Tally so far:
358: LEDs flash during learning. After, either error light or nothing. Replacement board works fine.
456: Totally dead, 78L05 has no output
1357: Worked, then 78L05 fried. Maybe anti-static bag?
1625: Fried regulator??
2144: Board works, LEDs do not light. Reversed LEDS (with FIRST's blessing) and all is well.
2199: Error LED lights sometimes, not "0" (learn loop) LED

Aren_Hill: So far the advice has been to inform FIRST and NOT to replace it yourself.
Please elaborate: What makes you think the regulator is fried??
