Fireplace main burner not lighting . .. .pilot is fine
I ordered a new ICM and that fixed the problem.  In checking the voltages at the valve TH to ground is now 1.92v.  Also, the red and green LEDs on the battery relay are now brightly illuminated.  With the defective ICM they were very dim.  Thanks for all your input.  Hopefully this will help others in the future.﻿
