Get the battery checked ... and also alternator charge rate as well ... may be an alternator on the way out. Do you have any power steering fluid leaking onto the alternator???

Regulator on its way out or the main (thickest) wire from the alternator to the battery has become brittle from heat being close to the engine and has frayed inside the insulation close to the alternator. Get someone to gently shake the wire while it's idling (watch the fingers) and see if the light blinks. Also check the related fusible link at the battery (try the wiggle test with that too).
