fast88pu 3,313 #1 Posted March 17, 2019 I'm looking for a Toro or stens part # for a key switch. It has to be a 5 pole that fits the 5 pole plugs. It has to have power in all positions besides off and has to be grounded in the off position to kill the Engine. Thank you Share this post Link to post Share on other sites
pfrederi 17,147 #2 Posted March 17, 2019 That may be hard to find. That you want grounded in the off position would be a magnetp switch. But all the ones WH used in the starting position only B battery and S Stater terminals were connected. In run B A (accessory) and R regulator were connected. You do not want the S energized in run position or starter motor would never stop. You don't want acc or regulator while cranking. Share this post Link to post Share on other sites
953 nut 51,664 #3 Posted March 17, 2019 (edited) 103 991 should do the trick. In the "ON" position the "B","R" and "A" are all connected. In the off position the "M" is grounded and in Start the "B" and "S" are connected. Edited March 17, 2019 by 953 nut 1 Share this post Link to post Share on other sites
fast88pu 3,313 #4 Posted March 17, 2019 I need one for a tractor with an electric carb solonoid. That is hot in all spots but off. Off has to be grounded. So a ground kill. A battery terminal a start terminal and an accessory in the #2 position and also an accessory in the #2-3 position Share this post Link to post Share on other sites

fast88pu 3,313 #8 Posted March 17, 2019 430173 is a stens # for a newer vanguard. Wish I could find a wire diagram for it. Any ideas? Share this post Link to post Share on other sites
pfrederi 17,147 #9 Posted March 17, 2019 (edited) Worked on a neighbors troy bilt last summer had the carb cutoff Can't remember the model number and they are only summer folk so I can go lok at it sorry.. Look for an ad from loews home dept for a model number on something new then try to find a parts listing for it.... Edit ..wonder if any of the new Toro XI series use that technology??? 522xi has a fuel solenoid am guessing does the same thing Edited March 17, 2019 by pfrederi Share this post Link to post Share on other sites
gwest_ca-(File Mod) 10,496 #10 Posted March 18, 2019 In the drawing above they simply added diodes to the start wire and 12 volt supply with the key in the run position to power the carb solenoid. That prevents one circuit from back feeding the other. You will lose about .6 volt (1/2 volt) across the diode but should be plenty left to activate the solenoid.

formariz 11,849 #11 Posted March 20, 2019 @fast88pu I don't think this is what you are looking for but it is a different one. If it works I can direct you to it. In the run position L has power In start position only S has power Off position grounds M Share this post Link to post Share on other sites
