My gas fireplace has an electric spark ignition that isn't sparking. I'd like to 'test' it, but I'm not sure what a working one would be doing.
The spark contact has 120VAC with 4A current when I hook up my multimeter from the 'high voltage' to the 'burner return'. I would have thought it'd be enough to cause an arc of sorts, but even when I use probes that are very close together and attached to the terminals, no sparks.
How, generally, do these things work and where might I start in debugging it? Should I expect sparking with that kind of current?
I'm especially curious if the black circular part in the bottom left can be identified (there are no markings on it and I don't even know what kind of thing it might be).
This control module is RAM-1MC1-06, if that makes a difference.
