Description

This is a universal voltage knob to replace diodes on internally regulated alternators with S or Sense Pins. The peak voltage will vary on manufacturer of the alternator you have.

Rating is based off the 14.8v pcm bypass regulator we sell and install in the denso based alternators we build. Some manufacturers will see 15.2-4v peak with a 14v-14.2v set point. With a 14.8v set point from us you’ll see 16v max.

You will wire these to S, and then to a relay off ignition in the fuse box with a 5a fuse inline. 

There will be no individual instructions with the unit as every vehicle is different. Just generalized instructions to guide you through install. 

This is for people intending to charge higher than stock, this is not a plug and play install there will be some research to be done depending on your alternator manufacturer!

It is internally regulated alternators that have an external sense pin, if you do not know if your alternator has an external sense pin please call the manufacturer of your alternator and confirm.
