Jumper cable amp rating

[Retz]

Jumper cable is a must for auto tranny vehicle.

nahilo na ako sa thread. yun negative ba dapat i ground pa or hinde...? o flashlight na usapan?

sariling gawa na jumper cable

pang start ng 24V trucks and heavy machines




di ko na kailangan problemahin ang amp rating amp rating na yan

that's welding cable

more than enough for any starter we got here

i have a black and decker jumpstarter kit (since A/T oto ko). instruction
nya is + to + (Jumpstarter kit to car batt)
then - to car chassis/solid body part.
reverse pag tapos na.

Boost Ampere: 375 instantaneous cranking amps (according to the manual).

Parang gets ko na kung bakit not recommended ang negative to negative terminal. May napanood ako sa Discovery Turbo (The Garage). Pekeng M3 ginagawa nila and namatayan ng battery sa shop kaya ni-charge muna. After a few minutes charging nagstart na so tinanggal na ng mekaniko ang clips ng charger. Biglang BOOM! Yun pala di nya na-unplug muna ang charger bago tinanggal ang clamps. Nagspark pagtanggal and nag-ignite ang gases sa loob ng batt. Takbo agad sa CR ang mekaniko para maligo.

So if nasa block or body ang ground connection mo pagtanggal less chances mag-ignite dahil malayo sa battery. Once natanggal na yun wala nang circuit so safe na tanggalin ang iba.

ganto na lang, kung ayaw neg to neg, edi lagay sa body neg.

edit: sa jumper cables, Ewan ko ba kung bakit kailangan alalahanin amp rating, basta gumagana ok na yan. kahit kasing kapal pa ng braso, 12v to 12v or 24v to 24v, yan pa rin ang dadaloy na voltage.

when you're charging a battery using a charger the battery gets warm and the battery acid will bubble and you'll smell acid vapor

but that doesnt happen immediately after you connect the charger. it takes several minutes before that happens

connecting a good battery to a dead battery is like connecting a battery charger to the dead battery. it's not gonna make the dead battery charge up agad and release vapor

so it's unlikely a spark will cause the dead battery to explode

overly cautious lang ang mga Kano kasi ayaw nila mademanda

wala naman pumipilit sa inyo mag neg terminal to neg terminal

use body ground all you want

like cathy did. she followed step by step instructions pero di niya na-start car niya. may nagsabi tuloy stuck-up na makina niya

pero napaandar niya noong pinalitan niya ng battery

so what went wrong?

suspetcha ko body ground. mali location pagkalagay ng cathy. kung nilagay niya sa neg terminal umandar sana yan

in those few seconds kukulo ba ang battery acid at magrelease ng vapor? i doubt it

Anlake! Yung DIY ko from inverter welder kaya gauge 3 lang, pero palagay ko kaya din magstart ng 24V neto. Pwede din double purpose, tow cable..haha

Dapat well ventilated. Hydrogen buildup nangyari.

Dapat consider wire gauge, ang analogy ng wire is parang tubo ng tubig. The larger, the more current could pass. Kung malaki ang amp draw ng starter at solenoid, iinit lang ang wire (electron congestion).

As a general rule based fron nabasa ko - gauge 6 for small cars, extending the length increases the resistance so u have to increase the gauge, the bigger/shorter the better.

umabot pa sa transmission and pulley, labo.
