I tried firing up the BS tonight for a test light.
My ignitor seemed to be faulty because no matter which way I put in a number of AA batteries, nothing happened.
I consulted this board and a user confirmed positive side out / towards front of unit.
Then I noticed that the battery only made good contact and resulted in clicking if the knob seemed a bit "springy" when tried to screw it in. I assume that means the spring wasn't making contact in the other instances.
So now finally have a clicking sound. However, even in the dark this evening, I didn't see a spark.
I know I have gas flow because I lit up the BS manually.
