Battery tests 'unstable' when car is running, but tests 'okay' when not? This means that the root of the problem is occurring when the engine is running ... check the alternator or voltage regulator ... either one may need to be replaced or repaired.
The glove box light is so low in current draw that it would take weeks upon weeks to totally drain the battery. On most cars (for certain my '04 Jetta) built in the past 5 years, the glove box light only works when the engine is running.
Center terminal is connected to the positive from the battery. Outside is connected to ground (-).
Note: When interconnecting A200 batteries (cells), they must be identical in voltage and amp rating! Batteries may be connected in series. The positive terminal of the first battery is connected to the negative terminal of the second battery; the positive terminal of the second is connected to the negative of the third, and so on. The voltage of the assembled battery is the sum of the individual batteries. The batteries are connected: + to - to + to - to + to -, etc. The capacity of the battery is unchanged. Batteries may also be connected in parallel. The positive terminal of the first battery is connected to the positive terminal of the second battery, the positive terminal of the second is connected to the positive of the third; the negative terminal of the first battery is connected to the negative terminal of the second battery, the negative terminal of the second is connected to the negative of the third and so on. The batteries are connected: + to + to + and - to - to -. In this configuration, the capacity is the sum of the individual batteries and voltage is unchanged.
You cross the battery.
The negative battery lead cable is to be connected to the negative lead terminal on the battery.
The positive terminal of the battery would be connected to the positive terminal of the ammeter. The load would then be connected between the two negative terminals, positive side of the load being connected to the negative side of the ammeter.
The negative battery terminal is marked with an minus (-) sign on the battery next to the post. It is the one with the black cable connected to it.
I can if I charge 2 of them at a time. Most 24 volt chargers also have a 12 volt setting. What is hard to find is a 32 volt charger. We can charge a 12V battery with 24V charger, by connecting two 12V batteries in series i. e. the negative terminal of the first battery is connected to the positive terminal of the second, now the charger positive terminal is connected to the first battery positive terminal and the negative terminal of the charger is connected to the negative terminal of the second battery.
Yes
To jump start an engine via the battery; the remote battery and the host battery, being of the same voltage, should be connected in parallel. That is positive terminal to positive terminal, negative to negative.
when the positive terminal of the battery is connected to the positive terminal of the diode it is said to be in forward bias
A battery terminal or a battery CABLE terminal. If the terminal is gone or destroyed on the battery, you need a new battery. If the cable terminal is terminal, you can buy an after market replacement or a complete new cable with terminal at most any auto parts store.
Cars in which the positive terminal of the battery is connected to the chassis. They require specially designed components built for positive ground cars. The usual configuration is a negative ground (the negative battery terminal connected to the car's chassis).
