RECENTLY ADDED FEATURE
We have added an optional W-Terminal or TACH pickup wire to this alternator. This option is only available on these “SE” Denso / dodge alternators that eliminate the PCM. When you select this option we will provide a single stator/tach lead for connection to a diesel specific aftermarket tach. This is only available at the time of assembly and older units are not physically eligible for retrofit. We have successfully tested this on various models of tachometers that allow for stator input. The connection is simple, the wire is provided by us but does not need to be used if no tach is intended. This will not work with factory equipped tachometers. (tach shown is not included)

I installed the product about 2 weekes ago and I've been extremely happy so far, no more charging problems, no more woorying about voltage regulators going at the most inconvient times. This altenator is great i recommend it to anyone with a 1st gen
Works perfectly as described. If you need a good alternator for a truck that has charging wiring system problems or simply want one that is simple and reliable, then this is the one for the job!
Best money ever spent had a lot of problems with other this one is worth every penny , couldn’t ask for a better product
Works great. Definitely worth the money
I installed this one wire alternator on my 1st gen Cummins and it solved my charging issues.

Super easy install, strong voltage, great product. Out of five stars this gets six!
This alternator is a apsolut must for any cummins swap project work great steady 14 volts running two 1100cca commercial batteries well down pa performance
Forget about tracking down bad temp sensors or bypassing the PCM with hit-or-miss external regulators. With it's super simple installation and rock solid 14.7 charging volts, this alternator will make your 12 valve Cummins one step closer to "Wasteland Ready"!
