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 got it working.
First I found the spare three-prong thing I couldn't find yesterday, which took care of that connector I broke on the other one. (I cancelled my Amazon order for a new one)
I swapped out the relay with the spare and doing that found the short red wire to the top of it (the one that was there before) from the bottom of the circuit breaker was loose on its top connection at the relay. So now the voltage at the top of the relay connection is the same as at the circuit breaker.
That voltage seems low to me compared with battery voltage and the video guys seem to get closer to the battery voltage on theirs. Whatever, the furnace fires right up at the start and keeps running. I won't know till another time if it keeps running all the way, but at least we can go camping now.
EDIT: It ran the RV temp up from 9C to 15C Tstat setting and stopped without cutting in and out. Looking good!
Thanks everyone for all the excellent advice and info working with this. :)
