ignition controls
(OP)
I have looked in a few text books but can not find out how flame rectification works internally of the ignition control, how it works with a single igniter/sensor, how to check flame signal on HSI or single igniter/sensor system.
Can anyone point me to a good textbook for these answers or give me an answer?

RE: ignition controls
You could also search the control sites such as "Fireye" for example.
You will see how it works like a 1/2 wave rectifier based on the relative size of the small flame rod/HSI with respect to the larger grounding area of a burner.
An AC current is applied by the ignition control, the flame signal will approximate pulsating DC.
