OK
my alternator is charging and within spec
but with the car running and alt putting out 14 volts
my warning lights for door ajar , parking brake ,low fuel and the little red light behind the volt meter stay on
just like if alt belt has broken. but I know that alt is good and putting out 14. volts
situation does not change with engine rpm or anything else
does anyone know if there is a relay in this system that can cause such problem?
please respond
btw just in case I pulled alternator and tested, cleaned, and installed a new voltage regulator so I know that the alternator is good
thanks much

Load down the electrical system with all the load you have and see if it still pushes 14vdc. Turn on everything and check it out.

with headlights, blower motor, wipers, interior lights on
still 14volts at 900 rpm
still warning lights on
