Automotive Electronic Flasher Tus Nqi Hloov Kho

Rau txhua tus neeg uas tau ntxiv qhov muag teev LED rau lawv lub tsheb tig teeb lossis nres teeb.

Txij li cov qij LED siv Amps tsawg dua li cov qij ib txwm, chav flasher xav tias muaj lub teeb tawg thiab ua rau lub teeb nyem ob npaug. Cov lus qhia no yuav qhia koj yuav ua li cas hloov pauv lub teeb nyem hauv koj lub tsheb rau qhov hloov pauv nrawm. Nco tseg: Qhov no yog rau hom hluav taws xob xa hluav taws xob nkaus xwb. Qhov no yuav tsis ua haujlwm ntawm thermal flashers.

Kauj ruam 1: Flasher

Lub Flasher
Lub Flasher

Nov yog lub flasher kuv hloov kho. Txij li thaum kuv tab tom siv lub tswb nrov hauv kuv lub tsheb, Kuv nyuam qhuav rub qhov no tawm ntawm lwm tus '97 Cougar ntawm lub qhov rooj.

Muaj ob lub tab tuav lub rooj tsav xwm hauv, tsuas yog ntswj lawv xoob nrog tus ntsia hlau me me.

Kauj ruam 2: Sab hauv Flasher

Sab hauv ntawm lub teeb nyem yog yooj yim zoo nkauj. nws suav nrog qhib tus ncej xa tawm, ob peb tus tiv thaiv, lub tshuab hluav taws xob, tshem tawm, thiab tus tswj hwm IC. Kuv ntsia tus lej naj npawb kom pom cov duab.

Rau qhov tshwj xeeb flasher, 100k Ohm resistor txuas nrog tus pin 4 thiab 5 yuav raug tshem tawm thiab hloov pauv nrog 500k Ohm sib txawv resistor.

Kauj Ruam 3: Tshem tus Resistor

Tshem tus Resistor
Tshem tus Resistor

Tsuas yog desolder tus resistor los ntawm nws lub rooj tsavxwm. Ceev faj kom tsis txhob kub thiab hlawv IC.

Kauj Ruam 4: Hloov pauv Resistor

Kuj tsis paub meej Resistor
Kuj tsis paub meej Resistor

Ntawm no, qhov sib txawv tshiab resistor txuas nrog. Muaj peb tus pin ntawm qhov sib txawv resistor. Ob qhov kawg txuas rau 500k Ohm tsis kam. Lub hauv paus tus pin txuas rau lub wiper. Txuas ob lub xov hlau, ib qho rau lub wiper thiab lwm qhov rau ib qho ntawm tus pin sab.

Thaum koj teeb koj tus nqi nyem, koj tuaj yeem ntsuas qhov tsis kam ntawm qhov sib txawv resistor thiab hloov nws nrog tus tiv thaiv ruaj khov yog tias koj xav tau. Kuv tso nws qhov sib txawv vim tias kuv npaj yuav txuas ntxiv cov qij LED rau kuv lub tsheb.

Kauj ruam 5: Kev sib txuas

Kev sib txuas
Kev sib txuas

Yog tias koj xav ntsuas chav nyob sab nraum koj lub tsheb, txuas txhua yam raws li hauv qab no: B = Roj teeb +E = GroundL = Teeb (Qhov no yog qhov ua tau zoo. Txuas lwm lub teeb xaim rau hauv av.)*Cov kev sib txuas no yuav txawv rau cov tsheb sib txawv! *

Nov yog thawj qhov txheej txheem rau kuv chav flasher thiab hloov kho nrog qhov sib txawv resistor.

Kuv tau ntxiv ib feem qhov tseem ceeb uas nyob hauv kuv chav nyob rau qhov txheej txheem no.
