First to do it, find the year of your GMC in the car's owners manual or on a recent car insurance slip. Go to your local auto repair store. Give the store clerk the year, make and model of your car and tell them you need to purchase a new positive and negative battery cable for your vehicle.

a.- Take the keys out of your ignition and reach down under your dashboard on the driver's side and pop the car hood.
b.- Find the battery under the hood.
c.- Remove the red positive cable and black negative cable connectors from the battery terminals with a pliers or wrench.
d.- Grab the disconnected black cable and run your hand along it until you get to its other end. The black negative cable is connected to the frame of your car with a single nut. Use the proper size wrench to unscrew the nut. Put the nut in a safe spot and pull the black negative battery cable out from under your hood.
e.- Grab the disconnected red cable and run your hand along it until you get to its other end. The red positive cable is connected to the vehicles starter with a single nut. Use the proper size wrench to unscrew the nut. Put the nut in a safe spot and pull the red positive battery cable out from under your hood.
f.- Take the new red positive battery cable out of the package. Position the flat eyelet end of the new red positive cable onto the cars starters bolt, where the old cable used to be attached, and re-screw the nut into place.
g.- Take the new black negative battery cable out of the package. Position the flat eyelet end of the new black negative cable over the cars grounding frame bolt, where the old cable used to be attached. Re-screw the nut into place.
h.- Reattach the new red positive battery cable to the positive terminal of the battery and tighten it with a pliers or wrench. Reattach the new black negative battery cable to the negative terminal of the battery and tighten it with a pliers or wrench. Shut the hood.

I hope help with this; if have other question just send us comments.

Need to know where the positive wires that connect to the battery of a '95 Toyota previa connect.


The black wire will be connected to the body or engine of the van and the red or positive wire is connected to your starter motor.
You can also use a 12 volt battery light to check the negative or positive wires.
You take the 12 volt battery light and place the negative black wire clip to an earth on the vehicle, then when you touch the tip of the 12 volt battery light onto a positive wire the light will light up.
Then you will know which wires are negative or positive sometimes the key has to be on for some wires to work.

The red lead wire on the back of the alternator has pulled away from somewhere and I need to know where it attaches to. This is on a 1997 Chevy Cavalier 2.4 engine. When I took the bolt off of the red lead...

That heavy gauge red wire (called a B+ wire) runs from the positive side of the battery directly to the back of the alternator. On yours, if it goes to the starter, the starter main battery terminal would essentially do the same thing. (both connections are always hot and always come directly from the battery). If you meant that it became disconnected when you said "pulled away", you need to find the wire it disconnected from and re-connect it. If it just came out of a loop that was securing it, you don't necessarily need to find the loop but can secure it with a tie wrap, making sure it stays away from the manifold.
You could actually make a new wire and connect it between the battery (+) terminal and the alternator, using the same gauge wire, but I'd be concerned that the loose end coming from the starter could possibly touch something and cause a direct short. At the least, you should find the loose end and cap it off. The battery cannot charge with the wire disconnected.
Anything I've just written that you don't understand, just ask and I'll clarify it for you.

Starter motor engages when motor is running

Check your Solenoid Most likely bad and needs replaced, but it could be key switch not returning, or return spring on the starter bedix and you may need to replace your starter. It would be best to just replace your starter... Usually no way around it everything wears out eventually and this is a common problem when Solenoid is going bad, just had to replace it this summer on Our Ford Truck it was doing the same thing..

Hope that this advice is helpful and gives you a place to start Please or/and leave a testimonial for my advice and if I can further assist let me know.

I have a 98 saturn sw. Replaced the alternator, there's a wire, thick looks like it goes to the starter? Didn't take this wire off, don't know where it goes. possibly called the B wire. Alternator reading...

There is a heavy red wire that connects to the only terminal on the back of the alternator. The starter should have a smaller purple wire connected to the starter solenoid. A red (positive) battery cable connects to the top terminal of the starter solenoid. There also may be smaller red wires connected to the solenoid at the same connection where the heavy red battery cable connects. Hope this helps

What wire go where on 1980 F 150 4.9 starter

I have provided an image that will assist you and it will connect like so;

1. Connection 1 should have the Pos. (+) battery cable and all of the wires with the large eyelet connectors from the wiring harness connected to it, except for the large cable that runs down to the starter.

2. Connection 2 should only have the large cable going down to the starter connected to it, and there should be no other wire connected there.

3. Connection 3 is the "S" terminal on the starter solenoid, and it is the wire with the small push on connector that is hot only when the key is in the "start" position, usually it is a red wire with a blue stripe, but that is not always the case.

4. Connection 4 is the "I" connection on the starter solenoid and it feeds current back into the ignition, and it is not used on a lot of vehicles after 1981, but if your vehicle has it it will be a small push on connector that will not have any power from it at all, and it will usually be a black wire with a white stripe, but that is not always so.

My battery keeps going dead. I have had everything checked and no one can find the problem. someone suggested it might be the abs. I don't know what to do next.

Did someone run a volt meter on the battery while the engine is running? To see if the altenator is good you must connect the voltmeters positive probe to the negative terminal of the battery and the negative probe of the volt meter to the positive terminal of the bvattery. Set the volt meter to the DC mode and see if you get a reading. If so the altenator has a bad diode keepthe battery to reeceive a charge. The diode keep the current running one direction you see. If you connect the probes the way the should be , red on red and blac k on black you will receive the same reading. When reversed you should get a zero reading with a good working altenator

Battery works, alternator and starter work, but car dies after running. won't turn over.

Does the bvattery lamp work when you turn the key on?? if so does it extinguish when the engine is running. If so then battery or cable / connections are fautly. If not then alterantor / wiring is suspect.
