SOURCE: Battery completely dead within 1-2 hours

Disconnect the negative side of the battery. Hook a volt meter on the negative cable end, and hook the positive end of volt meter on the negative post of battery See what it reads. If it reads 12 volts, pull fuses one by one, and replace until the volt meter drops down. Whatever fuse you pull, and the voltage drops down to 2 volts, that is where the problem lies.

SOURCE: elec problem between alternator and battery

The Problem was that the plug-in that goes into the altenator was not getting a good conection. Drove the van after that I had it fixed and the battery light came back on and I checked the altenator and the plug-in had fallen completly off. Plugged it back in and made sure that it snapped in completly and now it is fine.

SOURCE: Low voltage out of replaced alternator

Possible to have bought a bad alternator.... Try another one..Take advantage of the warranty the bad one came with....But have them check the voltage output on the new one so you KNOW for sure....Also consider issues with your voltage regulator and the possibility of needing a replacement. They are relatively inexpensive so that is the good news....More serious issue that could be addressed is a short somewhere in the harness. I would recommend a full electrical diagnostic to make sure there is not a bad ground....If you'd rather not spend a lot, just check all the wires you can visually.....But keep in mind that the voltage regulator is key and you do not want to spike the computer with inconsistent power levels and surges.

SOURCE: New alternator wont hold a charge is there a

If you have a fuse it will be in the power distribution center near the battery main fuses and relays are inside.
Check the charging system with a volt meter right at the battery. Battery standing charge should be no lower than 12v if charging you should read between 13 and 14 volts running, about 13 with all electricals turned on. If not, the alternator isn't working OR the regulator has failed. (some regulators are part of the main computer but you need to check which system you have. AND do check for fuses.
If charging system is working you may have a system draw that is pulling the system down overnight. Check that with an ammeter between either cable (removed from battery) and battery connection...pull fuses one by one till draw disappears then check components in that system. Don't be concerned with "low Draw" items such as radio that always pulls something to keep memory and clock working.

1999 3.2l. Why are battery and brake lights on?

was not on before the new alt,? is alt new or used.?
or came on only after the new ALT?????????
my guess, is 2 failures.! (one ignored and 2nd grew)
on with engine running, guess yes.
Good question and is same answer on all cars.
1: engine rpm too low, what is yours (below 80 rpm)
2: fan belt slips. bad tension pulley (weak and old???)
3: Alt bad, or its wires bad.
4: brake level low, (@MC) or hand brake switch stuck on, or other brake failures. a plenty, scan the PCM and ABS if you have ABS.
id not drive it with the brake lamp on (Savvy?)
the battery light is really the ALT charge lamp.
it glows anytime the Charge system can not charge the battery
if you drive far like that, the engine will stall and not crank.

5: the horn fuse power the alternator, so check the horn fuse
10amp , key on, 12vdc on both sides of fuse is needed/
fyi: the meter fuse runs the charge lamp, if said lamp is dead bingo.
6: fact 2, the PCM does NOT run the Alternator on the 3.2L .
7: alternator case not grounded right.
8: battery is bad, causing alternator to drop off line
9: battery cables bad, at the 4ends or they are bad.
10: the plug on the rear of alt is bad or its wires or pins rusty.

the brake lamp has 3 inputs ("OR" logic) master cylinder level low.
the hand brake lever and the EBCM (electronic brake control module)
a technician unplugs each to see what causes the error.
if you unplug mC wire and hand brake wire
then the EBCM is UNHAPPY, scan it.

New battery not charging after changing the alternator

First make sure both battery cables are free of corrosion and ground is secured to chassis and engine then check to see if theres an alt. fuse or bat. fuse blown. Another way to test charging sys w\out an meter is to remove the ground terminal from the bat. with the car running, if the alt. is good car stays running, if all else fails take the alt and bat to a parts store that will test them for free

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.

sounds like the voltage regulator on the altenator cable or the cable running from battery to altenator shorting a bit.

96 cougar v8. new alternator, new battery. we worked on it all day at autozone. got a new battery and alternator. when we started it up and tested it it would go to 12.6v then fail. we tested the...

I had the same problem on my 96'. It ended up being the mega-fuse, which is located on the left side of the fuse box under a plastic cover that slides up. It has two wires running to it(one of which is the main wire from the alt to the battery), and two bolts holding it in. Hope this helps.
