Question about 1994 Dodge Caravan

1 Answer

I have a 1994 Dodge Caravan V-6 3.0. My check engine light comes on when my Alternator is not working. I tapped the alternator with a hammer and it shut the check engine light off and it was working, charging the battery. Eventually this tapping with a hammer didn't work so I replaced the Alternator AND battery. One year later this is happening AGAIN!! I took the alternator off because it is under waranty and the parts store said I have a good alternator. What's my problem? Is it a wiring problem in the car somewhere? I Just DO NOT KNOW.

Your replacement alternator may be a "workalike" equivalent that overheats and fails under load.

SOURCE: 1994 Dodge colt is having alternator problems I think.

it is a good indication. check the battery with a volt meter a charged battery should read about 12.6 volts dc with the car running you should be getting between 13 and 14 volts at the battery if you are getting 12.6 or under when the car is running you need an alternator.

you should have 14.5 +/- with the AC on you might have a week regulator or week brushes in the Altenator . but not enough at this time to cause a no start . but do have the alt tested (Load tested) at a parts store .

SOURCE: I have a 1990 dodge caravan that will not charge

use a volt meter and check the voltage with the engine off. should be 12 volts then check again with engine running it should be 13 to 15 volts if no then the pcm is at fault. the voltage regulator is inside the computer control and you will need to have it checked out at a dealership. if bad will have to replace the computer on van to correct the charging system. hope this will help!!!

Start out by replacing the oxygen sensors. The electrical system and fuel delivery depend on the O2 sensor to be in perfect condition. If you still have these flashing and flickering lights after you replaced the O2 sensor then then next thing to replace is the ECU (also known as a PCM or vehicle computer) Click on the link below to view the parts you will need:

SOURCE: 1993 Dodge D350 diesel alternator not charging

Hi, I will keep this short, but just a tip on the tester they use, I had one bench tested and it showed up it was good and the built in regulator was good also. Put it in the auto along with a $75 battery, and the discharge light was still on!!. So, I checked all of the charging circuit wiring finding nothing wrong, and put a rebuilt alternator on. Took care of my problem, the alternator was intermittent, sometimes charging when they checked it at Auto-Zone, but stopped putting out when I put it back on the car. I lived 16 miles from the auto store, so it was a pain going back and forth, plus the cost of gas!! I would change it out if you can at this time. I am sure this is what is going on if all looks good under the hood as far as wiring. Check to see if you have the 75 amp alternator fuse under hood also. It may be gone. Make sure the hot cable to the alternator and wiring plug is OK. Change it out and you will be good!
Sincerely,
Shastalaker7

Why is battery not working?


If you don't have the equipment to check the system take it to Auto Zone, etc, and have them check the system. Just because it is a new part doesn't insure it is good. They can also run a check for the codes. Both checks should be without charge.

Check engine light is on


The check engine light could relate to something else - not your battery or alternator.

If your battery isn't charging from the alternator an illuminated battery symbol would appear.

It could be many things - low oil level, low coolant level, low windscreen washer fluid level. It could even be an electronic 'fault' - which a computerised diagnostic check would identify.

If the battery warning light is illuminated the first thing you should do is to check the tension of the alternator belt. You say that a new battery and alternator have been fitted? Take it to an auto electrician - he should identify any fault within minutes.

Battery light comes


If there is no charging voltage with the engine running (you should see more than 13.5 volts at the battery with a volt meter) than the alternator is likely not working. Check to make sure there is power at the large wire at the alternator. If there is than replacing the alternator will likley fix your problem.

Electrical: I have a 2000 Dodge Grand Caravan and the battery light came on . So i hooked up my tester on the alternator and got a low output, than disconnected the negative terminal while the engine


My 2000 Caravan developed this problem after our hard winter so I searched and found that tapping the alternator might reveal that the brushes were intermittent. Sure enough, a slight tap caused the charging voltage to come on at around 14 Volts. A new brush assembly was under $10 on eBay and after finally getting the alternator out and the brushes replaced, re-installed all was well!

1996 dodge caravan 2.4 liter battery light comes on what is the cause ?


Usually a failing alternator. Check voltage at the battery with engine running. Should be at least 14 volts. If less or you don't have a voltmeter, take alternator off and have it tested at the parts chain. Let me know if you need instructions for removing the alternator or have more questions.

When trying to start engine the check engine light comes on and theres a clicking sound.


The battery may be in a low state of charge or you may have poor connections of the battery cables due to local corrosion at the battery. Try placing the battery on slow charge for about 6 hours, then retry starting again. If it seems to work better, you may have alternator problems that fail to keep the battery fully charged. Take the car to your favorite auto parts supplier who can evaluate the performance of the alternator and also check the battery for estimated residual life. Hope this helps!

Need serpentine belt routing diagram for 1994 Dodge grand caravan


3.3L?
Looking at the engine from front (right side of the Van): Stating at the Top, Going Left to Right and Clockwise:
Over the Alternator
To under the Idle Pulley,
To Over the AC Compressor.
To the Left Side of the Water Pump.
To the Right side and Under the Crankshaft Pulley
To the Right side and Over and Down the Tensioner
To Under the Power Steering Pump
And Back up-to the Left side of the Alternator.
Advise when puting it on:
Put the Belt around everything else accept for the Alternator. After it is around all the rest of the Pulleys - Pull the belt up - tight from the Power steering Pump and the Idle Pulley to form a loop, holding the Belt close to the Altenator Pulley.
Using the 15mm wrench or belt tensioner bar - rotate the Tensioner Pulley towards the front of the Van and then place the belt over the Alternator.
Let me know if this helped or if you have additional information or questions. Feel free to contact me at FixYa.com!
