Main flame generates a milivot signal (flame ionization) that 'proves' main flame.
Signal goes back to circuit board via spark electrode/high tension wire.
I would be checking for 'trace'....cracks in ceramic allowing signal to go to ground.
Also check the resistance on solenoids.......roughly 40 ohms
