Understanding Battery Configurations

December 1, A friend needed a jump-start the other day. He attached the last negative cable to his negative battery terminal. I said he should have attached it to a metal surface other than the battery. You’re on the right track, John. But let’s go through the entire process since jump-start season is upon us. According to the Geneva Convention, the red cable is used for positive and the black for negative.

When it’s about Best Baby Jumper or Best Baby Door Jumper, it is very popular pieces of baby equipment that allow your baby to get some vertical exercise in a safe and protected way. Active babies sleep better at night, so it is beneficial to allow them to do some exercise during the day so they are ready to go to bed early at night.

Next A car battery contains chemicals that produce hydrogen gas during use. Hydrogen gas is volatile and has been known to explode under certain conditions, causing serious injuries. For example, a car battery may explode while starting the car, while jump starting or by carelessly shorting the terminals with a screwdriver. In fact, under certain conditions a car battery may explode while just sitting in a parked car or on a table [source: Keeping this mind, here’s how to safely use a car battery charger: Use the correct charger for your particular car battery.

Check the car owner’s manual for information or ask your car dealer or trusted auto mechanic. Read the charger manual and make sure you understand how the charger works and what precautions are necessary. Pay close attention to all the warnings. Remove both battery cables from the battery terminals. First remove the negative black cable and then the positive red cable.

Check that the charger is not plugged in to an electric outlet and that the power switch is off. Decide whether you want to charge the battery slowly trickle charge or quickly. Select a lower charging voltage and current for a trickle charge and a higher setting for a quicker charge.

Order in which to attach jumper cables when jumping a car

For other uses, see Jumper cable disambiguation. The alligator clips may be covered in insulation to prevent inadvertent shorting. Clips may be made of copper or steel. Jump start procedures are usually found in the vehicle owner’s manual. Owner’s manuals will show the preferred locations for connection of jumper cables; for example, some vehicles have the battery mounted under a seat, or may have a jumper terminal in the engine compartment.

Jumper cables should not be used to interconnect between different voltage systems.

QUESTION: I’ve got a Decimator G-String 1st version. My amplifier is a Fender DeLuxe Reverb reissue, which doesn’t have Fx loops ; so, I wonder if there’s a better way to connect G-String to avoid cutting off delays and reverbs’tail.

While batteries typically last five years depending on use and price , that time can fly by quickly — even faster if you accidentally left your headlights on overnight. Connecting the jumper cables the wrong way could cause a spark — and since flammable gases might be present in the engine around the battery, even a small spark could cause a fire. Here are seven simple steps to help get you and your car going again.

Before you attempt to recharge a battery, check it out. Most car batteries have a code date that tells you how old it is. It might not be safe to recharge it. Park the working car adjacent to the stalled vehicle. Put the emergency brakes on both vehicles and make sure they are both turned off. Your jumper cables should be able to easily reach both car batteries.

If not, try to park a little closer but make sure there is room for you to fit in between.

How to Use a Car Battery Charger

You will find this tool easy to use as there are colors to guide you, with red as the positive and black as the negative. These are tangle-free cables that are suitable for buses, tractors, and RVs. The 2-gauge heavy duty cables are made with solid and durable copper clamps, Thus, these can administer maximum contact, along with the serrated jaws.

Lastly, the rubber coating makes the cables non-slip to give you a secure grip for the connection. Some people were commenting on the overall quality of the clamps as lacking ample strength. But for the price you pay, these cables work as they should.

For the price I think this is as good as one should expect. The leads coming out of the wires are thinner than others I have and overall the wiring or cabling seems to be quite budget in material.

The answer ended up being a bit long, so I’m giving it its own page, rather than putting it in one of my serried ranks of letters columns. Something as beautiful as my original DIY UPS would, of course, be cheap at any price, but the thing itself didn’t cost me much. I had almost all of the bits sitting around already, and a local battery place gave me the slightly used fancy battery. This knowledge, of course, doesn’t help someone who’d like to build something like that for themselves.

But that piece is five years old, now; the build-from-scratch price today would be cheaper than it was then. And, because proper UPSes or SPSes , anyway are now also cheaper than they used to be, there are some good options out there for happy hackers who’d like to get a good standby power solution together on the cheap. But you can make a practical standby power unit on the cheap, if you start with a standard UPS with dead batteries. Today, lighter, cheaper and more efficient switchmode inverters are standard electronics-store products.

You don’t have to worry about an inverter’s output waveform for computer-powering purposes, because computer power supplies don’t care.

