If you have any conserns with the alternator, I would replace it. When you had it tested was the problem existing if not, the test would not be acurate.

Code 124145


The 12 is normal for the starting code. The 41 says generator (alternator) field is not switching properly. Code 45 says Turbo boost limit exceeded (engine was shut down by logic module). I doubt that you have turbo on the Dakota. However there IS a code 46. Battery voltage too high during charging or charging system voltage too low. That would make sense with the 41 code. Sounds like you may have an alternator/charging system problem.

Ford v10 triton engine alternator won't charge brand new


I had a similar problem on my 98 Tioga (Ford v10). Turnd out to be just a blown fuse in the cab (wich controls the alternator's regulator.) First, confirm its the charging system and not the battery it's self. To do this, start the engine and take a voltage reading at the battery. It should be above 13 volts. If you don't have a tester, with the engine running, disconnect a battery terminal. If the engine stalls, it's proff the alternator is not out putting as it should. Check for a blown or missing fuse. Anything labeled "intrusment cluster" or "Alt" (maybe 14). If the fuses are ok you'll likely need to replace the alternator it's self. On those engines it's not hard to do. Only takes about 20 min and the the alternators are around $130. But defiantly check the fuses first.

The battery is lossing power in the battery and when i hit the breaks the battery light comes on


Sir. lets figure what is happening to fixing it
Your car`s battery is loosing it`s charge because it is not charged in proper manners thinking why ? Simply what charges the battery is the alternator after the car is running it the engine drive the alternator ant different speeds when alternator is revving faster with faster engine revs it produce lots of electric that the battery may don`t need and could harm the battery
when revving low the alternator my generate less than 12 voltage
the alternator is need something called the Regulators witch as name suggests regulates the voltage generated adjust it to constant limit that the car needs to work fine
alternator belt and pulley
have a good day Sir .
we are happy helping you any time

Have 2002 Nissan frontier. Recently bought new battery. Had alternator checked by autozone. Truck will not start occasionally, and sometimes dies while driving. Lights will dim and truck will not...


I would get a second opinion on your alternator. Does your battery light come on while your driving? That can be an indicator of an alternator going bad. Also, there's an easy way to check the alternator yourself if you have access to a multi-meter. Turn the multi-meter on to DC volts and start the car. Put the positive lead on the positive battery terminal and the negative lead on the negative battery cable. While the car is idling, the meter should read 12.5 - 13.5 volts. Have someone rev the engine. With the increased RPM's the meter should read over 14 volts. If the voltage goes down when you rev the engine, your alternator is bad.

Good Luck!

Charging system not working. Major problem with the 1991 Dodge Dakota 5.2L 4x4 Sport charging system not working, major drain on the battery. Searched for short. Any ideas? Already replaced alt. and...


Check output from alternator with a voltmeter it should be between 13.8 to 14.7 if so then check at battery if it is not at least 13.8 minimum to be charging then the big wire on back of alternator is not getting back to the battery through ammeter gauge in dash.
I have hooked a wire from back of alternator straight to the plus[+] side of battery to fix that issue.
Sometimes ammeter gauge burns out breaking the circuit from the alternator back to the battery.

ALTERNATOR REPLACED WORKING OK NOW TIMING BELT PETROL AND BATTERY WARNING LIGHTS ON WHEN ENGINE RUNNING AND A/CON NOT WORKING


If your battery warning light is on, then your alternator is NOT working okay. Rather, maybe the alternator DOES work, but the battery light can also come on if your battery won't charge.

Put a voltmeter to the battery terminals when the engine is running and rev the engine to a medium idle. Battery charging, (engine running) it should be about 13.5-14.5 volts. Engine off fully charged battery voltage should be 12.6 volts.

Quick test-engine running, disconnect the positive battery terminal from the battery- if the engine dies, there is still an alternator problem.

Hope this helps.

Could be battery. The starter takes a lot more amps than the lights or radio. You should get a jump to start the truck. Then drive to your nearest chain auto parts store. Most of them will do free battery and charging system checks. You could also try disconnecting the positve ( red) terminal of the battery after you get it running. If the engine dies your alternantor is bad. You should also get your battery checked if your alterator is bad. Sometimes a bad alternator damages the battery.
