Hmmmm, not sure that's correct Al.......  The voltage regulator will vary the
voltage to the battery based on the demand of the field wire.....  If the
voltage regulator is triggered to "charge" it will kick ~14.0 volts, in open
mode the thing will run from 12.0 to 14.O depending on load.....  The battery
is a capacitor by definition, and when relays are hooked to the battery (up
rf) you have less of a current fluctuation than if you put it at the voltage
regulator......   I'm sure there are more scientific electrical nerds that
can explain this bettrn me, have at it
