Why does my car battery not start when I plug it in?
Connect the red lead to the battery positive, and the black lead to the opposite end of the cable going to the starter and iirc you should not see anything larger than about 0.7 volts. Here’s a good video on testing a battery with a multimeter. It could also be a starter problem, which you can read about here.

What happens when the starter doesn’t work?
Basically, with a fully charged battery, and with the key held in the “start” position, the starter is either getting power or it isn’t. With the key in the “start” position, if the starter motor is getting power but the starter doesn’t work, then the starter is condemned and replaced.
What should I do if my battery has no starting current?
If you have no starting current, check the “open circuit” (ground cable removed) from the battery and the voltage checked at the battery’s terminals. It will almost always be normal. Reconnect the ground cable and re-check the voltage.

What causes a car battery to not start?
Most auto parts stores will test a battery for free to see if it has enough voltage and cold-cranking amps to start the engine. If the battery passes the test, then it isn’t being sufficiently recharged. That could be caused by corrosion on the battery terminals, or a loose or faulty cable.
What does it mean when your car won’t start?
My truck wont start, no click, new battery. Hi There, It sounds like you may have a faulty connection or potentially a faulty starter relay not allowing power to be sent to the starter solenoid. The starter relay directs power from the battery to the starter solenoid which… Hello.
What does it mean when your car wont start?
It could also be that the battery and alternator are ok, but that you could have what is called voltage drop.

What should I do if my battery won’t start?
If you run into this type of problem a cheap voltmeter can become your best friend.

Reconnect the ground cable and re-check the voltage.
What does it mean if your spark plugs are not working?
If the spark plugs are not working correctly, you might feel your car cranking but cannot turn over the engine or start the vehicle. If you hear cranking, but your car won’t turn over but has power, this could be signaled by loud cranking.
What should the voltage be when a car won’t start?
If you have a meter handy, check the voltage. Should be over 12v. If unsure of state of charge, have someone crank the engine with your meter still on the battery terminals. If the voltage drops sharply when the starter is energized, it’s the batt. Hmm, I have emergency road service as part of my insurance (though I don’t have AAA).
Why does my car not start without a battery charger?
Without the battery charger hooked up, using just the key cranking the starter or at least trying to crank the starter does either battery cable smoke or get too hot to the touch? helpful? helpful?

Can a bad car battery be a bad battery?

Why is my starter drawing too much current?
This puts a big load on the battery. The problem you describe is due to either a battery with a low charge, faulty wiring to the starter or, the starter motor itself is bad. Have the motor checked to see if it is drawing too much current from the battery. Please allow me to echo what mcparadise stated.
Can a starter motor be turned on without a battery?
Trust me–most batteries that are incapable of turning the starter motor will allow lights, horn, etc to function. As was said, if this is the original battery, it is OVERDUE for replacement. In fact, by using the original battery for too long, it is possible to damage your expensive alternator.
Why is my car starter not working properly?
In order for the starter motor to work like it is supposed to it requires more current from the battery than any other electrical device on the car. This puts a big load on the battery.

Verified ignition in the locked position and left keys out of ignition. Again, when I touched the negative battery cable to the negative terminal on the battery, the starter engaged and tried to start the motor. Could the battery be bad?
Can you start a car while the battery is charged?
Best not try it. A battery charger delivers a few amperes at most. A properly charged battery delivers enough to turn over a starter motor or to melt a steel bar put between the poles. (Hint: do not drop steel tools on both the + and – poles. If you are curious google on it instead).
Why does my Honda ATV start all by itself?
But, when attempting to put a brand new battery in today, as soon as I try to attach the 2nd battery cable, the machine tries to start all by itself, just with touching the battery cable to the battery terminal.
