Ronald Hribar 84 Posted November 28, 2007 This summer two of my tractors developed the same problem. They would not shut off with the ignition switch. The tractors are 7116 with Briggs and 7117 with Kohler 20 hp magnum. Both systems require the switch to ground out the ignition when shut off. I finally got to working on them, fully expecting to see a broken wire at ignition switch. The wires are intact and test okay for continuity. My question is, the wire that comes from ignition switch and goes to terminal board along side switch, Is that how the switch goes to ground. Mine does not.

Chris727 1,844 Posted November 28, 2007 I thought the ignition switches grounded to the metal dash. Share this post Link to post Share on other sites
Jac 0 Posted November 28, 2007 Like Chris said, some ground through the switch. Check for continuity from the ground terminal to the body of the switch. Jack Share this post Link to post Share on other sites
wilm169 1 Posted November 28, 2007 The terminal board is where the lights and other ass. feed from. Share this post Link to post Share on other sites
BLT 715 Posted November 28, 2007 The Kohler has a 12V coil and needs a power source to run, switch contacts closed to run. The Briggs is just the opposite. It makes its own power and needs to be grounded out, so the contacts are closed to stop. Share this post Link to post Share on other sites
Ronald Hribar 84 Posted November 28, 2007 The orginal KT 17 needed a power sourceThe20 hp Magnum Kohler does not need a power source. If you send power to the ignition system you will burn up an expensive unit. The terminal board that the wire goes to the ignition switch . Only has that wire on it, so it can not be the lights. I'll check for continuity between dash, switch and ground. I find it strange that both machines developed same problem. Although the switch on the 7116 seems bad, at least the portion that the key fits in. Share this post Link to post Share on other sites

rsnik 1 Posted November 29, 2007 Every tractor I have got so far that runs won't shut off when you turn off the switch. I have been buried in home improvement projects and a navigation class I signed up for and have not done a hands turn of work on the 2010 Landlord I bought a month ago. The only thing I do know is that, as usual, the engine will not shut off when you turn the switch off. In this case it is clearly evident that the kill wire has dropped off or been accidentally pulled off the ignition switch. I have to prevent the bare end of the kill wire from touching anything to start the engine and just touch the wire to any ground to stop the engine. So far it has always been a hacked up harness or worn out/damaged harness to switch connector that is the culprit. Look down inside the harness to switch connector and check the female connectors. In my case they were hopelessly corroded, missing or just wore out. As I mentioned to Keith a short while ago a new harness and harness to switch connector can be bought here: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&rd=1&item=180152041187&ssPageName=STRK:MEWA:IT&ih=008 I bought new switches and still no joy; it was the harness and the connector. The harness itself where it connects to the connector gets basically rotten; the wire turns green about a half inch down into the insulation and resistance soars. Dunno 'nuttin about your Kohler Magnum. I have only owned Briggs. Share this post Link to post Share on other sites