Why did my jumper cables melt : MechanicAdvice

West Fleet Direct http: To begin the install loosen the cap on the radiator overfill to remove pressure from the system do this while the engine is cool. Cut the hose closest to the drivers side It does’nt really matter where, I did mine about 6 inches after the fire wall. Then holding the ‘shut off valve’ with the vaccume controller twards the pass side install the portion of the heater hose coming from the cab to the top left nipple on the ‘shut off valve’.

Install the portion of the heater hose coming from the engine to the top right nipple and tighten the clamp. Next cut the heater hose closest to the pass side in the same location as the previous.

These are the cables that go into my wife’s car. I do trust her, but under times of stress, and having not done it much, it’s much simpler and pain free to only have to find the battery and hook the cables up .

SoCal – westsiiiide so, my FJ would not turn over today. I guess the battery just go to low as I turned the key and nothing. Anyway, no biggie as my buddy was over so we can just jump it. Got out the cables, he hooked them up and we went to jump it and the jumper cables started smoking at the connection points on both the FJ and the car – started to melt the plastic near the clamps. I have never seen such a thing. I looked at the cables and, not sure if it really matters, he had hooked up the ground to the – pole on the FJ battery and not grounded to the frame.

Source Jumping another person’s car without killing your own car’s battery is actually quite easy. With just a little bit of common sense, and the tips below, you’ll be jumping batteries like a pro in no time!

Yes, but it was scary! This usually happens either because the jumper cables are too short or because one or both vehicle’s batteries are located in awkward locations in the engine compartment. Regardless, if you’re unable to jump your friend’s battery without touching your car to theirs, then you’re going to risk killing your own battery.

Accessories OFF Whenever your radio, heater, air conditioner or other accessories on, you’re creating a load on your battery and alternator. They can take quite a load, but were not technically designed to handle a whole other vehicle’s electrical needs in tandem with your own. By turning off all your accessories, you decrease the load and provide your own battery and alternator with enough energy to jump another system without overloading itself.

Clean Connections If you want to protect your own battery while jumping another battery, one of the smartest things you can do is to make sure that all participating battery terminals are clean and erosion free. The same is true for the clamps on your jumper cables, as the cleaner your connections are, the less likely you’ll experience any negative draws or weak connections.

Good Vibrations In order to make sure you’re not putting the entire electrical load of another vehicle onto your own vehicle, make sure that your own vehicle is running throughout the entire jump. Buy Now I haven’t carried around actual jumper cables since

5 Ways to Keep Your Battery From Dying When Jumping Someone Else’s Car

Hydrogen gas is a byproduct of electrical energy created from a chemical reaction of lead plates submerged into the acid and water. Sparks can happen internally, too. Like when the lead plates warp from water evaporating out.

If your battery has died, you may be able to use jumper cables to jump start it from some good Samaritan’s vehicle. If you can safely use jumper cables on your vehicle, make sure that the battery on the good Samaritan’s vehicle has at least as much voltage as your own. As long as you hook up the.

How to connect the Inverter When does a small inverter’s power come from a 12V DC outlet and when does that inverter need to be connected to a battery? The basic decision is based on the maximum power the inverter will supply. That limit is set by the vehicle wiring and the fuse that protects the wiring. In practice, most fuses can withstand periodic over current by 10 percent or, in this case 18 Amps.

Furthermore, most 12 volt batteries actually deliver So, actual watts that can be delivered can be up to watts. Above watts of maximum power output an inverter has to be connected to a battery. This avoids fuses blowing in vehicular electric systems and the subsequent hunt for locating and replacing a blown outlet fuse. Battery clips are only used for brief temporary connections to a 12 volt battery. As with all connections to a flooded lead-acid car battery, follow the same safety procedures as you would during jump-start procedures presented below.

Connect the Positive battery clip to the battery positive terminal. Then connect the negative battery clip to a metal part of the vehicle frame. This sequence prevents a spark from igniting any explosive gasses that may be in the immediate battery area. Make sure the vehicle is parked in a location that does not interfere with traffic.


This was sent to me by Dave, thank you. I have been in commercial and private radio broadcasting for 25 years, and it’s time to dispel the myths about SWR and coax. Your coax is a vital part of the antenna system and must be tuned for proper operation. Even with the meter connected at the antenna, any change in coax type or length, will change the SWR reading on the meter. Your radio is reacting to the entire antenna system, including the coax.
