Car Battery Cable Order: Which to Connect First

When jumpstarting a car you essentially give the dead battery just enough boost to start the engine and then rely on the alternator to charge the battery the rest of the way. When using a battery charger, you allow the battery to charge all the way before it will be used again. This should answer important questions such as what the voltage requirements are for charging your battery and whether or not you should remove it from the vehicle before charging. There will be a manual with your battery charger that provides details for the appropriate use of the charger. Working in a well-ventilated area will help dissipate the hydrogen gas that batteries generate from the sulfuric acid within their cells. Also, make sure to keep any other volatile substances, such as gasoline, flammable materials, or ignition sources flames, cigarettes, matches, lighters away from the battery at all times. Glasses, gloves, and other protective gear is a good precaution. Hydrogen released within the battery quickly converts to a gas and expands, this can cause the battery to explode if venting mechanisms fail. These accessories draw power from the battery and should be turned off before removing or charging the battery. Most batteries will be found either under the hood of the vehicle or in the trunk.

By Jasmin Radoncic Aug 10, My younger brother is 17 years old and just got his driver’s license. Before he was able to take the car out alone, my father and I made sure he knew what to do in emergency situations. Our first lesson, which I’ve repeated below, was on how to use jumper cables. How to use jumper cables: Before trying to jump start the car make sure a “dead” battery is your problem. If you turn the key and your car does absolutely nothing, then there’s a good chance the battery is dead, however if you turn the key and you hear the engine cranking then your problem is most likely something else.

Proper way to hook up jumper cables – Want to meet eligible single man who share your zest for life? Indeed, for those who’ve tried and failed to find the right man offline, relations can provide.

This can cause the catalyst to stop doing its job. Your emissions will get worse and eventually you can lose the certification. Once the car is up to speed, jump in; press clutch, put in second, release clutch. Otherwise you won’t be able to create enough speed and steer the car securely at the same time. If you are outside the car and need to brake you are screwed anyway or if you never tried it, jumping in a driving car you could break your legs and then lose the car because it keeps rolling.

You do have to push with the door open and a hand on the wheel. Obviously better to have help. And be nimble on your feet and strong. Not for the unathletic. A quick google search for “jump starter battery pack” will show many options and price ranges. They’ll often be able to inflate tires, charge phones and other handy utilities too. You clamp it on just like you would a jump start with another car and start, but you might not want to keep them attached too long.

I have one that has saved me misery many times, but remember to check the charge frequently as the batteries do drain even when not in use. I fine mine should be charged maybe every two to three months and gets 3 jumps on a battery but YMWV.


This is a battery terminal puller. It cost a couple of bucks. The arms arrow go underneath the cable end clamp, and the center pushes against the terminal post on the battery. Turn the handle and the cable end clamp lifts right up. Then the battery cable can be pulled away. I’ve had a battery cable spring back and touch the battery terminal.

How to connect jumper cables and how to jumpstart the car Photo 1: Hook-up at the weak battery Connect to the positive cable to the positive terminal of the weak battery.

Hook up to the one battery on the driver’s side – DO NOT hook up to the battery on the passenger’s side. Never “fast charge” a battery if you plan for it to live a normal life. Don’t disconnect the battery cables. And never plug in the charger until after you have the charger cables connected to the battery. Connect the positive cable on the charger to the lead part of the positive battery cable on the driver’s side battery. Connect the negative cable to a good ground somewhere near the front of the engine bay.

Safety czars say to never connect to the negative post on the battery, but the reason is if you have a defective battery that is spewing gas, it could blow up because of any spark as you touch the cable to the battery post. But I have charged dozens of car, tractor and equipment batteries – including my PSD – by connecting to both posts with no problem.

The main caution is don’t get in a hurry. It takes several hours to charge up the two huge batteries in our trucks, so use an automatic charger set on 15 amps and leave it on overnight. By next morning it should be down to about 2 to 5 amps “trickle” charging rate. Then be certain to unplug the charger from shore power before you disconnect the negative charger cable from the truck.

Its a computer controlled 3 stage smart charger. This is the one you get if you have 2, 4, 6, 8, 10 golf cart batteries in 1 bank and you want to put energy back in them as fast as you can from a generator, or other power source.

May 03,  · Best Answer: Check all fuses first to see if any are blown, there is a fuse box under the hood and one inside the car in most vehicles. Yes hooking up jumper cables wrong can do lots of harm to the entire electrical system. Sometimes it only takes out individual components, sometimes it can fry the ECU, and it can take out the alternator : Resolved.

It shows on the picture by the two AC outputs 7 and 8. I cannot find a download for the manual so I cannot confirm that both of these AC outputs are milliamps but this is what it looks like from the data on their website. Will this damage the unit? The amp comes with FX loop but currently my new setup is running everything upfront. I only want to gate my drive pedals and vibe. The pedals in use are as below:

How To Charge a Car Battery and Jumpstart a Car

Optical audio cables are a great option for any home theater or audio system. These cords use light to transmit the audio signals from the audio source to the receiver, and because of this, they are not affected by any electrical interference. Optical audio cables, also commonly referred to as Toslink cables, are especially recommended for old homes where there are more chances of electrical leaks due to the accumulation of moisture.

