need Armstrong igniter advice
Looking at an Armstrong 80 GUJ100D12-2B furnace that's not igniting but I am unfamiliar with the hot surface ignition system. Just trying to determine if it's the gas valve or igniter, What kind of voltage should I be seeing on the igniter leads? I'm getting 6 volts.

Is there a smart valve on that furnace?

Hey rundawg, do you have any sort of file on ohm reading for different ignitors? I just would like something to save or else I forget.

The resistance of a Norton silicon igniter used in the Q3450 or Q 3480 pilot assemblies, when new and
cold, will be between 3 and 4 Ohms (average 3.7 Ohms) as the igniter ages the resistance will increase. When
its resistance reaches 10 Ohms the igniter should be replaced
anyone have a better cut & paste about the ignitorsIt`s better to be silent and thought the fool; than speak and remove all doubt.
