ERCK - External Regulator Conversion Kit

It works

Installed on a 99 ram 2500 cummins. It works so far . Working for about 10 days now. I turned it down so the needle on my dash was lined up with 14 volts. It's now charging at 13.6. Instead of 14.1. Easy install and it works.

The pcm internal voltage regulator failed in my truck and it was overcharging this kit got me back on the road again it wasn't hard to install either
