This is normal so you have no worries its Normal for this to happen just make sure that the batter cables of negative and positive one has no acid on both of them and make sure that when you put them on the battery terminals that the cables are tighten real good. You can go to autozone and buy a liquid that you can put on your battery terminals so they will not add any acid to it.

1988 Dodge d100 my lights are flickering


It's a battery or ground problem. You mean all of them, headlights, dash lights, or what? The flickering is often caused by a corroded or deteriorated ground point for the lights, less common is a hot wire connection that is loose or not contacted well. Your headlights and front park lamps and any side marker lamps, I think they would all have a common ground, or maybe each side has it's own ground up front there. I'll try to find a wiring diagram for what you need, in the meantime, take off first the negative of the battery and then the positive post (for safety, always remove the negative first and reconnect negative last), clean both battery posts and the end of cables or the clamps that go on the posts. Any corrosion, green or white colored, is not good, and can lead to serious resistance in the connection, and hinder the electrical system. Those connections must be clean and tight, remember positive hooked up first, then deal with the negative post. Your truck is old, subject to rust, better check all your ground connections. The original negative cable had a large ground to the engine block and a smaller wire ground to the body, somewhere grounded in front of the battery to the frame. If rust is an issue, you can always find a better ground point-to clean metal free of paint.

If you know all this and you know the battery connections are clean and tight, then look for the ground point for the flickering lights in question. If you have a voltmeter it is almost essential to the testing or checking of any electrical circuit.

On the starter For a Hyundai accent which terminal should I connect the red battery cable


Good question, because connecting it the wrong way can damage the starter, the battery, or both! The red cable connector clamps to the positive terminal, and the black cable clamps to the negative terminal. On a new battery, it is often easy to tell which is positive by their markings (+) = positive and (-) is negative. In reality, the markings may be difficult to see. The red or positive post is larger in diameter. The black or negative post is a ground so you can follow it from the post to somewhere solid on the metal frame of the car.

Note the cross on the top of the battery post.

According to In.answers.yahoo.com :

"...the battery case will have a + near the positive or a - near the negative terminal. If these don't exist then the positive post will have a larger diameter post than the ground post, this is if the battery is a top post.



If it's a side terminal battery which GM cars used for a while it should be marked on the top of the battery or on the front with its respective sign. Otherwise you can look at the cable that's connected to it which are usually color coded. Red is positive and black is negative."

Bought a 2002 ford escort zx2. Think they crossed the battery wires,need a picture of correct wire connections to battery


The battery has a positive (+) post and a negative (-) post. The negative post would have a cable, usually black, going to a ground, either on the engine or bolted to the frame near the battery. The positive post will have a usually red cable, and the cable will run from the positive post to the starter on the engine. If the wires, or cables, are wrong, it can be big trouble-fuses can blow, fusible links can melt, electronic components can be damaged, alternators can be snuffed out, ...big trouble!

Soon as I start car sometimes all lights flicker and sometimes while Im driving lights flicker and car shuts off starts back up car is 99 buick lesabre


Check all your ground wires. There will be several wires connecting
ultimately to the negative side of the battery. Usually at least 2
wires are connecting the body of the vehicle to the negative side
of the battery. Generally, the lights are grounded to the body which
is grounded either to the engine block or directly to the battery.

I have 91 Previa and about a week ago I was at a stoplight and the battery light flickered on and then my van lost power and died. I bought a new battery and all seemed well until 2 days later when


Hi

Yes it sounds like the alternator voltage regulator is wearing down and needs to be changed or replaced.

If you can get your hands on a 12 volt multimeter, turn the setting to 20 dc and place the negative wire on the negative battery post and the positive wire on the positive battery post.


The battery with motor off should be 12.6 volts and higher, start the the car the read out should be 14.,2 or higher.


You can turn the lights and heater on to see if the alternator can cope with the load.


if read out is less then you need to change or replace it.

Cheers

The manual for my '07 M6 says to charge the battery using the posts under the hood. I have located the "+" post but it doesn't look like what I am use to seeing. Where should I connect the...


On the newer model cars they have started putting the battery under a myriad of plastic covers to make the engine compartment look cleaner. The "+" post that you have found is directly connect to the positive terminal on the battery. Put the positive cable on that post and then the negative on a bare bolt that is connected to the frame of the car, I would use the one on the sway bar if possible.

Were is negative. Battery post


The negative battery cable is black and the positive battery cable is red.
The positive battery cable will lead to the starter while the negative battery cable will connect to the body of the car which is negatively grounded.

Always remove the neg. battery cable first, and then the pos. battery cable second. And install in the opposite direction, pos. battery cable first, and then finally the neg. battery cable to the battery.

Also, many batteries have the (+) and (-) posts labeled in an embossed fashion on the plastic case.

Do not reverse, or else the vehicle's electronics can be fried.

Good luck on this repair.

Dad's Dodge Durango light problems


The proper way to jump start is to start the car that is doing the boosting first then connect the cables, making sure that the polarities are right, negative to negative and vice versa. The reason for this is that while cranking the car doing the boosting, the the car with the low battery suffer a significant voltage spike since the sudden draw of current will pull the voltage down on a weak battery, and when the car do start, the voltage suddenly goes up, adding to that, the alternator bring the voltage even higher. Electronic circuits are sesitive to these voltage spikes. Still I doubt your problem is caused by these unless theses things you are having problems with are controlled electronic,.
