I'm not sure on this one but unless you've got something that runs all the time, you shouldn't. But, it does sound like you're making a mistake anyway. You should ALWAYS CONNECT THE POSITIVE POST WIRING FIRST. Connect the negative LAST. Disconnect any battery the opposite of this, negative first, positive last.

The reason for this is primarily so you don't strike an arc while removing the battery and having a battery blow up in your face. I know from experience, a battery will blow up. When they're in a discharged state, they 're full of hydrogen gas, a flammable gas. One little spark with a small hydrogen leak, bang, your eyes are full of sulfuric acid.

If you installing a new battery and connect the negative first, a slip of the wrench and you've got a hole in your oil tank. Not something to end your day with.

So, disconnect your negative first, connect your negative last.

If your bike is computer controlled, you may be seeing the arc of the required current to hold the memory. Like I said, I'm not really sure on this one.

Case w20c weel loader positive battery terminal is burning off


to burn the positive terminal it indicates that the terminal was not clean and tight and the resultant arcing has melted the lead terminal
there would be a very high current for the electrical power steering hat would contribute to the problem so check the current draw for that unit as well

Tip

Jump-start Jaguar X-type? it's more complicated than you think.


Jump Start of Vehicle Battery


IF THE BATTERY YOU ARE USING TO JUMP-START THE VEHICLE HAS RECENTLY BEEN CHARGED IT MAY STILL BE GASSING, COVER THE VENT PLUGS OR COVERS WITH A DAMP CLOTH TO REDUCE THE RISK OF EXPLOSION SHOULD ARCING OCCUR WHEN CONNECTING THE JUMP LEADS.

Turn off all electrical ancillary circuits such as radio, lights, indicators etc. If the reason for a flat battery is unknown the condition may be as a result of an electrical short circuit, so care must be taken during the Jump-start process and subsequent to connection to ascertain if this is the case. A short circuit or un-isolated ancillary load can cause arcing when the jump leads are connected, a small 'crackle' is normal but any spark or flash is an indication of a problem that should be rectified before attempting to Jump-Start the vehicle.

Jaguar do not recommended that the vehicle is jump started, and If at all possible it is preferable to replace the flat battery with a suitable fully charged unit rather than jump-start the car. However if it is done it should be carried out by suitably qualified personel. Garage services and services like AA and RAC homestart should be used whenever possible.

Obviously there are occasions when carrying out this proceedure yourself is the only practical way proceed.

If there is no option but to jump-start the discharged battery should be removed and recharged immediately after jump starting to avoid permanent damage.

High quality, heavy duty Jump leads must be used as the current consumption during starting is very high, and a voltage loss will be
exhibited though the jump leads, increasing current requirement.

Make sure that the Jump Start battery is of the same voltage as the vehicle, and suitable to provide the required starting current.

MAKE SURE THAT THE ENDS OF THE JUMP LEADS DO NOT TOUCH EACH OTHER OR GROUND AGAINST THE VEHICLE BODY AT ANY TIME WHILE THE LEADS ARE ATTACHED TO THE BATTERY. ARCING AND VERY RAPID DISCHARGE CAN CAUSE THE BATTERY TO EXPLODE.

Connect the jump leads in the following sequence.
Connect Positive Jump Lead to Jump Start battery positive terminal.
Connect Positive Jump Lead to Vehicle battery positive terminal.
Connect Negative Jump Lead to Jump Start battery negative terminal.
Connect Negative Jump Lead to a suitable vehicle ground point at least, 300 mm (12 in) from the battery terminal e.g. engine lifting bracket, do not do not connect directly to the vehicle battery terminal.

Start the vehicle and rev to 2000 rpm, then allow tickover for 5-10 minutes.

Do not attempt continued repeated starting of the vehicle, this will cause heat build up at the terminals and though the jump leads degrading the leads performance and adding to voltage loss.

Allow 3-4 minutes recovery time for the leads and Jump Start battery between attempts to start.

Before disconnecting the jump leads, switch on the heated rear screen, to reduce the alternator voltage peak when the leads are removed, as this can damage electronic equipment.

Disconnect the jump leads in the reverse order to the connecting sequence taking great care not to short the ends of the leads.

Do not rely on the alternator to restore a discharged battery.
Ensure that the battery is recharged or replaced with a fully recharged unit
as soon as possible.

