My mate's Sierra has a flat battery (been sitting like that for weeks).

I'm gonna try and charge it with my 'inteligent' charger.

 

If that doesn't work, is it OK to jump start it from my 300?

Should I have my engine on or off when I try?

 

Cheers lads!

OK to jump it, leave your engine running (if his is dead it might stop yours starting by draining batt!!!)

Connect leads on car as pos to pos but connect neg to earth (not neg to neg)

What would be the best place to earth this then?

Do you earth on the Zed or the other car?

 

I'm slightly thicker than treacle but not as thin as missisipi mud :smw:

earth to anything on the engine as that will be connected to the body (all cars nowadays are negative earth...ie....the - (black) terminal is essentially connected to the body..)

So connect your earth to the other cars earth...anything will do, as long as it is not insulated from earth...try clipping it to the suspension turret. Its a matter of finding somewhere convenient....anywhere will do,

 

The reason for this is because of the battery which gives of flamable gas....dont want one of them to go bang....thats why when u charge em they always advise no smokey and ventilated area...

Always connect 1 lead at a time starting with positive (if u do the other 1 first then when you connect the pos there will be a bit of a spark on the battery)

Never seen 1 go bang but the manufacturers seem to be worried about it hence the warnings...
