disconnecting the battery question ?

[r34_skyline]

sorry guys, i've got a really stupid question to ask. but please answer it without the laughter etc

when you're disconnecting the battery on the car, do u always disconnect the -ve first then the +ve ? when disconnecting the battery with the spanner(unbolting the polarities + and -), is there a possible chance of getting electricuted ?(say your spanner accidentally crosses both poles)

also, when u reconnect the battery, do u connect the +ve first then the -ve ?(other way around).

sorry about this guys, i''ve disconnected the battery before, but i just wanna make sure im doing it rite. i dont like the idea of being electricuted.

hiya

just changed the battery today in my other car lol

disconnect the '-ve' first and then the '+ve'

take battery out

put the '+ve' back on then the '-ve'

its a bit scary at first as it scares me stupid too

make sure the spanner doesnt touch both sides or u'll see alot of sparks and probably get electrocuted.. if you used a long socket like i did, theres a good chance of touching so just be careful =)

disconnect the -ve first, then the positive. when reconnecting put the +ve on first, then the -ve.

If the -ve is disconnected, and you touch the negative on the battery and positive together with a spanner, u'll prolly get electricuted, wont harm the car though. Never fear u wont die..lol.

Just dont connect -ve and +ve on the battery with a spanner when the leads are still connected to the battery.

thnx both of u .

ohh, 2 more question. should i use a rubber handle spanner ? or will the metal handle be ok aswell ?

"Just dont connect -ve and +ve on the battery with a spanner when the leads are still connected to the battery."

are u talkin about the jumper cables to start up a car ? lol sowwie, im abit out of it at this late hour.

when i take the batt out i just use a steel spanner, but when you do the postive side don't touch the body with the spanner when undoing it

actually if you do put the spanner on both terminals you will die

the amps from the battery are much stronger than the amps in your house

if you dont die, you will be on death row thats for sure. the number of cold cranking amps will fry you

I think the worst that can happen in this situation is maybe a burn from a very hot spanner. The current will take a path of least resistance ie. straight through the spanner. Very little will pass through your body. It is the equiviliant of taking off the +ve terminal while leaning against your can providing an earth, you should know that doing this will not give you a shock.

Now sticking your tounge across the starter motor terminals may cause a little grief.

What a lot of bulldust ,

The current in your battery is totaly different to the 240 volt A/C in the house mains . Whatever you do dont play with the house power , that can kill you .

The car battery is D/C ( direct current ) and it will not kill you at 12 volts , altough it has heaps of amps .

If you happen to touch the + and - with your body nothing will happen you wont even know it ( unless your hands are wet ).

If you put the spanner or a wire across the terminals then you will have sparks , it can burn you ( the wire will melt , spanner will get very hot , red hot ) .

The reason you disconnect the - ve first is if you touch the cars body with the spanner you dont get fireworks . when the - is disconnected the dody doesn't have - so if you touch the spanner on to it when you undoing the + nothing will happen .

Take care with it and you will be o.k.

bugger i had heaps of friends tell me the cca's from the battery will blow you away, much more than the amps from a 240volts outlet. sorry for the wrong info

Whatever you do dont touch the 240 volt A/C at home .

If you want just put your hand on the 2 poles of your car battery you will see nothing will happen .

The coil current will give you a good belt but it wont kill you , so dont hold the coil pack wire while the engine is running , thats not 12 volt .

as dan from dansdata below explains, "...nothing will happen"

HA HA Die from a car battery, heard it all.....

I accidently earthed the spanner before when I was tightening the +ve terminal up, lotsa sparks, no shock .

If you're dumb enough not to let a shower of sparks stop u from doing the wrong thoing you probably need a burn to wake you up

I shit myself, dropped my spanner into the bottomless engine bay and hit my head!

Remove your watch........

My friend had an expanding type watch band, rested it on one terminal as the spanner flicked across from the other onto the band.

Instant glowing red hot heater element.

Most painful trying to get it off his smoking wrist.

YOU WON'T DIE. I've done battery connect / disconnect numerous times. And I've accidentally created the spark show on many of those occassions.
