How to jump start a vehicle safely

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 NOT to 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.

Dead battery, used jumpers. Lights work dashboard lights up. Motor will not turn over


If the battery is very dead, it can take a while for the dead battery to regain enough charge to start. If you are jump starting from a jump box and not a running vehicle, there may not be enough power available to get the charge to a level that can start the vehicle. Hook up the jumpers cable to a running vehicle and allow 10-20 minutes for the battery to gain some charge. Monitor both batteries carefully during this time and should any unusual amount of heat or if smoke starts to come from either battery, shut everything down and disconnect as quickly (and safely) as possible.

radio wont work


Blew a fuse is likely problem, especially if you did not jump it correctly. Cannot tell you how many times I have walked up to people in parking lots to potentially save their life and/or limbs. Connecting a dead battery to a live battery wire to wire is just plain dangerous. Start at the dead battery. Connect the red cable to the red (+) terminal on the dead battery. Connect the other end of that cable to the red (+) terminal of the live battery. Connect the black cable to the black (-) terminal of the live battery. (CAUTION: Before making this connection, make sure the other end is not touching a ground). Finally, connect the last connection to the dead battery's car on a good unpainted grounding point away from the battery if at all possible. A usually good point to use is the area where the hood latch is located. Small sparks will let you know it is a good ground. Start the live battery's car. Let it run for about 5-10 minutes with all lights and accessories turned off in both cars. Now attempt to start the dead battery car. Disconnect in reverse order. Good luck and be safe.

chevy troubleshooter. Car wouldn't start got it jump went to shop nothing wrong with battery or altnator or connections car started fine a few times then it took a few seconds to connect something isn't right


Hi Linda, I'm glad to help!
If I'm reading you message right, your cars battery is going dead and you must jump start it to get it to run. Here's the thing, a cars battery and alternator can be just fine. BUT, the system can still have a draw coming from somewhere that can draw all the power out of the battery and thats why you need to jump it. This can happen intermittantly as well making it almost impossible to find the draw. If this is whats happening then your mechanic will need the vehicle for awhile to find the draw. I'm not there so its hard for me to say this is whats going on, but it's a good place to start diagnosis. Hope this helps and have an awesome day Linda!

I have a 2005 Jaguar S Type and want to know if I can jump start the battery like you do other cars?


It can be jumped. Check for remote jump starting posts under the hood. If there are none, then whichever is easier: jump the battery or remove it and charge it up.

what is wrong when you turn the key to start and the radio and all the instruments turn on but the starter doesn't click and the engine doesn't turn on even after trying to jump start it


Dead battery

Dangerous practice to try & jump a dead battery

The battery cables could be loose at either end or corroded internally

Most likely the battery is worn out, if original to car
since it was new, or the starter solenoid is worn

You do not want to jump any vehicle made after the
year 2000 or your asking for possible problems with
todays electronics.

You need a good battery that has been tested & fully
charged, then only jump with a jump pack,not another car
