rick 233 #1 Posted September 30, 2022 I need ignition switches for my 73402 314-8 and my 41-16OE01 416H. I have searched and found the following numbers, # 111216 or # 103990 for the 416H #116338 for the 314-8. I would appreciate a second opinion since neither of the parts are cheap! Thanks, Rick 1 Share this post Link to post Share on other sites

It could be that other problems are causing problems and we would be willing to help trace the problem down. 2 Share this post Link to post Share on other sites
peter lena 8,625 #4 Posted October 1, 2022 @rick agree with others above on possible switch selection, also a good opportunity to go over every connection aspect of your lay out . stressed cracked wires and their connections are often guilty of causes , as are lack of grounding to chassis . DO NOT COUNT ON ORIGINAL GROUNDING POINTS , often corrosion , paint , rust . is in the way . bolt on an electrical lug , to your battery ground cable bolt down point , for a feed to enhance your grounds . verify your grounds , don't just think they are there. verify as you go , as to function, stop and change whatever is causing issue . those safety switches , are often cracked / corroded . good luck with it , pete 1 Share this post Link to post Share on other sites
rick 233 #5 Posted October 1, 2022 (edited) The switches are worn out. There was a little confusion in the IPLs from different sources, I just needed some confirmation. Edited October 1, 2022 by rick addition 1 Share this post Link to post Share on other sites
gwest_ca-(File Mod) 11,041 #6 Posted October 1, 2022 103990 can be easily found saving some $'s but the 116338 appears to have to come from Toro. 1 Share this post Link to post Share on other sites

Does the 116338 cross to 103991? I thought that was the P/N for any tractors equipped with Magnum engines? I may be wrong, but I think 103991 covers most magneto equipped tractors, and 103990 covers most tractors with powered ignition systems.

If you were to move a few wires around on the plug that connects to the ignition switch you could get by with it. You can get an aftermarket 116338 on the internet auction site for $ 46.00 https://www.ebay.com/itm/113152370753?hash=item1a58682841:g:uD4AAOSwaLxeb2Em&amdata=enc%3AAQAHAAAAoM3CFHaQdAkf3yFbZr2MZhq%2FIN4NAdK 103991 1 Share this post Link to post Share on other sites
rick 233 #9 Posted October 3, 2022 I want to thank everyone for their help and suggestions. Now I need to spend some money! 2 Share this post Link to post Share on other sites
rick 233 #10 Posted October 4, 2022 (edited) Switches ordered from Jack's yesterday. Parts order from OPEengines.com arrived today, now I get to remove the starter from the M14 to service the starter drive. Needed a gasket for the oil dipstick tube which is in the way. Always something to do!! Edited October 4, 2022 by rick added content 1 Share this post Link to post Share on other sites
rick 233 #11 Posted October 4, 2022 I fixed the starter on the 314-8 while Eli (grandson, almost 3) was napping after lunch. We keep him 4 days a week while his parents work. A 3 year old will keep you busy! 1 1 Share this post Link to post Share on other sites
