Quote: If you talk to the guy it wont seem overpriced. The voltage regulator is of higher quality than the off the shelf units, so that right there is enough of a justification.
This is pretty handy>> "If you want to adjust the voltage regulator you use the screw on the back"
I'm pretty sure AGM batteries don't appreciate a constant 14.5V. A Chrysler computer typically wants to command something like ~13.6V but still needs to know what the voltage is to skew sensor's reference voltage appropriately. MS3 may not care so much, but at least this regulator allows adjustment and a AGM battery will last longer.
