1 Answer I hook up the power to instaall into anotheer car

Are you asking how to hook up some jumper cables? If so, connect the two leads on the car you're jumping to the positive and negative terminals on the battery. Then connect the leads on the other end of the cables to the positive terminal (same cable as on the car to be jumped) on your battery and the other lead to a good "ground" (a manifold bolt, chassis bolt or - least desirable - the negative terminal of your battery). Be careful not to touch together or cross/switch the leads on either end of the cables once one end has been connected.
If that isn't what you're asking about, post back and we'll go from there.

Hi, I have a 2008 Pontiac G5 and I accidentally kept the lights on all day. Since I only have a positive (red) connection, I ground the negative connection to metal as well as the other car negative...

sounds like you are on the right track. Hook the jumper cables up to the dead car first. The red cable should go to the jumper terminal as you mentioned and a good place to hook up the black cable is the bolts on the strut tower.

then with the other car running hook up the red lead to the cars positive battery cable and then the negative to a good ground. Let the two cars sit for about 5 to ten minutes to give the dead battery a chance to charge.

Once the dead car is started let it idle with the lights turned off for at least 45 minute to an hour or drive it for the same amount of time with the light on (I assume you will be driving in the dark) or if its day time drive it for 30 to 40 minutes with the lights off. This should be enough time for the alternator to charge the dead battery.

Have a delcotron alternator ,what to know where no.1 terminal and no.2terminal wire goes it is on my 1946 cj2a jeep my amp hand does not show a charge had alternator checked out and is ok

  • Use a wrench to remove the negative and positive battery cables: They are clearly labeled "+" and "-." Always remove the negative cable first, as this isolates the power to the metal parts of your car. Tuck the cables away from the battery as you don't want them to accidentally touch a battery terminal when you're wiring your alternator.

  • 3

    Locate the alternator terminals. There are two: one marked "live," "pos" or "+" and the other marked "neg," "field" or "-."

  • 4

    Locate the two cables. The positive (red) cable goes to your battery via a wire loom or harness. The negative (black) cable attaches to a metal part of your car.

  • 5

    Check how the cables attach to the alternator terminals. Some connect using eyelets that hook over the terminal and tighten with a bolt; others connect by inserting the wire under the terminal and tightening a bolt.

  • 6

    Loosen the two bolts using a suitable-sized wrench or, if the cables connect using eyelets, remove the bolts.

  • 7

    Insert the exposed end of the negative (black) cable under the loosened bolt on the negative terminal of the alternator, then tighten the bolt. If the cable has an eyelet, hook it over the terminal and screw the bolt back in place and tighten using a wrench.

  • 8

    Insert the exposed end of the positive (red) cable under the loosened bolt on the positive terminal of the alternator, then tighten the bolt. If the cable has an eyelet, hook it over the terminal and screw the bolt back in place and tighten using a wrench.

  • 9

    Replace the positive battery cable on the positive battery terminal using a wrench. Replace the negative battery cable on the negative battery terminal.

    I am concerned that if I change the main battery in my 1999 9-5 that it will require re-programming of the security system. Can you tell me if this is true?

    OK, it is possible to change the battery and keep voltage supplied but you need a third battery and jumper cables. There is always the possibility of shorting connections unless you are quite careful. You hook up the jumper cables to the battery terminal clamps and the third battery and make sure you don't break the connections as you put the new battery in. It is also possible to hook up the third battery to another grounding point and an alternative positive terminal somewhere in the engine compartment. It's just a matter of finding the connections that you can hook up to. This is the surer method. Saab were always pretty easy to find a positive terminal to hook up to. Some models even had an alternative boosting point under the bonnet so that you did not have to make sparks around the battery. Any help?

    I'm trying to install a new battery in my 1984 Nissan Sentra. When I hook up the terminals, the wiring starts to smoke leading me to believe that the hook up is backwards. What is the correct hook up for...

    Hi and welcome to FixYa, I am Kelly (Electrician since late 1960's)

    Ground goes to the - pole. Hooking it up backwards can damage your alternator, wiring harnesses and fuse links. (Fuse link damage is a nightmare to sort out!) What you do by hooking up a battery backwards is turn your vehicle wiring harness into a giant heating element. (<-Very bad!) If you just changed the battery and then you hooked up the cables with the smoking cable result you certainly did connect the cables backwards. The ground cable... will connect to chassis and in most cases the engine body / transmission somewhere.
    The positive cable will eventually connect to the starter. Follow the ground lead from the battery to the chassis or engine body connection. (metal to metal contact) Once your sure that is the ground cable; connect it to the - post of the battery AFTER connecting the positive post terminal.
    If you have a newer audio system you will have lost your radio codes. We can not provide the codes for anti-theft reasons. Activation Codes must be from the car dealer or audio system retailer.
    Thanks for choosing FixYa,

    Should the battery charger be connected directly

    Typically - Yes.
    Some GM cars (and Mercedes) have the battery concealed and it offers a remote positive terminal for checking and charging.
    You should connect to the positive terminal whenever possible. The negative side of the charger can be connected to any metal on the vehicle. Ground is ground - all over.

    Transmission wont upshift untill 4500 rpms

    Some cars have a similar problem with the electronics of the instrument panels. If you disconnected the battery for, say service or new battery replacement, the power that keeps the electronics in the instrument panels is instantly removed, and this means that during the time when the battery is reconnected (or when a new battery is installed), the instrument may have lost some of it's memory, normally the trip meter is the first to loose it's stored information (but not the odometer, the odometer has an internal battery back-up. Depending on the car, early model or latest model, you may loose more or less of the settings that keeps the car in order). Perhaps your auto transmission (you called it gear box, I believe you are referring to an auto transmission) may have devices that upshift or downshift the gears via an electronic controller. This may have been disturbed when you disconnected the battery and may have lost some of the factory setting. So, resetting the system to original factory standards is important so that everything works as it should. And also, as I said, if your car is a newer model, it is wiser to first connect a fully charged battery in a 'jump-start' fashion before disconnecting the battery that is already in the car. To connect the new battery, use a set of Jump-leads, one end connected to (+) and (-) of a separate battery, and the other end connected to the battery in the car, not directly on the battery terminals but to each exposed positive and negative battery clamps that are connected to the car battery. Then, assuring the power is definitely applied to the clamps of the car battery cables, you can remove or disconnect the car battery clamps without having any risk of power loss to the circuitry. This way, the power is still applied to the electronic systems while the old battery is removed, so the system will not be deprieved of power. It's a bit like your brains, remove the oxygen and part or all of it dies, but not always if you immediately revive it in time, however, there is always a bit of brain damage there, isn't it? The same goes when you remove power from critical electronic components that keep the 'brain' of the car alive. Although you may have made a mistake in disconnecting the battery, you can still fix it by contacting your trusty local new car salesyard mechanic. This, I am pretty sure is the only solution to your problem.

    1999 Subaru legacy will not start

    Check your terminal connections, if they are loose they will need to be inspected for breaks. If they are broken you will need to replace the connection. Make sure they are clean and free of corrosion.

    Other possible Problems
    If the car wont turn over your starter could be bad.
    If it turns over but wont start it could be any number of these problems.
    Coil Pack
    Plug Wires
    Spark Plugs
    EBX (Engine Brain Box)
    CBX (Chassis Brain Box)
    Crank Sensor
    Fuel Pump
    Fuel Rail
    Fuel Injector

    Good luck
