while idleing my dash lights pulsate (repeatedly dim then brighten to normal)

What is your question?

while idleing my gauge cluster lights pulsate (dim then brighten to normal (this process repeats itself)). It's a distributorless ignition system. The components are as follows- PCM, CKP, CKP trigger wheel, and coil pack. I'm unsure can we narrow it down it's probably the alternator regulator but maybe just the coil pack
