TSU warning light

Thanks to all who replied...so much to know/learn.  I did pull the servo apart and all appeared to be fine, put it back together tested it before hooking it up and it cycled as it should, still not sure why it wasn't working before, but now it is.  Hopefully won't have any more problems with it, but if i do i'll know where to look!

Best,

jonathan

If only all repairs turned out to be that simple...
