OK, fellow Samurai-ista's, here was my problem(s)...
First, an intermittent continuity problem in one of the leads going to the flue gas sensor. The wire connector under the shrink wrap was broken, but occasionally it would make contact and work for awhile. Hence, when I jumpered it out, that didn't work cause the break was in the wire connector. I should have noticed it being a bit too flexible, but hey, they looked skookum and I didn't even suspect that would have been it. I was all set to blame it on a failed electromagnet, but not so!
I also seem to have a bad flue gas sensor which if wiggled, or even breathed on, will break continuity, so it needs to be replaced too.
I've got it working now, but will still go ahead and replace the thermocouple as well as the flue gas sensor so all the components and connections will be new, just to get it back up to snuff.
A thorny problem that I eventually figured out...Thanks for the replies, one and all.
PS: My favorite beer... dang, who can say, there are some really excellent ones out there now. Lately I've been swilling my fair share of Ninkasi "Total Domination" or Re-New Ale (out of Eugene, OR) and the Pyramid Outburst is a whopping 8.6% with darn good flavor. Try em!
