baliktad pagka-series ng battery

[elo]

baliktad pagka series ng battery now ayaw na mag start fuel injected ang engine possible ba computer box nasira it cranks but wont start pls help

You mean the polarity was reversed? Oooohh.. you're likely screwed.

Check the fuses that has anything to do with the ignition and fuel pump.

Worst case, yes, you may have a dead ECM on your hands.

I don't think the fuses would be affected.

I really do think the engine ECU would be fried. Maybe the electronic ignition system as well (if the car is equipped with a separate unit from the ECU).

thats the last thing you want to happen but it happened.

best case scenario is you have a main fusible link blown .

worst is yeah a fried ecm/pcm

Malaki ang posibilidad na nasira ang electronic components ng sasakyan...

Normally, may mga IC regulators sila to bring down the DCV from 12V to 5V/3V where most electronic parts operate. Sana regulators lang,- pero ganunpaman,- they're mounted on the PCB...

Some electronics with electrolytic capacitors at the input would appear "shorted" when the polarity is reversed. When that happens, there's still a possibility that the fuse was fast enough break the circuit before any permanent damage was done.

Although slim, it's still a viable possibility.

Guys correct me if I'm wrong. Diba ang connection is (+) of dead battery to (+) of good battery and (-) of good battery to (-) of dead battery. If I'm correct mali kasi ang term na ginagamit, dapat battery paralleling at hindi series baka kaya may mga nagkakamali. Ang series kasi is (+) to (-) connection.

^^ yun kasi usually term kung ginagamitan ng jumper cable yung dead batt. pero electrically speaking, tama yung sinabi mo.

i hate to say this but i think majority of your electrical might be fried. hugutin na yung ECU and smell if its burnt. tapos pacheck na lang sa electrician.

at first i checked the fusible links and fuses all of them are good , got my battery today after recharging it tried starting it and it started thank you god

Definitely you're right. Noon ko pa nga kinokontra yung term na ginagamit dito sa atin sa Pinas eh, misleading kasi. When we say series connection...the resultant Emf (voltage or electro motive force) will be the sum of the individual Emf of the batteries... Battery 1= 12volts, Batt 2= 12volts. So, VT= V1 + V2, ang resulta Total Emf = 24volts. Eh sabog lahat ng electrical components ng sasakyan kapag series connection ang ginamit (for 12VDC system only). It should be called parallel, where as VT=V1=V2....so on and so forth. Sa parallel connection, the total emf is equal to the individual emf of the batteries, only the Total Current (I or amperes) is the sum of the individual current of the batteries, kaya lumalakas yung pwersa (initial torque) para i-crank yung cranking motor (starter) kapag ipinarallel yung dead battery sa good battery.

SERIES CONN PARALLEL CONN
VT= V1 + V2 + V3.... VT= V1 = V2 =V3.....
IT = I1 =I2 = I3.... IT = I1 + I2 + I3....

Kaya lang hindi na natin mababago yung nakasanayan ng mga pinoy eh kahit mali, yun ang natututunan eh. Minsan sinubukan ko gamitin yung term na parallel, tinawanan lang ako ng auto electrician, hindi nya kasi alam eh. But in fairness, alam nya yung gingawa nya, bad technically speaking, mali yung mga terms na ginagamit, hindi papasa sa industrial standards. Eh alangan makipagtalo pa ko at sabihin ko mechatronics engr ako, kaya hinayaan ko na lang. But if and when I talk to youngsters, itinatama ko para hindi sila ma mislead, kahit naman sa HS eh itinuturo yun.

To sum up, if the connection was mistakenly reversed, I am afraid the Electronic Control Module (ECM) is already busted, UNLESS otherwise equipped with reverse current protector yung system mo, pero very rare ginagamit sa atuomotive yun, most often sa industrial applications lang ng engine nilalagay yun, especially sa planta. the best thing you should do eh ipacheck mo sa electrician na marunong magdiagnose ng ECM, wag sa ordinary electrician who only knows the old technology. ECM is a hightech process control device, it functions like a computer. So I suggest ipacheck mo agad ng hindi na lumaki ang damage if you try to start over and over with out giving remedy to the trouble.
