Have diodes checked in alternator.
One, if diodes are bad, it will allow 12v to bleed backwards out of battery to ground, hence dead batteries.
Two, diodes bad will put alternating not direct current into system, hence pulsing lights.
Put voltmeter on hot post(positive) of alternator. Measure AC voltage, not DC. If you have over about 0.5V AC you may have a diode problem.
