Mopar P-3690732 Constant Voltage Regulator

Personally I think all the hype about these is over-blown. WHAT IS THE JOB of a "voltage regulator?"

Why, it's to REGULATE VOLTAGE. In other words, to KEEP VOLTAGE CONSTANT

One of the infamous on this site went into a big lecture on how "they don't" because they are epoxy coated and you have to grind it off the mounting to GROUND the thing. Well GEEZUS!!! That is true of ANY voltage regulator!!!!

Most overcharge (over-voltage) problems are caused by VOLTAGE DROP in the harness. How does this work? The harness carries power from battery through the bulkhead, through the ignition switch, back out the bulkhead, to the ignition system, the VR, the alternator field, electric choke, if used, and smog doo dads on some cars

By the time "it gets there" there is voltage drop. So the VR says, HEY!!!! We are getting LOW VOLTAGE to "us." SO LET'S RAMP UP the alternator. So what happens is, the VR ramps up the alternator until the VR IGN/ sense terminal is 14X whatever. But because this point is at the low end of the harness, THE BATTERY is above that by whatever the drop is. On my 67 when I bought it, the drop was over 1.5V!!! The battery was seeing 15.5 volts or more
