Ordered already, good mailing price to Canada BTW, less than inside Canada!! 

Thanks Kevin and Chuck --I am sure that is correct, will order that piece and proceed.  John D

Had this one some years, has been stored for two and on getting back on track, smoke/steam comes out like crazy especially as I get to 10-12 volts (yes i remember don't go too high here) but apart from a little movement at about 4v DC I get no further movement just noise from motors??? Any suggestions.
