Jump start
« on: March 01, 2009, 09:48:52 AM »
read in the latio owners manual, qoute

Always connect positive + to positive + and negative - to body ground. NOT to the battery's negative.

This is something new to me as from all my previous jump start i always connect positive to positive and negative to negative. Maybe  i'm doing it wrong all this while.

not maybe, is confirmed

but most people will connect cables terminals to terminals and remove in the wrong sequence too (why? because they do not read the manuals .....)

Dear alghojo,

Connect one of the -ve terminal of yr jumper cable to ground, which could be any unpainted nuts  u see around the engine bay. Usually i clip it to the nuts of the shock absorber which is by the side of the engine bay. So that both cars are connected via a 'common' ground.

Hi bro Silver, is this only apply to latio or general for jump start? Believed the cab driver has helped me once with +ve to +ve and -ve to -ve on my previous drive (16.5yrs of corolla, 1.6M). Thanks to advise

applicable to all cars and not just applicable to Latios only

if you look carefully, there is  a plate attached to the body of the car - that's the ground that is supposed to be clamped to and definitely not to the -ve terminal of battery

this in nothing new but not practiced. The -ve to ground of car with bad battery is suppoed to prevent explosion of the bad battery from happening. Most people just clamp the -ve of bad battery. Other thing to take note is to connect the positive first and not the other way round. The last point to connect is the ground point of the car with the bad battery to complete the circuit.

There is another thing which is recommended, after the connection, run the car with the good battery for a few minutes to charged up the drained battery, then off the engine before having the car with the bad battery crank his engine, this is to prevent extra load on the alternator when the engine is on. Extra power pulled from the alternator during cranking could damaged it.

With a good jump start cable with low resistance, good battery is supposed to be able to start the other engine as if it's connected to it's circuit and thus it is not necessary to have the engine of the boosting car to be on.

BTW, not an electrical engineer so I might be wrong.

I think your last para is quite true coz there is once, i am jumpstarting my in law's car, cable connected, i haven got time to start my engine, my in law go crank his engine. For that moment i thought this will draw out all the battery and i wun be able to start mine. But i can.  ::)
