Jumper cable amp rating

Sirs, ask ko lang. Critical ba yung amp rating ng mga battery booster cables? Sa 2.0Li na engine ano dapat rating?

TIA.

In my experience, YES. Lower AMP rated cables simply cannot carry enough current to crank-over the stalled car and just end up getting hot and may even melt through their insulation. But it does not really matter if the car is a 1.3 or 2.0L ....

Thanks alot Sir.

Most commercial jumper cables are 4 American wire gauge size do automotive use and will suffice for a 1.3 liter gas engine

So what's the ideal AMP rating to buy at the least?

Maybe 400 or 500 amp cables....

Also aside from the wires, check the quality of the clamps.

^Thanks.

I had one of those cheap 250 or 300amp ones before. It broke (the clamp in particular) after we tried jumpstarting my neighbor's Beetle. :D

On connecting jumpers:
1. Red (+) on the drained battery
2. Red (+) on the good battery
3. Black (-) on the good battery
4. Black (-) on a chassis/ground point on the car with the drained battery.

This is correct right?

Do note that the larger the engine displacement, the larger the cranking current. Also, Diesel engines, due to the nature of their design (higher compression ratio), will also have higher cranking current requirements compared to a similar-displacement gasoline engine.

Yup, and 4 to 1 when you remove the jumper cables.....

BTW, where is Master LSB?...

There is more to the story than jumper cables.... :naughty2:
