When you pluged the connections in reverse,did you here a pop?if you did ,look for a blown fuseable link in the wiring under the hood! Check all the fuses in the interior of the car under the dash ,under kick panels,where ever there is a fuse block. check for power to the fuses on one side to see if supply circuits are ok.you may have more blown fuseable links or burnt wiring.with ignition sw on. you may also have bad regulator and rectifiers in the alternator.Check all pigtails off the positive battery cable for blown fuse links.or any wiring coming from starter relay,solenoid. .

It is a pretty good bet that you fried a number of components, however there is more than one fuse block. Look under the dash. There is also a box that has relays and circuit breakers. Test these too.

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.

2007 ford f150 will not start. IGNITION DOES NOT BUZZ WITH KEY IN, GEAR WILL NOT SHIFT. LIGHTS WILL TURN ON. THE STARTER HAS BEEN DRAGGING. DOES NOT CLICK WHEN I TURN THE KEY. WHAT COULD MY PROBLEM BE


Pull off the neg and use jumper cables connected to another vehicles battery. Attach the jumper normally on the other vehicle, attach the Pos to your battery pos and then attach the neg jumper cable to the disconnected neg cable on your truck. My suspicion is that your battery may test well with a volt meter but cannot take any load on it. It should be floating at 13.5 to 13.8, not 12vdc.

How do you wire up 4 6 volt batteries in a 1976 kenworth. 12 volt lights 24 volt starter


When you go pos to neg from one battery to the next it increases voltage, pos to pos just increases amperage. You would want to wire 2 in series, just imagine stacking batteries in a flash light, pos from one to neg on next. Remaining pos and neg are 12v now. Run both remaining pos to starter and ground both negs. your pushing a lot of amps with the batteries and doing 12v, and your charging system is 12v. If you do another series from there, you have to regulate the voltage when the starter kicks in...you risk burning every light and electric component...just like running 12v in 6v system... You can also use 4 12v batteries and run all pos to pos and all neg to neg and have mega cranking amps...that is how all modern big trucks are set up. Your pushing around 7k cranking amps that way(1500 per battery)...plenty to start the healthiest cat... And don't have the worry of dual voltages or running in series. You really don't need 24v to start and unless you have a 24v alternator, these are your 2 options. Best bet if your not sure is to try with 12v...no risk of frying anything even on 24v system. 24v on 12v system is, on the other hand, a big risk. 43bf17ec-4e37-4a15-a147-d1e7a1377d9f.jpg

Had the alt replaced on my 98 etc in march. Last month the battery not charging light came on and the car died. Bad alt or more serious problem


If you have access to a multimeter start the car put the meter on range 20v dc or if it's an auto range meter just put it on DC and while the car is running put the meter at the battery pos to pos and neg to neg . it should read between 14 - 14.5 v if it's not the alternator is not charging the battery. If it reads OVER 14.5 It is cooking your battery. I have 2 Cadillacs myself and the rebuilt alternators you get are horrible i replace 2 a year cause the rebuilds are crappy. I used to rebuild them myself but the kits are no longer available.

How do I check an altenator


You need a DVOM or digital volt ohm meter hook the neg to neg on the battery the pos lead to pos on the battery set scale to dc volts 30.Start the car and read the meter it should be at 13.5 to 14.5 volts if not alt is not working.You can also take it to autozone or kragen and they should check it for you free.

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.

Battery will dran over a short time and is the second new battery


The best way I have found to hunt down a current draw is with a multi meter set to the DCA setting (this will detect DC current flow). With the vehicle shut off, systematically remove fuses one at a time and place the leads from the meter in the connectors that held the fuse (one lead per fuse connection). You should have a little current flowing to the radio, for the clock, and maybe some to the engine computer and, if equipped, the alarm, the rest of the circuits should have no draw. This will narrow down your search to one circuit in the car, which can than be further diagnosed, usually it's a wire with the insulation rubbed through.
P.S. if the car has any after market equipment, such as audio amplifiers, start your search there. Hope this helps, good luck!!!!

There is a problem with a wire harness and it continues to drain the battery. How do i find it?


you will need a volt meter for this!
first remove the neg. clamp of your battery..
connect the pos.[red]of your volt meter to
the neg.camble and the [black] neg wire of the
volt meter to the neg. post of the battery.
if there is a draw it will show on your meter.
if thats the case start pulling your fuses one at the time until you find the circuit thats killing your battery
