I Need Ur Help!

[Nismo_God]

Hi all,

Had a flat battery this morning. I tried to jump start and couldn't. I then tried to swap battery but think I may have done some damage as I saw a biggger spark then normal. Changed the battery back and now when I try to jump start I don't get anything.

This morning it was just a flat battery, ie central locking work, battery just couldn't turn the car over. Now it's got no power, no horn, no central locking etc.

Checked fuses, only electrics 10a is out. Could that be it?

Can anyone help?

Maybe you have blown the fusable link that hangs off the +ve terminal.

Is that the 10 cm link between battery terminal and fuse box?

Also changed the electrics fuse with no success

Is that the 10 cm link between battery terminal and fuse box?

umm bit late, but yes - that is the main "fuse" in the car.

did you get it sorted?

hang on... u guys mean to say that the bit of cable that runs from the positive battery pole into the fuse block is a fuse????

isnt it just a large gauge piece of cable that takes the positive from the battery to one side of the fuses and relays??

i have replaced this bit of cable twice when installing battery isolators and in no way did it look like a 'fuse'.

it looked to be exactly the same as the earth strap on the other side of the battery... just a piece of cable!!!

nope not sorted yet...

duncan are you refering to the boot or bonnet?

really just starting with this testing electrics....but if i put a multimeter on both sides of the fuse on either end of the fusable link with it connected....and it reads zero....does that mean its live or busted?

Problem resolved. The wire from the alternator to the dash failed. Can't believe that's all it was. Cars working like a dream. Thanks everyone!