Optical audio cables also provide far superior audio quality as compared to standard coaxial cables.

What is correct way to hook up jumper cables on RAV4 And is there a way to connect the jumper cables without taking off the battery cover. We know from earlier experience that taking off that cover is a major ordeal even for someone who knows what they are doing.

The reason that you typically run multiple batteries on an engine is that you need the cranking amperes to start the engine. You have twice the amperes with the batteries in parallel, but the voltage of the system operates at the battery nameplate voltage in this case, 6V. In series, you double the voltage, but the system can only produce the nameplate amperes of a single battery. I suspect that these batteries are installed in parallel. With that in mind, a single charger should be installed on the system at 6V, but the charger current shouldn’t exceed the wire rating of the system.

The best way to install it would be by tying your charger positive to battery A positive and your charger negative to battery B negative. Since your batteries are on opposite sides of the tractor, that may be tough and you probably are fine to just install your charger to one battery positive and negative or tractor ground and it will charge both batteries. Operating two chargers in parallel simultaneously as stated by the poster above is not my recommendation.

Number one, you may be spending twice as much money as is necessary and number two, if the chargers aren’t operating at the exact same voltage in parallel, that imbalance will manifest itself as a stray current in your wiring and batteries, potentially causing thermal stress on the system. Probably not a big deal, but most small-time chargers aren’t built to the tolerances of high dollar industrial chargers and the bigger the difference in voltage, the greater the stress on the system.

At home, you can charge it using your battery charger, but if you are out on a trail or at a campsite, it can be scary when it won’t start. But all is not lost. There are a few ways you can get your ATV battery going again. What happens is you get the wheels moving, and that can trick the engine into rolling over. Once it is on, it will charge the Battery as you drive. Turn on the key or switch and put your ATV into first gear.

It is not difficult to jump start your car the correct way, once you know how. Pull the car you are using to jump the dead battery in front of the car with the dead battery. The vehicles need to be close enough for the jumper cables to reach, but do not let any parts of the cars touch each other.

January 19, 3: I Have monster clarity one speakers powered. I want to add in a powered subwoofer. The clarity ones only have various inputs – no outputs. The sub has speaker level in, speaker level out, rca in. What is the best way to hook them up? The signal is not coming from a receiver but an ipod, my laptop, etc. Should I split the signal? If so, should I use the line level rca plugs or the speaker level speaker wire plugs? If not, should I run the complete signal to the sub rca?

Just get a 3. They are powered speakers so I am wondering if running the signal from the speaker level out of the sub to the speakers. Will it work properly? From everything that I’ve read it seems the best way to do it is to split the signal at the source and run a seperate signal to the speakers and the sub.

Should I be concerned about the inrush current when connecting portable bank into stationary bank while battery charges are equalizing. Can a resistor be added to cable to slow current while banks are equalizing. If so where in connection and what value would you recommend.

Jumper Cables. Any pair of jumper cables is better than not having any at all. But if you are buying new cables, look for ones that are 4 to 6 gauge in size and at least 20 feet in length.

Strip back the cable jacket approximately 1 inch. Use the cutter provided with the crimping tool or strip by hand. Be careful not to nick the individual wires. Un-twist each of the 4 pairs and straighten each wire as much as possible between the fingers. Step 4 Use the B wiring scheme on both ends for a standard patch cable. For a crossover type cable use the B scheme on one end and the A on the other end. Step 5 Bring all of the wires together as closely as possible.

Hold the grouped and sorted wires together tightly between the thumb, and the forefinger. Use a sharp cutting tool so as not to “squash” the wire ends. Step 6 With the connector pins facing up, carefully insert the wires into the connector. Apply a moderate amount of force in order to properly seat the wires against the contacts in the connector. Alternate for “load bar” Type Connectors A. Note that the loadbar has slots on one side with a flanged edge on one end. The sloted side should face the pins inside the connector.

Jumping starting battery with trolling battery?

On the other hand, the augmented leads-aVR, aVL, and aVF-are unipolar and requires only a positive electrode for monitoring. Einthoven’s Triangle The Einthoven’s triangle explains why there are 6 frontal leads when there are just 4 limb electrodes. As a result, they form an equilateral triangle. Keep in mind that RL is neutral also known as point zero where the electrical current is measured.

I always hook up the cables to the dead battery first then hook up the good assist battery, this way you’re away from any potential hyd explosion, also if someone isn’t careful and while you have the dead battery hooked up to the cables and the other two cable ends touch each other, the spark and potential damage will be less severe than if.

She asks you if you can give her car a jump. You look down at the ground, kick some rocks, and offer to call AAA instead. You have no clue how to jump start a car. Every man should know how to jump start a dead car battery. Ground the positive cable on the car with the good battery? Red cable is negative? Make sure both cars are turned off. Connect one end of the red positive jumper cable to the positive terminal on the stalled battery.

Connect one end of the black negative jumper cable to the negative terminal of the good battery. Somewhere on the engine block is a good place. Unless you want to see flying sparks and a possible explosion, do not connect the negative cable to the negative terminal of the dead battery.
