liab rau ntawm qhov kub sib txuas, thiab hauv av qhov kev sim dub ua rau lub ntsej muag hlau. Yog tias lub capacitor tsis zoo, lub 'meter' yuav tsis muab kev nyeem ntawv ruaj khov.
Muaj pes tsawg volts lub magneto tso tawm?
Ib tug zoo magneto tso tawm txog 50 volts. Thaum lub kauj yog ntxig, tus nqi no nce mus rau 15,000 volts thiab tuaj yeem ntsuas tau yooj yim nrog lub voltmeter.
