Why would a 96 Chevy cavalier that has just had the alternator changed not turn over the battery checks good?
Have them check the PCM on the car. I JUST had this problem with my 99 Cavalier and the mechanic had to pull everything out of my dash before he found that my PCM was fried somehow. Just so you have symptoms to compare to, my dome light and dash indicators would all light up and work fine, but when you would try to start the car it would not even click. It acted like my battery was dead. I had to jump start my car every time I got in.
What else can I help you with?
Why does the battery light come on intermittently the alternator has been changed battery checks good the lights flicker when battery light is on and light goes out after car is restarted?
Battery light usually means alternator not charging. Most common solutions would be be a bad alternator, bad connection, or loose alt belt.
Why is my 1984 alternator charging constant 16.3 volts?
If the battery checks out okay, you can replace just the voltage regulator inside the alternator.
1994 Mercury Grand Marquis. The battery light stays on and causes a drain It goes out when the ignition is off Any ideas Difficult to start and stalls. Changed alternator and battery checks ok. Help?
The battery light isn't an indicator that the battery is always bad. What the light should really be is a picture of an alternator, but most people wouldn't recognize that. Have the alternator checked off the vehicle to make sure it is good, then have it checked on the vehicle, (many places like Auto Zone do this for free). If it's not charging on the vehicle, you could have an alternator fuse bad or your car might even have an inline fuse between the alternator and battery. Many Ford products have a large fusible link between the alternator and battery, and if it's bad, there is no power going to the battery from the alternator. Good Luck!!!!
Why won't a 1998 ford contour start after the battery is replaced and alternator checks out good?
u might need a new starter
Have a 1994 ford probe that is not charging and the Alternator checks out good What else could it be?
If your 1994 Ford Probe's alternator checks out good but the battery isn't charging, consider inspecting the battery connections for corrosion or looseness, as poor connections can prevent proper charging. Additionally, check the wiring and fuses related to the charging system for any damage or breaks. Lastly, a faulty battery can also be the culprit, so testing the battery's health is essential.
Why does your battery die and car cut off when its hot and you have the ac on in summer time?
Because the ac uses juice from the battery, if it uses all the energy, the car wont start Just as in winter, when you have the heating on, the AC uses the heating fan to circulate the cold air. It is the fan that takes the current from the battery and if the battery is not holding it's charge or the alternator is not charging the battery then the battery will die and the car cut out. It this situation it is best if 2 checks made, if necessary, by an Auto-Electrician. They are:- 1) The battery to see if it is holding it's charge and 2) The alternator to see if it is charging. Replace the faulty components. If the car cut's out when the battery dies this suggests the alternator may well be at fault. However the checks will confirm this one way or the other. A red light may show on the dash if the alternator is not charging.
Why would a new battery drain when nothing appears to be left on and the alternator checks out ok?
For a battery to "Drain" you MUST have a short somewhere or the "Glovebox" or "Trunk" light is staying on etc. etc. Battery's don't just "Drain" on there own ;-) TommyTrouble
What two external checks that should be carried out when inspecting an alternator for charging faults?
When inspecting an alternator for charging faults, two essential external checks include verifying the battery voltage and examining the connections. First, measure the battery voltage to ensure it's within the normal range (typically 12.6 to 12.8 volts for a fully charged battery). Second, inspect the wiring and connectors for signs of corrosion, loose connections, or damage, as these issues can hinder proper charging.
Shut car off and most of the time the battery goes dead and have to boost the battery.But battery checks out as good?
Make sure the battery is checked out under a load. This will indicate whether the battery is capable of holding a charge.Second, suspect the alternator is not charging the battery.Third, suspect a short or a switch somewhere that is draining the battery.
Why is it important to perform a load test on your alternator?
It checks many things, connections, belt, and voltage regulator. I have never checked one with a load test. On a modern car or truck, never ever disconnect the battery from the alternator with the motor running to check the alternator. It can burnup a lot of electronics instantly.
1996 camaro 3800 was not charging you changed the battery the alt and the belt now the voltmeter in the car fluctuates wildly from half to max and the check gages light comes on?
Sounds like something might be hooked up wrong. Check alternator wires and battery cables for good/correct connections. Check for any shorting wires (maybe something got pinched when you put the alt. in) around alt. If all checks out, maybe you got a bad alternator.
Why would my truck not recharge the battery i have a f150 1985 i want to think its the alternator i stalled it twice and it drained the battery... i replaced the battery on 5 days ago too?
I had this problem on a 1979 Mercury Grand Marquis- it turned out to be a short in the wire going from the alternator to the battery. It was intermittent, so it was very hard to run down. If the alternator checks good, the short/broken wire could easily be the culprit.Rocky_B - See my entry here for more things you might want to check: http://wiki.answers.com/Q/What_could_be_wrong_if_the_battery_light_stays_on_and_the_battery_still_runs_down_on_a_1996_windstar_after_installing_a_new_battery_and_alternator