Following Jump-starting of a compleately discharged battery, you may need to carry out a Green ECM drive Cycle, this will allow the powertrain control module to 're-learn' idle values, and most likely need to re-enter your radio code, details of these can be found at. http://www.bluejag.co.uk

Recharge battery Cadillac Deville 2005


You do not need to remove the battery to charge the battery. When you connect the charger you MUST be careful to connect the charger's positive lead to the positive terminal to the battery and the negative lead to the negative lead to the battery before you turn on the battery charger. Connecting the charger leads the wrong way around most likely damage the vehicle's electronics.
When you finish charging the battery turn off the charger before you disconnect the charger leads. This will prevent arcing between the leads and the battery.

Battery will not hold a charge--stator checks out ok--regulator rectifier ok, too any suggestions?


If you have had your battery load tested and it checks out fine there is a likely hood that you have something staying on. With the key in the off position, disconnect your negative battery lead and look/listen for an arc as you pull the lead away from the battery terminal. If you get an arc the next step will be to track down what is staying on. Good luck and happy hunting.

Just bought new battery. Charged fully & rode. Seems something draining battery after motorcycle is shut off Please advise where I can get free wiring diagram and also if you have any ideas to what...


Sorry, I don't have a schematic for this machine. If you have a digital volt ohm meter that will measure current you can see what it happening. Put your meters function switch in the "Amps" position. Plug the red meter lead wire into the "Amps" hole on the front of the meter.
Connect the red lead to the negative wire and the black lead to the negative battery post. If something is drawing current on your bike, you should have a reading on your meter. If you don't have a meter, just touch the negative lead back to the battery post and watch for a spark. The larger the spark, the more current it's drawing.

Now, to help in locating the problem. Take all the fuses out except the main fuse. Look at the meter or strike the arc. If you have none, start putting one fuse at the time in and checking for current flow or a spark. When you put one in and then show a current flow or a spark, whatever is drawing down you battery is on that circuit. You'll just have to figure out what is on that circuit and check each item.

Sorry but that's the best I can do this late model bike.

Good Luck
Steve

Trying to take negative clamp off battery, pos came off easy. seems to turn after i took the bolt off but just will not open enough to release off the battery. any ideas?


using a screw driver or chisel, find the small line where the battery clamp is joined in half. Put the screw driver or chisel on this line and strike with a hammer firmly. This will spread the clamp out. Also soak it in CRC or similar. You can also use the screw driver as a lever underneath the clamp. Ensure the positive lead is well away from where you are working. It is a good idea to wrap both the positive lead and positive terminal in masking tape to prevent any arcing out.

How to replace battery 2004 Mazda tribute


locate the battery under the hood. Most will have a metal strap across the top that keeps them in position. You will need a socket or wrench (i believe 1/2") to take off the 2 nuts that hold down the bracket. After that is off, remove the negative lead first (the black one)..NOTE: When loosening the nuts holding the leads on the battery, make sure you dont touch any other metal as it could cause an arc effect which you DONT want. After the negative lead is off remove the positive lead the same way. Pull the old battery out and put the new one in its place. Now connect your positive lead (RED ONE) to the post with the plus sign (+) make sure you secure it snug so it doesnt slip off or you'll short out the electrical system. Now connect the negative. Replace your bracket to keep the battery from sliding and you're done.

When attempting to jump start the vehicle positive battery cable heats up and smokes. What should be connected to the solenoid switch on the same post as the positive battery cable?


there should be charging leads from the alternator, and a feed wire leading to the main power/relay box just behind the solinoid. there might also be a few more leads depending on your truck. There should only be one on the other side leading to the starter. you need to replace that battery cable, a bad cable can cause symptoms similar to a dead battery

Intermitenly my headlights flash on and off.i already replaced the headlight switch. nothing noticeably consistant like bumps are causing this problem. just happens some times. increments are on and off...


Check if a relay exists, and if so, the contacts within could be arc damaged enough to cause intermittent failure (each time they open is a chance for arcing). Likewise, a potential arc failure site is the dimmer switch on the steering column.
...Could check if problem is up-system from the relay (if uses a relay), by placing a jumper wire (from battery or positive source) to the low current connector of the relay (which would be coming from the dashboard/column switching), in order to lock the relay to "on" (as if the interior light switch was now perfectly on).
...Similarly can check if relay by jumping across high current leads (should have the thicker wires that go from battery to relay and then high current lead of relay to headlights)

Battery arcs


you could have put in a shorted starter, or

you could have put the big wire to the ground bolt instead of the bolt at the starter solenoid.
