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...

This the before photo of the red wire going on its sparker thing via a spade terminal on the end. At some point today that broke off so there was no place to slide on the wire terminal for it.
I widened the wire terminal so it would wrap around the end of the probe end and squeezed it on tight.
If that didn't work that might be why there is a click but no spark down at the sparker end above the screen? Thinking of MT BOB's idea there.
That spade that broke off was like it had been bent back and forth too many times and I bent it one too many times. If it has been sort of just hanging there since who knows when (years?) perhaps that would explain some of this?
OTOH, once it sparks and it fires the gas, does it ever spark again until the next cycle? I was having the burner cut out and then spark re-light several times during a cycle until the last one that got the Tstat to shut it off. After the RV cooled down, it would start again by Tstat and same story on and off till the RV got back to Tstat shut off.
My new three prong part should take care of that red wire connection if that is now too bad to work right, but that leaves maybe a ground issue or any of those other things on the list it might be.
I could try to solder that on where it is squeezed on, but not sure it would "take" or just be a cold solder with that metal.
