I have a red flashing light on my spark module. I don't know what that is telling me. There are no arrow codes that i can find on the unit. I have 24 volts coming to the board but not sparking my ignitors. I need to know what i can jump out on the board to see if i have a bad ignition board, or do i have a bad electronic board. The 24 volts does not leave the top post on the board. The red light just blinks without stopping.
