Thanks for all the responses, guys. Got a DVM this weekend, and checked continuity everywhere, and so far everything looks good. I searched the forum, and found some reports of unilite optical module failures - is it possible that this could be the problem? I'm somewhat doubtful, since I would guess that when the module goes bad, it's finished. Since my failure's intermittent, that wouldn't seem to be the issue. Didn't have the time to drive it until it failed, and go from there.

Thanks again,
