I mixed up connections of battery pole with ammplifier pole

I mixed up connections by connecting the positive pole of car battery with the negative pole of the amplifier and the negative pole of car battery with positive pole of amplifier and the amplifier did not give anymore power or the power signal does not give any more green or red lights. when connecting again properly, there is smoke coming out from the crocodile leads on the batery poles. what is the problem?

Check the fuse protection of your amplifier then replace it if blew up..but if still blow again some parts in you amplifier was damaged...like choke filter coil in DC section of your amplifier...look for elec..tech..to repair your amplifier.

Which is the positive terminal?


There may be a dot of paint identifying the positive terminal. An old trick is to connect the negative pole of a flashlight battery to one terminal and briefly touch the top pole of the battery to the other terminal. If the cone moves outward, you have found the positive speaker terminal.

After changing the battery there is no heat or air


When you change the battery, you should take off the negative
pole first and then disconnect the positive pole. wait at least 30 min and connect the positive pole first and the negative last.
Sometimes you have to drive your vehicle at least 10 miles so the car computer will acknowledge the change.

Find a positive full time power and a acc positive


Usually modern cars have this wires in the DIN connector of radio slot, battery (yellow wire) & under key (red wire), if you need more power to powering an amplifier or other heavy electrical load you can connect a wire directly to battery positive pole, the negative can be connected directly to car chassis, be sure that the wires used for this last application are at least 4 mm of diameter.

2011 SEL. V6 Duratec DOHC. After battery change,AC only blows hot air, compressor working. Followed instructions in manual for resetting idle and fuel trim. Did it 2x, but still no AC.


You may want to disconnect your battery again, First Disconnect the Negative pole first then the Positive pole. Wait 20 to 30 minutes and connect the Positive pole first, Make shure that you disconnect the Negative pole first and connect the Negative pole last. This will give the vehicle's computer a chance to reset the settings. You may have to drive your vehicle for 10 miles or more to see if this advice worked. If not, go toyour local Automotive store to seek advice, specially Auto Zone.

I need a simple wiring diagram to turn on 40 red leds and 40 green leds on a 9volt battery


Two ways to do it..........

One is a Series circuit, the other is a Parallel circuit.

Of course you can also use a Series/Parallel circuit.

Each LED has a Positive ( + ) connection, and a Negative ( - ) connection.

A) Series circuit:

One side of Switch is connected to Positive ( + ) of the Battery.
The other side goes to the Positive ( + ) of the first LED light.

Then the LED's are connected together in a Series.

Negative of first LED light to Positive of second LED light.
Negative of second LED light to Positive of third LED light.
Negative of third LED light to Positive of Fourth LED light.

And so on, and so on, until you come to No.40 LED light.
It's Negative connects to the Battery.

ONE LED goes bad, and none of them will work.
Old Christmas light strings are set up this way.

B) Parallel Circuit:

Switch to Battery - Positive ( + )
Wire goes from Switch, to 1st LED light's Positive connection ( + )
Then wire from 1st LED positive, to 2nd LED Positive ( + )
Then wire from 2nd LED Positive to 3rd LED Positive.

And so on, and so on, until you reach the 40th LED.

Then wire comes from Negative ( - ) of Battery, to Negative of 1st LED.
Wire from 1st LED to Negative of 2nd LED.
Wire from 2nd LED to Negative of 3rd LED.
Wire from 3rd LED to Negative of 4th LED.

And so on, and so on, until you reach 40th LED.
Wire connects to Negative of 40th LED. Then a wire connects from 40th LED Negative, and goes to Negative of Battery.

http://en.wikipedia.org/wiki/Series_and_parallel_circuits

Series Circuit;

http://en.wikipedia.org/wiki/File:Series_circuit.svg

Over to the Left side you see the Battery symbol. There is no switch in this circuit.

In the Battery symbol, the Longer line represents the Positive pole.
(Positive connection)

Resistors are represented by the squiggly lines. In place of them put your LED lights.

A Switch would go in-between the Battery, and first LED light; on the Positive side.
(ALWAYS put the Switch on the Positive side. Can explain in detail if you need)

[The Top line in the diagram, is the Positive 'wire' ]

http://www.autoshop101.com/trainmodules/elec_circuits/circ114.html

Parallel Circuit:

http://www.autoshop101.com/trainmodules/elec_circuits/circ122.html

In a Parallel circuit, if one LED light goes out, the rest stay on.

I have a 1996 hyundai accent it ran fine took battery off and put it back on now no spark and wont start


Check the ground wire, a black connected to the ( - ) pole, it might have been disconnected. Clean the battery clamp and battery terminals from rust and oxidation, tighten up the TERMINAL. Remember ( + )positive pole is RED and negative ( - ) pole is black, sometimes no plastic cover!
Taaah!

On a battery for a 1994 BMW 530 Touring, where are the negative and positive poles located when battery is in place, under the rear seat?


Golden rule with batterys..

The Positive terminal is ALWAYS physically larger that the Negative.(ie larger battery post ) The Negative will be the EARTH connection ( bolted to car body and engine) There may be hard to see (-) or (+) on battery leads . Colours do not matter either as manufacturers vary on this !
Good Luck

Won't start


It is usually marked on the casing. +(or a red marker around the pole) is positive. If you havent removed the battery connect a bulb between one of the poles a piece of bare metal (ie engine). If the bulb lights up you're on the positive. If you have already removed the battery use a multimeter and measure voltage across the poles on the battery, if the meter gives a positive reading the red test lead is on the positve. If it gives a negative reading ie -12.35V(digital meter) the red is on negative. If you have an analogue meter(a meter using a needle) it will swing to the left when red lead is on neg.

Where to connect jumping cables on the battery


Dead car --- Red to + ... Black to -

Hot car --- Red to + ... Black to any metal car part away from the battery. Let the hot car charge the battery for a couple minutes before you try it. Try it. IMPORTANT: DISCONNECT THE HOT CAR BLACK JUMPER FIRST, then take the black off the dead car. Then disconnect the dead car red and then the other end on the hot car.
