Choosing the Right Aftermarket Alternator for Your 1995-1998 Dodge B3500
Keep your B3500's electrical system running strong by understanding its unique charging system and picking the right replacement alternator.
- The voltage regulator is in the PCM (computer), not the alternator; a new alternator may not fix a charging problem if the PCM is faulty.
- For stock vans, a premium aftermarket brand like Bosch or ACDelco is a reliable choice.
- If you have added electrical accessories (camper parts, extra lights), upgrade to a high-output alternator from a brand like Powermaster.
- Before replacing, verify the alternator is the problem. Test battery voltage with the engine running; it should be between 13.5 and 14.5 volts.
Is Your Alternator Failing?
The charging system on this generation of Dodge van can be tricky to diagnose because a bad computer (PCM) can act like a bad alternator. However, if your alternator itself is failing, you'll likely see one or more of these classic symptoms.
PCM-Controlled Voltage Regulator
A critical point for 1995-1998 models is that the voltage regulator is not inside the alternator; it's part of the main computer (PCM). If you replace the alternator and still have charging problems, the issue could be the PCM itself or the wiring between them. Common trouble codes like P0622, P1594, or P1682 point to a fault in this control circuit.
Choosing the Right Aftermarket Alternator
With original Mopar parts being scarce, a new aftermarket alternator is the go-to choice. The quality can range from basic replacements to high-performance units. Your choice depends on your van's electrical needs and your budget.
Tier 1: Premium Aftermarket
Brands: Bosch, ACDelco, Remy
These brands are well-regarded for their reliability and are often recommended on automotive forums. They are built to meet or exceed original specifications and are an excellent choice for a daily driver or work van where reliability is key. While they cost more than budget options, they generally offer better longevity and performance.
Tier 2: High-Output & Performance
Brands: Powermaster
If your B3500 is a conversion van, a work truck with extra lights and tools, or has a powerful stereo system, a high-output alternator is a smart upgrade. Powermaster specializes in units that produce more amperage, especially at idle, to handle the extra electrical load. While they are a great solution for heavy-duty needs, some owners have reported bearing noise or failure over time.
Tier 3: Standard & Value Options
Brands: WAI Global, BBB Industries, MPA, Skyward
These brands offer a budget-friendly way to get your van back on the road. WAI Global units are often 100% new and may come with an individual test report, but some users have reported long-term durability issues. Brands like BBB and MPA provide functional, standard replacements that meet basic requirements but may not have the same lifespan as premium brands.
Alternator Cost Overview for 1995-1998 Dodge B3500
| Part Type | Estimated Price Range | Notes |

| Shop Labor | $120 - $250 | Expect 1 to 2 hours for professional installation. |
Pro Tip: Check Your Pulley
When you buy a replacement alternator, compare the pulley on the new unit to your old one. Some aftermarket parts may come with a serpentine belt pulley, while your van might use V-belts. You may need to swap the pulley from your old alternator onto the new one, which can be done with an impact wrench and a vise.
Frequently Asked Questions (FAQ)
Can I replace the alternator myself?
Yes, this is a DIY-friendly job for someone with basic tools. The process involves disconnecting the battery, removing the drive belt, unplugging the two electrical connectors, and removing the mounting bolts. Access is generally good from the front of the engine bay.
What amperage alternator do I need?
For a stock B3500, a standard replacement alternator with 90 to 136 amps is usually sufficient. If you have added significant electrical accessories like a winch, extra lighting, a large stereo amplifier, or camper equipment, you should upgrade to a high-output alternator (160 amps or more) to prevent issues like dimming lights and to keep the battery properly charged.
Why are my lights still dim after replacing the alternator?
If a new alternator doesn't fix your charging problem, the issue likely lies elsewhere. On these vans, the voltage regulator inside the PCM is a common culprit. You should also check for a blown 120 or 140-amp mega fuse in the under-hood fuse box, poor wiring, or bad ground connections, as these can all prevent the system from charging correctly.
Are there any recalls for my van's alternator?
No. While Chrysler issued a major alternator recall (NHTSA 17V-435) for potential stalling or fire, it only applies to much newer 2011-2014 models and does NOT affect the 1995-1998 Dodge B3500. There was a recall for the ignition switch on 1994-1996 models that could overheat, but it is a separate issue from the alternator itself.
Technical Specifications
OEM Part Numbers: 56041394AA 56027913
Standard amperage ratings for this vehicle typically range from 90A to 136A. The charging system uses an external voltage regulator located within the Powertrain Control Module (PCM). The alternator uses a two-pin field wire connector and a B+ output stud.
