gwest_ca-(File Mod) 11,701 #2 Posted Thursday at 03:15 AM Have a tractor model and serial number? Some used 3-terminal switches some 9-terminal and some are toggle and some are push button. Have a test switch part number? 1 Share this post Link to post Share on other sites

gwest_ca-(File Mod) 11,701 #5 Posted Thursday at 04:25 AM Uses just 2 of the wires. 1 Share this post Link to post Share on other sites
gwest_ca-(File Mod) 11,701 #6 Posted Thursday at 09:34 AM Just a guess but I would put red to the C or common wire and the grey to the NO wire. NO is normally open which is when the switch is at rest. If it does not work you would need to change the grey to the NC terminal. Normally closed is when activated. They are using just 1/2 of the switch. The switch in this diagram is shown NO, 1 Share this post Link to post Share on other sites
