Re: (ET) crap - started mowing, and lost forward speeds

[David C Robie <mycroftxx1 juno com>]

Part numbers don't mean much on these they are so, so generic.  120Vac
10A contacts, 24VDC coil  DPDT.  The Radio shack had em but any hvac
supplier will have em also outfits that supply electricians.  As I
remember these were less than $10 each.  Try Digitron (mail order).  
They have the smaller (.187?)  male terminals rather than the big old
fashioned 1/4" ones  (like the fuse panel has)
