8531 /Burner Issue UPDATE--Photos ( Fixed!)
With the furnace running, where do you put the pos and neg leads of the meter? Or can you do it at the Tstat inside with the furnace on? I want the 12v to the board, not the voltages the board puts...

I had this problem before (two years ago) and got some help on here with it all, and swapped some parts from a 111 I got off a guy. Eventually I got a 111's board from a 98 MH being parted out and that got it working right. New burner head (old one had screen rusted out) Now it is starting to act up again.
ISTR I swapped the squirrel cage fan-- found out how to get it off here--that was to try a new limit switch you have to get the fan off first to get at.
The one in there now is metal and heavier than the plastic one I have in the spares box. Can't remember which is the 11 vs the 111's. Anyway it spins ok, and the delay for burner on at the start after fan runs and then at the end for fan to stay on after burner off is working right.
It is just the burner cutting in and out when it should just stay on.
I can haul the burner end out again and check the wiring for the flame sensor and however it is grounded. Is there a way to check the voltage with it out? Maybe turn the Tstat to on? Is there any voltage when there is no gas?
