Why should a car battery's positive terminal be connected first for charging?
Batteries vent Hydrogen gas. You should always connect the positive battery cable first to avoid a spark at the battery that could cause the Hydrogen to explode. The negative cable should never be connected to the battery negative post. It should be connected to another ground area on the engine.
How do you hook cables to battery?
you hook the positive cable,(usually the red) to the positive battery terminal first then you hook the negative cable(usually black) to the negative terminal if you hook it the other way you can get sparks or arcing that can cause damage or a fire PS: if both cables are same color, the negative cable is the one bolted to the frame or the engine.the poitive is bolted to the solenoid or starter
Why can't i hook up the - part when jump starting?
The negative terminal is not supposed to be hooked to the battery. You always start with the positive cable, and then hook the negative cable to a peice of metal. Either the engine, block, frame, strut tower, something other than the starter. The reason for this is because when you hook up the negative cable, it can cause a spark, and also cause a explosion.
What terminal may course fire if touching the rest part of the car body?
Most all vehicles these days are negative ground so, if you touch a positive wire/terminal or cable to ground you can cause damage and possibly start a fire.
What will be the output voltage of two 12v batteries connected in parallel?
When two identical 3v batteries are connected in series with the negative terminal of one of them in contact with the positive terminal of the other the total voltage of the combination is 6v.
How do you remove the battery cables on an AC Delco?
I assume you mean the side post batteries used typically by GM vehicles. There is a small bolt in the middle of the side post terminal. Remove the bolt and the cable will be disconnected. NOTE! Remove the negative tereminal first to reduce the potential for shorting out your tools and potentially burning you.
When jumping a car why do you have to put the negative cable on ground?
You connect the negative cable last and connect it to ground rather than to the negative post of the battery because there may be a small spark when you make the connection. Batteries can emit a slight amount of highly explosive hydrogen gas. That spark on the negative post can cause these fumes to ignite and explode. That is why you always connect the negative cable last and always connect it to ground and not to the battery itself as a safety measure.
Why not clamp negative clamp to battery?
Because there may be a spark when you connect a jumper cable negative clamp to the battery post which can cause an explosion. Batteries emit hydrogen gas which is very volitive. Always connect the negative clamp to the engine or another ground point on the vehicle.
How to jump start car battery?
You have a dead battery and need a jump start. There is the right way and the wrong way to accomplish a jump start safely.Because of the potentially severe hazards due to improper use of jumper cables it must be done correctly. Auto batteries contain Sulphuric Acid which can blind you, or at the very least burn your skin. Also auto batteries vent off Hydrogen Gas which is highly explosive even from the slightest spark. Because of this danger it is critical to attach the jumper cables in a precise sequence.1. Park the vehicle with the GOOD battery close to the vehicle with the BAD battery but do not let the vehicle touch each other. Make sure the cables are not routed so as to touch any moving parts, such as a fan blade.2. Attach the jumper cable Positive + terminal to the GOOD battery Positive + terminal.3. Attach the other end of the jumper cable Positive +terminal to the BAD battery Positive + terminal.4. Attach the Negative - jumper cable terminal to the GOOD battery Negative - terminal.5. Attach the last jumper cable Negative - terminal to a heavy metal ground part of the engine and NOTto the dead battery Negative - terminal. Reason being this last connection will cause a spark, and you do not want a spark next to the battery where it could ignite the Hydrogen.6. If the engine of the donor vehicle with the good battery was not left running, start the engine and let it run for 2-3 minutes to put a charge in the bad battery.7. Start the vehicle with the BAD battery and then remove the jumper cables from the batteries in the exact opposite order you installed them.

What happens when you put the negative terminal on the positive terminal and the positive terminal on the negative terminal on a Mercedes-Benz s500?
It could cause the battery to explode. It can also destroy some of the electronics in the vehicle. In other words this would be a very expensive mistake.
Do you have to take out the battery when changing a high voltage car fuse?
Don't have to take the battery out but it should be disconnected. Carefully disconnect the negative (usually black) battery cable from the battery. Be sure you do not let the connector end of that cable or the negative battery terminal touch anything! (I put a heavy-duty plastic baggie over the connecting end of the cable & secure it with a rubberband. No baggie ties!) If the free end of the cable, or the disconnected terminal, touches anything conductive it will short out whatever it touches & could cause hundreds (or thousands) of dollars of damage. It could even cause an explosion if there is hydrogen gas accumulated near the battery, serious injury, or even death. Once the negative battery terminal is disconnected, there should be no electricitity flowing anywhere, & it should be safe to change the fuse.
