Using a VE to jump start

[Goggles]

tried to use my SSV to jump start a work colleague's car this afternoon using the under bonnet battery connection on my car, however it didn't work.

here's what I did:

1. Kept my car running
2. connected the jumper leads to the battery of the other car.
3. connected the other end of the red (positive lead) to the terminal under the bonnet of my car
4. connected the other end of the black (negative lead) to a metal bit of my car (part of the the front fender).
5. tried to start the other car, with no luck.

what did I do wrong?

Also, how do I remove the cover on the positive terminal of the battery in my boot?

no it wasn't

If you connected everything up as advised in the owners manual, there is no reason it wouldn't work. The fact that it didn't work either way suggests a common issue somewhere.
Make sure you use the correct jumper points as listed in the owners manual. People have been blowing things up by jumping off various parts of the engine bay, particularly clamping negative near the relay housing on the drivers side.

thanks - I will have to drag out the manual and have a read.

I was under the impression that the "-ve to ground" rule was for the FLAT car.

So:

Flat car
+ve lead to +ve terminal
-ve lead to a ground point

Good car
+ve lead to +ve terminal
-ve lead to -ve terminal

Don't quote me on this, but I'm pretty sure that's what my manual (VX) says.

VE = battery in boot

I've jump started my mates car using my VE SS ute... You just have to find the metal earthing piece and then you connect the other to the +... I'll take a picture for you tomorrow and send it through to you :)

the metal bit u say the actual earth point like it says in the manual to jump start the car?? or just any piece of metal u found at the fender?

positive terminal cover simply pulls off

I'm not sure what you mean by this... If the -ve terminal isn't connected to a ground then that's probably the problem... The -ve can be put on the battery or any good quality ground and it'll be fine :)

Note:
Good quality ground = bare metal. Not painted or coated metal :)

just any piece of metal found at the fender - not being familar with the VE underbonnet area, I didn't realise until reading the replies in this thread, that there is a specific negative terminal under the bonnet.

For the last 30 years of my driving and jump starting cars it was:-

Pos to pos and neg (on the good car) to an earth on the bad car. Havent tried it on a VE, but has worked on dozens of cars over the years. Are Ve's different? Is the above what you did?

probably not grounded right , couldn't go battery to battery ??

With modern computer cars you should also turn your lights on , on both cars ,
to absorb any spike or surge .

[swingtan]

As far as I know, all VE's are the same and look like this.....

Note the plated metal contact to the lower right of the pic, this is the Earth point.

Would like to know how having lights on absorbs spikes, and what do these spikes consist of high voltage, high frequency, high current or a combination.

Most problems with electronics when jumpstarting is reverse polarity no amount of lights on will help.

Most problems with jump starting is actually a voltage spike, commonly when first connecting and/or disconnecting the leads to the dead car....
Using surge protected jumper cables will minimise the risk of a surge/spike.
The theory of having the lights on is based on the assumption that the load of the headlights will absorb the spike.

very funny and also true :rofl:

can you use any old set of jumpers to jump start from modern cars?

for some reason ive had a thought in the back of my mind you need to use a certain/newer type of jumper cable to make sure you dont blow anything up

It's not compulsary to use surge protected leads. Just follow the manufacturer recommended way to connect and disconnect them, and there is very little chance of any issues.
