Check the large probably 100 amp fuse under the PDC cover. Is this a 12 valve or 24 valve engine? If it's a 12 valve, it may be a bad crank sensor. It tells the PCM to turn on the ASD relay which supplies power to the alternator field.

98 chevy malibu my alt isnt charging new alt batt test good cut out the fuselink on starter the alt wire runs thru firewall If i run a wire straight to the batt it is putting out 19v any suggestions


Did you check the fuse in the under hood fuse box ? GEN / BATT fuse 10amp . Is your check engine light on ? This is a computer controlled charging system , it should have four wires connected to the alternator . 1 - the heavier wire on the back ,this comes fro the starter - the one with fusible link , you could have checked for battery voltage with voltmeter ! The three other wires in the connector are the orange one ,this comes from the GEN / BATT fuse an should have battery voltage ! The last two come from the PCM - engine computer . The gray wire is the turn on signal from the PCM an the Red wire is the control from PCM ! Charging System Wiring Diagram MOTOR Magazine Article MOTOR Information Systems

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.


brakes:
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.

I just put a new alternator on my 97 isuzu rodeo but it still draining the battery and stalling how do I reset the computer so it picks up the new alternator of is it something else


i bet you skipped step 1, in the book, FSM and all car repair books in print, 100 years now.
disconnect the battery neg lug first.!
oops, you blew the main fuses. (or blew up the new alt... sad huh)
cb 7 or cb3 fuses blown? CB means cab fuse.(dash box)
drains driving, i bet.
right.?
and the battery is not 13.3v to 15vdc running (good range)
bet 2:
and engine RPM is 800RPM or more at all times, right?
not 400.
the belt is not slipping or missing.
the connections are all tight
the battery cable lugs, are all clean, x4 ends. right?

no engine stated, size and number of cylinders.
as you may not know, diffr, engines sometimes have diffr ALT.
usa answer (for just 2 engines only , usa)
2.6L and 3.2 liter both have PCM generator gain control pin
and the PCM can be bad.
is the charge light glowing running, ?????

here is the proof the PCM does run the reg inside ALT.
called gen gain line.

25782645-zy5i2xuw3mfjw4tca3plar50-1-0.jpg you didnt blow EB17 main fuse that kills all .
there is the CB fuse , for alt.

How do i fix my voltage regulator 98 dodge ram 5.2 new battery new pcm?


Voltage regulator is internal to the Alternator. You have to replace the Alternator.

Why do i lose voltage intermittently from the alternator when i step on the brake ?


what engine size?
the PCM runs the show, and its bad. or wires bad to it.
your car has PCM regulator.
no charge battery light.?

1: takes a good battery and battery cables and lugs cleaned.
2: test the altenator, odd how 4 of yours all tested good but you replaced it 4 times, get it tested if good, its good.
3: then check that the charge .battery lamp works. if the lamp works
that means the PCM thinks that charge system is bad.
if the wires from the rear of the alt, to the battery red and Gy wires
are good all the way to PCM then the PCM is bad.
the big wire on rear of ALT , on one car had a bad lug. #6 wire.
he replaced the ALT 6 times. all wasted effort.
inspect the wiring first. that is free, and is simple fix.
and if the ALT casing is not grounded, all bets off.
same with battery minus lug not good, on BOTH ENDS>
one guy had his battery lug moved to frame, (wrong)
and this never worked.

I have a 2000 dodge stratus. Battery light was on for two weeks then the gages and radio started to twitch we tested both battery and alternator both have been changed we took it for a test drive...


ok that is NOT a battery light, its a CHARGE light!
it comes on and means the battery is not CHARGING.
(the pcm knows this for a fact, in fact IT turned the lamp on.... a key fact.)
any shop can measure the voltage and tell you that in 5 min flat.
he'd
  1. open hood, measure battery, ah, 11vdc. so he jumper starts engine. it starts (cables removed now)
  2. the meter back to battery terms, and its not 13.3 to 15vdc.
  3. he saw 11v. running. oops. that is WRONG.
  4. so he now knows the alternator is bad, or the alternator hates the battery,(can happen)
  5. on ours we can hot wire the alternator to see it go full on, this is called FULL FIELDING and ALT, i dont teach you that, because you will hurt yourself or car.
  6. The PCM on many cars runs the alternator, in fact there is on inside alt, regulator the PCM does that. so can be bad.
  7. if you had before tested your old battery it would have passed.
  8. if you had tested the old alternate (free in any auto store) it too would have passed, (now they are new) so that leaves wires and and last PCM bad.
  9. your pcm pin C1-8 conrols ALT pin 2. field . at all times.
  10. that wire is dark green.
  11. the alternator is very tricky here( pcm brain side) it will drop the battery charging off line if the battery cables are bad. or any wires related to battery cables, grounds or bad wiring on rear of ALT.
  12. the Same is true if the PCM thinks the battery is shorted or open or has insane internal high resistance. (bad batteries)
  13. for current overload, and for OVER VOLTAGE.
  14. that is about it. there is more, but that is all covered in you missing FSM.

Charging system voltage low


there are only 3 parts. but the causes are 25 or more.
1: belt missing slipping,
2: engine rpm below 800 RPM (lots of ways ,ask )
3: ALT had.
4: wiring to ALT bad.
5: bad battery or its connections, (wires)
6: bad fuse. see fuse link a11? on fFM page 20?
7: car is PCM alt controlled, it can be bad too. see 2 field wires on ALT and PCM on page 20? below?
8: battery temp sensor bad. making PCM think battery overheats.
the fSM covers all tests above.

pick car here, then pick charging.

Not able to communicate with PCM with diagnostic scanner


did you really check all fuses. (using an ohmmeter)
what engine, I4 or V6?????
are you posting to someone elses PCM Com problem or what?
is this just and alternator issue , how confusing can this be....
PCM> coms. fails.
3 possible.
1: pin 16 in the OBD2 conn, is not 12vdc. blown fuse. (use a voltmeter)
2: wrong scan tool old tool , on modern CAN buss car will fail. 100%
dead. (open SCAN tool book read if it supports CAN buss)
3: Dead PCM or id bet its , a fuse blown to it.

now i do ALT.
18v is bad. (using a quality DMM or radio shack 1960 meter?)
it means the ALT regulator OUT of CONTROL. ( or bad wiring to it)
changed what?, alt is new, used, rebuilt, barrowed? what.?
This car , im looking it up now, at alldata.com so could you,
or the FSM.

this ALT has a regulator, but is just a slave to the PCM.
in that the PCM controls the REG with 3 wires.
the diagnosis is not easy , i recommend, the FSM
it covers all steps., in the diagnosis,

top fail reasons.
1: bad fuses.
2: bad wiring and connections. (see schematic)
3: bad battery (not you) (open cells cause REG to shut down. )
4: bad ALT. (i say a fella change alt 5 times, and skipped #2)
5: bad PCM. (last, , show me that tests, in FSM)

all that and tons more in the FSM. read it.


or log in to alldata.com and read the Charging pages.
