What happens when you inadvertently crossed the positive battery terminal from a negative to a positive and a positive to a negative.?Read more: What_happens_when_you_inadvertanly_crossed_the_positive_battery_terminal_from_a_negative_to_a_positive_and_a_positive_to_a_negative.
Look at the battery cables, if the positive goes to the frame, then the entire sytem is a positive grounding sytem ,including the charging system. Mark Great simple answer Mark. This will also be of great help to you. An online 1941 Chevy Shop Manual. http://chevy.tocmp.com/1941shop/index.htm
If you connect the positive and the negative end of a battery directly with a cable, (1) you'll get dangerously high currents, and (2) the battery will quickly run out of energy. The battery itself might also get damaged, due to the high currents.
Depending on colours of course black is usually negative and the other colour (generally red but depends) is positive. Get a D-cell Battery. Now get two pieces of speaker wire. hold one wire on the positive terminal of the battery and hold the other on the negative side of the battery. touch the wires to the positive and negative posts on the speaker. if the cone moves out ward the positive and negative are correct if it moves inward then the positive and negative are reversed (out of phase.) this simple test will allow you to see which terminal is which.

The negative battery terminal is on the battery. They don't have a wire coming from it like they do the positive. For charging purposes, the engine block acts as the battery ground. When disconnecting the negative at the battery, the negative terminal usually has a black wire and the positive has a red.
To charge a car battery with a DieHard charger, first ensure the charger is unplugged. Connect the red positive clamp to the battery's positive terminal and the black negative clamp to the negative terminal. Plug in the charger and select the appropriate charging mode, if applicable. Monitor the charging process and disconnect the clamps after the battery is fully charged.
As the battery charges, the negative plate changes to metallic lead, and the positive plate change to lead dioxide.
Charging system voltage is too high or to low.
Negative battery or jump start post.
Yes, you can use jumper cables to charge a 12V 4Ah battery with a 12V 5Ah battery, provided the 5Ah battery is fully charged. Connect the positive terminal of the charged battery to the positive terminal of the 4Ah battery, and the negative terminal of the charged battery to the negative terminal of the 4Ah battery. However, this method is not ideal for charging as it may not provide a controlled charging rate, which can potentially harm the batteries. It's better to use a proper battery charger for safe and effective charging.
When charging a car battery, you should always disconnect the negative terminal first. This helps prevent any short circuits or sparks that could occur if the positive terminal is disconnected first while the battery is still connected to the car's electrical system. After charging, reconnect the positive terminal first before reconnecting the negative terminal.
Positive to positive, negative to negative if you are asking about installing one battery in a vehicle.
When charging a car battery, connect the negative cable to a solid, unpainted metal ground on the vehicle, such as a bolt or bracket on the engine block or chassis. This helps avoid sparks near the battery, which can be dangerous due to flammable gases. Ensure the positive cable is connected to the positive terminal of the battery first before connecting the negative cable. Always follow safety precautions and refer to your vehicle's manual for specific instructions.
Energy flows from the negative terminal to the positive terminal of a battery.
