What should the voltage be on a Dodge Ram 3500?
What should the voltage be on a Dodge Ram 3500?
I tested the battery and it was 11.75v then started the truck and it was still 11.5v. (note battery was low because i got done driving). So I took off the alternator and went to a local auto store and got it tested and resulted as “good” scoring at 15.37 volts. Dropped it back in, still same scores when engine is off or on.
What does a low voltmeter reading on a Dodge mean?
Another low reading would mean that your battery is bad or that you have a short circuit in the wiring. Disconnect the voltmeter from the battery posts and ask a friend or family member to get behind the wheel and start the Dodge. Then reconnect the voltmeter to the battery exactly as you did before.
What should the battery reading be on a Dodge?
A reading around 12.5 or 12.8 volts is normal. A reading below 12 volts may indicate your Dodge’s battery is the culprit. Charge the battery and, without running the car in the meantime, test it again the next day. Another low reading would mean that your battery is bad or that you have a short circuit in the wiring.
Why is my voltage regulator working on my Ram 3500?
Anyways so my voltage regulator started to work, it scored around 16-17 volts and i figured the battery’s was dead and the alternator was charging it by giving a lot of juice. Well i took it on a 40 minute drive, came home and smelled something funny and stinky.
What should the voltage be on a 2003 Dakota Durango?
Most, not all electrical gremlins are due to bad GROUNDS. Did you ever resolve this issue? My 2003 Dakota does the same thing, even after the meter goes to zero the voltage at battery when running is under spec at 13.8 to 14.2 ish, including when under a load.
Where is the check gauge on a Dakota Durango?
In case anyone reads this in the future, when you start your Dakota/Durango and the Vehicle Starts, Voltage Guage goes up to 10-11 Volts then drops down to 0 and “check gauges” light comes on, your first check is the Big Fuse located in the ECM (engine Control Module). Usually 120-140 or 160 depending on your alternator.
Why does the dash gauge switch from battery to alternator?
OK now that is starting to make sense. If the dash gauge switches over from reading battery voltage to alternator voltage after the engine starts, and there’s a diode between the alt. output and the battery, it would explain a lot. I will take readings at the alternator and let you know what I find.
Why does the Volt gauge drop all the way down?
Lesson learned, volt gauge on the dashboard dropping all the way down likely means alternator. Funny thing is it’s probably set up that way in the ECM to warn the average (clueless) person of something wrong.
How does an alternator charge in a Dodge Ram?
Battery positive, a ground wire, and two additional wires either in a connector or as two ring connectors in your case. Of those two outlined in red, one runs to the PCM for charging voltage control, there is no real voltage regulation occurring in the alternator itself, it is controlled from the PCM.
What kind of battery does a Dodge 3500 have?
Had a concerning question about my 1998 Dodge Ram 3500 12 valve 5.9 turbo diesel 4×4 manual. My alternator wasn’t working. I tested the battery and it was 11.75v then started the truck and it was still 11.5v. (note battery was low because i got done driving).
Is the voltage regulator on the Dodge Ram 3500 5.9?
Hey man so on the 2003 Dodge Ram 3500 5.9 the voltage regulator is in the ecm 100% I was told it’s not on those year models. Having the same issue been down for week waiting on shops. Passenger side battery over heating and truck won’t stay charged. Click to expand…

How many volts does a Dodge Ram have?
Reading 15.2 without a load and 15.8 to 16 with a load but never goes any higher. It may be coincidence but it seems like it started right after I had the intake manifold off doing the plenum plate upgrade.
Why is my alternator charging at 15 volts?
The charging voltage is controlled by the PCM. It is likely not a coincidence that this happened right after removing it to access the intake. You should have not just a positive charging lead, but also a second two pin sense and excitation plug on the back of the alternator. Make sure this plug is in and secure.
