Dan,

Thanks so much for your response. I'll be able to tear down and test
this weekend and will hopefully be back up and running.

Another question has been bugging me for a few days. How much effect
does ripple voltage have on the Geckos and will too much ripple cause
damage.

Thanks again,

Chris
