Battery Ground Cable Getting Hot
There is no engine light on battery light not on the car is running but the negative battery cable is smoking and hot.please help. A ground wire must be as large as the positive, or supply, wire to the battery.
My car has 118000 miles.
Battery ground cable getting hot. Hopefully you will never have to experience the joy of tracing a bad ground. Does anything get warm if the key is just in the on position? So when he cranked the starter, which can pull over an hundred amps, the negative connection from the starter had to go through the little wire that grounds the frame.
An easy experiment to safely make a wire hot is to use a transformer and connect a bare wire between the two output terminals. All you have to do is place the meter lead before and after the part that you want to test and then activate the circuit (while cranking the engine, or with engine running in your case). Turn on the transformer and watch the wire.
I have seen several issues with this one ground cable in many years, make and model general motors products. In this situation we have a failure of the main ground cable that runs from the battery to the engine block and frame. Jordan probably hooked his battery ground to the car or truck frame not the engine block.
Heavy #2 gauge cable should be used to connect the battery negative terminal to the engine block or starter mounting bolt. Bad ground on a 2004 jeep liberty if you have bad grounds and since some computer sensors and solenoids use the engine ground to supply electrons as half the circuit, you will just have issues. In some cases, it is referred to as the negative battery cable.
In terms of actual wiring, you want to use at least 14 gauge wire for the body ground (see our ground kit for more info). A negative ground cable from the battery to the engine should not get hot if it is the correct size, large enough gauge (dia.) and not too long. Next, take a voltmeter and check the dc voltage at the battery posts and then the post connectors with the car running and the positive post off the.
You can buy a lot of arc welding sets that will weld steel which run off a car battery. What kind of cables do you have going to the starter from the battery and from the battery to the engine block ?. When the cable becomes loose, you will start experiencing all types of electrical problems.
If an end is getting hot it has a loose or insufficient connection. The battery cable is probably getting hot because the amperage is passing through it directly, probably with little or no load (i.e. But if you find yourself in such a situation, these tips will help make the job go smoother—and get your ride back on ground level.
Would a bad solenoid cause battery cable to get real hot when trying to crank a lawnmower? Somewhere there is too much resistance in the cable. A starter for your car must cost $18, or real close to it.
Ground wire getting hot and melting. Report this by manage my life. Thanks for the input, i appreciate your suggestions!

The cable geting hot while the engine is runing usually means the alt to batt wire has a poor connection or some thing is the vehicle is shorting out ,the oem fuse links is there to protect the major electrical system parts from this shorting out and burning wires The positive side of the battery cable is directly connected to the starter motor so there is a possibility that the motor is shorted.see also if the wire is touching the ground. If you are testing a ground cable you can go from the battery post to the engine.
Check your ground from the battery also, clean them all. Another reason that your battery wire is getting overheated is its resistance. Nevertheless, intermittent ground connections can cause some really crazy side effects.
The wire comes all the way from the negative battery terminal and is connected to the chassis. Try starting for just a couple seconds. The alternator puts out current on the negative side into the engine block where it has to go up the negative cable to the battery.
May be a loose connection in the cable ends or possibly the cable has deteriorated along the cable somewhere. Battery ground is bolted to the block, and an 8g wire is bolted from the cable connector to the frame. The charger is also connected directly to the motor though the wire is somewhat smaller than the battery cable, it is best to check it also.
A vehicle that is getting poor performance from its battery can look to a number of causes, but a common cause is a corroded battery cable that is high in resistance. If not enough juice is getting to the starter or there is not enough is getting back through the ground, then this could be the problem. Change it anyway and you will know right away if it was rotten.
If this is the case, secure the cable firmly just like how you did when establishing the connection for the first time. Test it by using both jumper cables on the negative terminal and to the engine for a ground. A bad or loose cable connection can cause it to get hot.
Check the two wires from the battery to the frame, the ground wire, and the starter, the hot wire. It will get warm and may get hot, depending on the thickness of the wire. I did clean all connections before reinstalling the new wires, so, can i rule that out?
Not big enough to ground a starter. Any appreciable voltage (> 0.5v) means you have a bad cable or connection somewhere in the ground path. You know how hot a 40w lightbulb gets.
My negative battery cable is smoking and is hot on the battery terminal when the car is running.i just put a new battery in last week but noticed a burning smell from the engine today. Will spin over but not crank and cable gets real hot. Sometimes the cable still looks good but inside the copper will.
Clean the other end of the cable and the bolt where it grounds. So you might get by with cleaning the battery & wire really well then drilling a new hole or filing to old one enough to get purchase with a nut bolt and some washers. A braided copper ground strap is best attaching the engine to the frame.
Ensure that the connection is intact and has not come undone or become loose. A ground could be good but the supply of power could be hindered. If the ground wire is loose, then the alternator won't deliver its full power to the battery, particularly at idle.
Depending on where it gets hot should indicate where the problem is. Check that negative battery cable and if the rubber is cracked all over, it is gone. The ground is a major part of the battery's charging system, so assuming that you're getting proper voltage output from the alternator wire, and the battery isn't hashed, then you may be looking at a bad ground wire.
Negative side of battery cables getting very hot i would look for a short to ground in the starter or starter solenoid, something that could transfer a large amount of current when the starter is powered up. If that doesn't help you may have a bad solenoid.
