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...

Different places.
Easiest from your photo, is from either side of the circuit breaker to ground. Metal housing should work.
Better place is on left side not shown in photo, is incoming power. Not the blue wires as they are thermostat leads. Should be red and yellow leads.
