We offer 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 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. 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 or ignition-based tachometers, only a stator signal tachometer. The rotor has 12 poles, some calibration instructions ask this (tach shown is not included)

1 wire pa alternator for 5.9 cummins
After going through endless fusable links I replaced my links to a breaker system but stil had a major problem with voltage regulators and no charge situations for other weak links in mopars wiring program which is very very inferior to several other manufacturers ! after burning through 6 regulators in a few months i converted my old denso to a transpo 1 wire which requires an exciter wire which worked but i wanted to clean my engine bay not add more wires ! with this in mind after personally rebuilding several alternators from slip collar to bearings contact block and adding tach wires to a pickup i determined the easiest most cost effective solution was a PA performance alternator ! they go through everything i would have and probably more id recommend them to anyone needing a superior solution to a problem which mopar refuses to address

2nd one I've purchased
Thank you I'm very happy with my alternator, I sold the other one that i bought from you guys so I could get the one with a tach wire. So far so good I appreciate it.

What a relief
It is so nice to finally have 14 volts all day long. I was constantly replacing voltage regulators in my old dodge. I even installed a relay before the regulator that supplied actual battery voltage. But it never solved it. So I pulled the trigger on this bad ass unit, it’s been 2 weeks and 5,000 miles with zero issue. It just works. Installation was super simple and went right in. I love this alternator. Thanks PA Performance

Best alternator for Fummins conversions
Had this alternator on my 1999 Ford F-250 with a 94 poverty pump 12v worked flawlessly till the hot wire stud stripped out, ordered a new one with the tach wire and it’s been just as good. Waiting on a alternator tach gauge so I’ll have a working tachometer.

Alternator is best
This was awesome I had a huge problem with the charging issue and couldn’t figure it out and this saved me from a huge rat nest of wiring and this worked great!

Works
Original alternator stopped charging but regulator still showed voltage. Read a bunch of stuff online about the regulator in the pcm going out and using an external one but that those need to keep being replaced. So I am saving money by spending money on this Paperformance 1 wire alternator with its lifetime warranty. I never have to worry about paying for a new alternator or the voltage regulator, or getting a expensive pcm. Followed instructions in box and video on paperformance website. Took an hour to install and had voltage immediately on start up. My 12 valve Cummins is now closer to a 1 wire fire thanks to paperformance.
