You cross the battery.
Disconnect the negative terminal of the battery Leave it disconnected for an hour. (The amount of time it takes to replace the battery). Reconnect the negative terminal of the battery. This works because a transient (voltage spike, noise) is generated when the terminal is reconnected. This is not necessary when the battery is replaced because the negative terminal is normally the last connected. However, when a car's battery dies in storage for example and is recharged with disconnecting the battery, the car might not start because the computer is not running.
Yes This Cable Is Connected To A Group Of Cables That Run To The Battery Positive Side, To Allow The Alternator To Charge The Battery.,Do Not Remove Or Install An Alternator Until You Remove The Ground Terminal From Your Battery.
check to see if battery is connected correctly. and correctly is positive cable to positive terminal
Most likely cable running from stud on top of alternator to battery terminal is corroded or broken.
Remove the Negative (black) battery terminal while the vehicle is running and if the vehicle dies then it's the alternator, if it stays running then it's the battery. Although this method isn't guaranteed it's usually accurate. DO NOT REMOVE THE POSITIVE terminal (red) from the battery while it's running. It could cause a spark and make the battery explode. Another way is to drive to Autozone or Advanced Auto and ask them to test it. They'll do it for free.
I have a 1995 Ford Explorer , and with the engine running a mechanic disconnected both battery cables and it kept running - I was surprised!
Most inverters will not be harmed by charging the battery [running the engine while the inverter is connected]. However, for safety [inverters are expensive] it is best that the Owner/User Manual be consulted to make sure that it is safe to charge the battery while the inverter is connected.
Power does not go to the battery, it comes from the battery, except when the car is running. At that time power does go to the battery from the alternator. Disconnect the + battery terminal.
with the car running disconnect the negative terminal from the battery if engine dies alternator is no good
Both posts are gray, positive has a red wire running to it, and a plus sign next to it.
You don't want to do that. If your cars check engine light is on, you need to get it examined by a mechanic. Also, if you disconnect any battery terminal, your engine will not start or power any electronics while it is running.
A battery gauge "moves up and down" while running because of fluctuations in the voltage output of the circuit which it is connected to. This may be because of equipment on the circuit.
