No it is most likely the alternator that is defective, GM trucks seldom have any wiring problems

96 fordexplorer i put new battery and altenater but still not charging


On the alternator there is a heavy red cable (wire) going to the battery. The battery gets charged though that wire. There is a fuse in that wire between the alt and batt. That fuse is called a fusible link. Check the voltage on that wire at the alternator. You should have baytery voltage there. If you have no voltage, the fusible link is burned out.

Charging system diagrams for 2002 dodge dakota


There is 4 gauge black/red wire going from te alternator to Fuse #2 in the PDC. The alternator and battery both connect (positive side) at this point. The alternator's path to charge the battery is from the alternator, to this tie point, then to the battery. In the wire, between the alternator and the PDC tie point, is a fusible link. This link may have broken or melted. That would keep the alternator from being able to charge the battery. I would check this wire for continuity and replace the link if necessary.

My 2007 dodge 1500 alternator won't charge


Check the battery condition as low battery will not induce the alternator to work. Check belt tension and condition. Place a multi meter in the battery to alternator wire and check for dc and ac current and if you have ac then the rectifier diodes in the alternator have failed.

New battery , wires and plugs and still have trouble starting in the mornings, get a jump and starts. After running vehicle for awhile I turn it off and try starting it it will start.


check alternator output with engine running.you should have 13.5 - 14.5 volts if not alternator not charging.check alternator wiring to battery feed to alternator.check alternator voltage regulator wiring check alternator fuse make drive belt not slipping.and you have the correct cold cranking amp battery.bad old worn out battery cables will cause charging problems.because old battery cables put high resistance on the charging circuit.if battery cables old as vechicle replace them.

New battery. abs, battery and service engine lights come on. all headlights and tails flicker and car dies and wont start. jump it let it warm up and doesnt do it for awhile. then at some point it does it...


These are all signs of a bad alternator. The car is running off of only the battery. The alternator charges the battery and keeps the car running. When the alternator quits charging the car will run fine until the battery dies. Then you can jump the battery and charge it, and the car will run fine until all of the electronics and lights run the battery down again.

The main wire from the alternator to the battery is not making connection,just run another one to the positive side of the battery,to the large wire on the alternator,leave the other one on the alternator,just add this one,use as big of wire,or larger,a small cable will do nicely.
