I tried to jump start my vehicle and put the jump leads on the wrong way( pos on neg etc..


Might of burnt all your computers. Are you able to turn lights on with the jumper wires connected properly ? Does your vehicle do anything with the key in the "on position" ?

How do you give a jump start to someone using a 2007 Dodge Charger?


The underhood connections can work by themselves...POS to POS, and NEG to NEG...sometimes dirty/weak connections do not allow the power to transfer fully from the underhood connections...if this is the case then you need to connect directly to the battery in trunk for full power charge...again POS to POS, and NEG to NEG...hope this helps

Convert battery cables from top post to side mount replacement ends?


If all you are doing is changing to a side post battery, just connect all the positive cables from the old pos post to the new pos holder and all the neg ones to the new neg holder. If you've already cut them all off and not sure where each wire goes, all the reds are positive, all the blacks are neg. To make sure use your continuity meter to test. Connect one meter lead to any good clean metal part on the car and test between each black wire in turn, the neg ones will show a circuit, the pos ones will not.

I've already replaced the starter, battery, terminal posts, and alternator. It will start of a jump after charging for about ten minutes but will not start when switching the batteries out. It just do


Could be poor battery connections or bad (corroded) cables. Put a voltmeter on the battery: ideal would be over 12.6 volts, if less than 12.2 volts, recharge battery.

If you have a voltmeter, google "voltage drop test" to see how to check for high resistance to current flow. Check the positive battery cable from battery to the starter. It may help you find a poor connection.

How do I open the trunk when the battery in the trunk is disconnected? Key fob and dashboard button don't work.


Get a pair of jump leads, either get under the hood or under the car, find the heavy cable to the starter motor, clamp the positive cable to it, ground the neg on the chassis, clamp the other neg to the help battery. Tap the remaining pos clamp on the help battery terminal to see if there is excessive sparking. If only a light spark or no spark attach clamp and operate trunk release as normal. If there is a big spark try option 2 which is make up a cable that uses the cigarette lighter socket, an auto parts house can sell you an adapter to suit the socket. Connect to another battery and there should be enough juice to operate the trunk lock. Take care.

Gauge showing low output alt only 1yr old wondering if it could be regulator or batt or wiring


if you have access to a digital multimeter, connect the meter (set to volts) across positive and neg. terminal of the battery, should read roughly 12.6 volts, close to 10 volts, battery may be going out, also test the alt output, disconnect neg term and place negative lead to battery neg post and positive lead to neg battery cable (make sure meter is set to amps) should read near the rating, if both those, then you'd want to do a resistance test, (set meter to Ohms) disconnect battery and connect meter neg to either pos cable terminal or where the pos cable connects to the alt and connect positive lead to opposite of neg, should read next to 0, the check resistance of the ground by connecting meter between batt neg cable and body of alt.

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.

What is malfuntion code P2127?


the (app sensor)accelerator pedal position. to test unplug the electrical connector at the accelerator pedal position sensor. Using a digital multimeter and with the key in the RUN position, check the Green wire for 5 volts (pos lead from meter to green wire, neg lead to ground). Then check the black/white wire for good ground (pos lead from meter on Green wire, neg lead to black/white wire)--should read 5 volts. Reconnect electrical connector to sensor.

Why did my car try to start on its own


Assuming that the solenoid was installed correctly I have to say that you purchased a faulty solenoid.

Where is negative connection for battery on 2006 dodge charger srt8


Also, to add to some mild confusion, the terminals under the hood on the charger are just there for a jump, thus there is only a positive terminal. The battery is actually stored in the trunk next to the spare.
