I think I should probably clarify that the last time it got wet was about a month ago, and it was running fine up until a week or so ago. I'm skeptical moisture is causing my problem, since it hasn't seen a drop in weeks. Additionally, I sprayed out every connector with WD40 for good measure.

The only reason I mentioned the power washing from a month ago, was that maybe whatever was getting wet finally took a dump, even though it was dry when it did take a dump.

Perhaps the PO left the key on, and the transistor in the ignitor was damaged and worked intermittently?

Thanks man! That's super cool of you. I ordered one from evilBay that should be here in two days, so I'll just sit tight. Fingers crossed! Or else there will be a RYCA S40 for sale  

Superb news.  Congrats.

Can you do us all a BIG favor?  I just did a post on igniter box checkout.  Could you check out your old igniter box following the guidance in that post?  Maybe let us all know how it goes.  It would be very beneficial to all of us if we had some idea if a bad igniter box has resistance/continuity values that vary significantly from the values I got on my wringout.  Might make it a lot easier for others to troubleshoot in the future.

Good job.
