How to hook up dual batteries

Next If you drive a car, you need to know how to use a pair of jumper cables. Maybe you left an interior light on or your battery has simply reached the end of its life. Either way, car batteries don’t typically give you signs of trouble until it’s too late, and then your car just won’t start. So no matter how old or new your car is, owning a working set of jumper cables — and knowing how to use them — is a must. First you need the right pair of cables. When you really need them, any set is better than none at all, but if you’re buying new jumper cables, Popular Mechanics suggests ones that are 4 to 6 gauge and at least 20 feet 6 meters long. Those extra-long cables will come in handy and make connecting batteries easier if you can’t put two cars directly next to each other. Also look for jumpers with thicker cables and heavy clamps. They’ll be more durable and last longer. Of course, when it comes time to jump your battery, it’s very important to handle the cables properly.

The good news is that if your ignition switch was turned to the “off” position when this happened, the fix may be simpler and cheaper than you think. This car has one or more “fusible links” in its primary wiring. They may look like a thick piece of wire, but they act as super-fuses in the the case of large-scale power shorts and the like.

Fusible links are typically in-line, so you won’t see them in either your under-hood or under-dash fuse boxes. If you’re lucky, you blew a fusible link right off the bat, saving the rest of your electrical system from serious harm. If your ignition was turned to the “on” position when the battery was hooked up backwards, you have a more serious risk that you damaged your on-board computer. However, even if your computer were fried, your dome light, your hazard blinkers, and probably your headlights and turn signals different circuit than the hazard lights, believe it or not, even though it’s to the same bulbs would continue to operate.

I’m going to recommend that you should check for one or more blown fusible links. Posted on May 09,

Are they dim or bright? Note that in some cars you will need to turn the ignition on to test the headlights. If they are dim, it’s likely your battery is the culprit. If your headlights are bright, you do not have a dead battery and a jump start will not help. Put the key in the ignition and see whether your dashboard lights up as usual.

In most cases, even with a low battery you should see some dashboard lights and get some sound out of the stereo. If you do not get a flicker out of your dashboard, you may have a problem with your ignition switch. Try to start the car. Does it turn over very slowly, or does it crank quickly?

I’ve got a car in a garage that I cannot get out of park in order to push it back out , and its battery is dead because I left a light on. I have two jumper cables that, combined, would be long enough to reach another car parked right behind the dead one.

Can I simply clamp the two cables together? Or will I have to go find a longer one? Yes, should work fine, just be careful not to let the red clips touch the black ones. But the point about keeping the red and black clips separate is critical. It would be a lot easier to just connect the two sets of jumper cables, rather than swapping batteries back and forth.

Generally, you only make this mistake once. This can either be side-by-side or hood to hood. Just make sure they are close enough for the cables to reach both. Take out the cables and make sure to never touch the ends to each other at any time. First work with the running vehicle.

The thing about jumper cables is that the thicker they are, the more electrical current they are going to allow through, but they are also going to be heavier, more difficult to maneuver, and the parrot jaw will have a more difficult time staying attached. So a 2 gouge wire is the optimal choice because, with most light cars, that is anything weighing less than a ton and a half, they will allow enough current to pass from the donor car that you should be able to start the dead battery car within a couple of minutes.

The Cal-Hawk wires use a special type of branding and extra slick rubber insulation so they do not get tangled and they were designed to stay flexible even in degrees Fahrenheit. And the good news is that, even with big, heavy trucks, as long as the dead battery is not completely gone and can still hold its charge, you can use a donor car to bring back to life the battery by running the engine for about 15 minutes, and then you should be able to start it, while the 2 cars are still connected without any worries.

So what you will need are a set of jumper cables with a 4 gauge like the Coleman Cables. As long as you connect your truck to another powerful engine, you should be able to start in less than 5 minutes, or you may be able to start right off the bat. There is another interesting feature that attracted us to the Coleman Cables which is the fact that the handles glow in the dark so, it is very easy to get the polarity right even in complete darkness.

The Hurricane season is here for those of you in the east and down south. I hope that this article will help all of you to be more prepared in the likely event that power failure occurs. Here are some helpful tips about running an inverter during a power outage. Before you purchase an inverter you will want to take a piece of paper and a pen and write down all of the appliances that you feel are necessary to have during a power outage. After you write down all that, you need to go to each one of the appliances and look on the back or bottom for what is called the service tag.

This tag will show you a few important specs that help with picking the correct size of the inverter. The first spec that you will most likely come across is the voltage; this will either be , , or vac. In some cases you may find that the voltage is between vac and vac. You will need a special inverter to run this appliance. We will get to that later. The next spec you will find will be the Amps.

For example this should read like this: What you will do now is take the volts–lets say and multiply by amps 6. Ok, Now that we got that out of the way we can start sizing an inverter that is going to work well during a power outage.
