battery disconnecting

well when i go to disonnect my battery i get a sprak which obv means something is connected what could it possibly be? all lights and dash board stuff is switched off although i do have a swith immobiliser hidden under dash could it be that?

and also i hate batterys !! it actually really hurt should i wear rubber gloves

sorry to sound stupid but i had am massive shock last year and had to go to hospial so i am a bit wary!"""!!!!

Not necessarily it could be a coil collapsing or a capacitor discharging.
The only way to be sure is measure the current, then start disconnecting stuff.
I would strart with the alternator if you have
one as the excitor coil could be energized.
(Be careful as you can blow you meter up very easley with a car bat)

how big is the spark? are we talking flyzapper or national grid

yu are always disconnecting the earth first?

Aye. Earth, off first, on last.

you are putting the terminals on the right way roond arn't you?

now earth being the red one on my car(-) stays on all the time as it is in storage so has to be disconnected so should that come off first?? and then the black one that gives me a sprak and shock well its fairly big its like you touch it against the body or something??

well it starts so i pressume they are on the right way red to (-) and black to (+) as mines opposite for some reason!

More than likely will be positive earth if it's an owld un.

where go your red and black leads head off to? which one is attached to youe chassis?

If you have a ford V6 it would follow that you have a negitive earth system. No standard ford v6's had posy earth. Do you have an alternator or a dynamo charging system.??

early capri V6's had pos earth on the essex engine
