please help
i'm tring to change my fused HEADLIGHT and how do i remove negitive battery termial?

 

You won't need to with the headlight but to play it safe...

try a 10mm socket.

 

loosen up the nut with a set of pliers and it'll slide right off

 

Hehehe ... ever worked with a 10mm on the positive battery terminal and accidentally contacting the tie-down bracket?

 

Unfortunately... yes... in my early years... Early attempts to arc-weld...

That's why you take off the ground first.

 

i think in his situation, the tie-down acts as its own ground...

 

Actually if the ground terminal is removed, the tie down is no longer a ground cuz the circuit is broken... but ME NO EXPERT

 

Why anyone would ever tell you to remove ground from battery when changing headlights is totally beyond me. Maybe you should remove the ground when you are wash your car too.

Changing light bulbs:

1. Make sure you are wearing rubber boots.
2. Wear current resistant socks, underwear and gloves
3. Purchase all new insulated tools.
4. Park car on dry level ground
5. Pull parking break and pop hood.
6. Carefully exit the car and move to the front. Being careful not to trip on a rock or slip on the ice or anything. You wouldn't want to get hurt.
7. With a rag, lift hood above the Nissan emblem and locate secondary hood latch.
8. With other hand, holding rag, lift up on the latch to release the hood.
9. Place long enough 2x4 to hold the hood up being careful not to get any splinters in your hands.
10.Are you wearing the afore mentioned protective clothing?
11.With your insulated socket wrench and 10mm socket, loosen bolt on neg battery cable on terminal.
12.Pull up so the ring connector comes off the terminal.
13.Locate bulb socket.
14.Remove wiring harness to bulb.
15.Be careful not to contort your hands so one is on the positive terminal, negative terminal while holding the harness and with no shoes or socks on standing in water.
16.Since you can't feel very well with the gloves on, it is likely you will break something plastic and need to go to a shop to get it fixed.
17.Sorry, it will probably cost around $100 this way.

I remove my ground every time I fill up.

 

if the ground terminal is removed, you can still use the body/metal part of the car as ground.

if the tie down is connected to the body of the car, then electricity will pass through.

 

If I paid attention during physics/chemistry... and IIRC, You need a complete circuit to flow electrons. Since the battery's (-) has been disconnected (from the body of the car, which includes the tie down), there's no circuit.

Try this...

disconnect the battery's ground then hook up a test light to the tie down and the positive of the battery...

If you're right, the test light will light up.

 

sure sure... you're a pretty smart guy for not paying attention in class hahaa... when I get my supercharger for the turbo then you will be who I ask to help me install it!!

 

If the ground terminal is removed from the battery, you lose your ground connection (body is no longer grounded to the battery).

Tie-down = metal.
Battery tray bracket which tie-down attaches to = metal

Battery negative cable is just a short lil thing that bolts to the vehicle frame, effectively grounding all metal parts that are in contact.

So removing the battery negative cable wil break the circuit ... I say, just remove the battery all the way. In case there is some residual charge left in the battery tray, remove the tray too. Oh wait, the tray is connected to the frame ... anyone got a circular saw, got to remove that too
(sorry, got carried away ... it's 7am and at work now, tired)

 

Twice blown? I'm jealous!

Whatcha bring me back from Taiwan? haha... j/k!

 

I had a funny dream

watcha want from Taiwan!? I'm working on getting a few VI covers back oveer here haha

there is an STi Supercharger kit over there
