This procedure usually works:
·Check the battery cable connections:
Make sure the negative cable makes a good ground connection at the battery and (preferably) at the engine. Make sure the positive cable, makes a good connection at the battery and at the starter.

·Check the battery the simple way, like this:
Turn on the headlights, then try to start the car.If the headlights do not dim or go out, then the battery is likely ok.

·Check the starter and solenoid:
If the wiring looks ok, then look at the starter solenoid for a good connection, and proper voltage at the starter(10 volts minimum while cranking).
If the starter spins and no crank, the problem is most likely the Solenoid's pinion gear is stuck.
Have someone hit (not too hard) the starter while you try to start the car. This usually works by dislodging a stuck pinion gear.
·Make a simple test of the alternator:
If you can, somehow get the engine running, measure the voltage at the battery. It should be at least 13.6 volts to properly charge the battery.

Howdy in addition tho your first answer check both of your battery cables. If you suspect even the slightest replace em. That year Bronc was cool had one. Got 9 miles a gallon but easy to work on. Getting spark plug 8 was a beast. Good luck.

check for a blown fuse,sometimes if the battery cable is connected when changing an alternator it overloads the fuse,also check for power at any fusible links

Hi, have you checked continuity of the charge wire? There are fusible links there that may have burned up.

My 1998 dodge stratus needs to be jump started everyday, what could be the problem

Need to get a meter on that car,auto zone will do it,make sure it's charging.
I am thinking the voltage regulator is not in the alternator.Think it's in the control computer. If it goes bad ,the car won't charge.Instead of buying a computer you can also use an older style (say 1980's) external electronic regulator.have to get a pigtail from a parts store ,hook up 2 wires to the alt. Cap and seal the old wires that used to go to the ECM. Works fine and won't go bad again.

I have installed 4 reman alt on 1993 gmc suburban still will not charge. the first 3 alt were from small local parts store(cheap) so i took one into a pep boys store in tulsa they tested it and it would...

Sorry to hear about this Dale but I don't believe you have done anything incorrectly. Use your DVOM with key on to check for 12v at the pigtail wire.The main cable should always have 12v but the pigtail should have 12 volts with the key on and or running safer to check with just the key on.Check this out and we can proceed with further instructions.

Alternator test said good, put on car & not charging ,battery test good amp meter decrease`s

Remove and clean battery cables , replace bolts. Check for power going to the alt. it will not charge unless is has power in the connector wire. When alt is tested get them to tell you how many amps it is putting out, not volts. 12 volts will not charge a battery unless you have the correct amount of amps. I had a napa alt and had this trouble twice. The guy said it was good it had over 12 volts output, but it would not charge battery. I fixed mine with a better quality alt. from another store.

Charging problem, alternator is new

it does not have a relay on the post on the altenator should have battery voltage and with key on should have voltage on the wire in the pigtail with it unplugged if you have that the alt is bad
