Martin G 0 #1 Posted July 16, 2021 Hello everyone! I'm working on my friend's B-100 Wheel Horse. He can start it with the key sometimes... This leads me to believe that one or both of the interlock switches have gone intermittent. Finding the one on the clutch pedal is easy, but where is the one for the PTO? Also, anyone have a part #'s, or aftermarket part replacements? Thanks! Share this post Link to post Share on other sites
gwest_ca-(File Mod) 11,046 #2 Posted July 16, 2021 Sorry we do not have a wiring diagram for the B-100 8-speed. This may be the pto switch and should be just inside where the pto lever goes into the hoodstand. If not correct let us know. The 1975 model wiring 1 Share this post Link to post Share on other sites
