tallen4392 67 #1 Posted December 23, 2017 Was using my c-81 today started right up after 4or 5 min just quit no will not turn over but will start with power put to the starter I checked all the wires and connections look good when I turn the key only the battery side of the selonide is hot should I have power to the small wire when I turn the key the thing always started right up like today but today it just died hard to figure out any ideas ???? Thanks Share this post Link to post Share on other sites
tallen4392 67 #2 Posted December 23, 2017 Is there a fuse somewhere that could cause this that is what it felt like I could not find one Share this post Link to post Share on other sites
Ed Kennell 35,798 #3 Posted December 24, 2017 Yes, you must have 12VDC at the small terminal on the solenoid when the switch is in the start position. Connect a jumper wire from the + battery terminal to the small lug on the solenoid. The solenoid should click in and the starter should turn. If it doesn't, the solenoid is bad. If it does crank, then the solenoid is OK and it is not getting power from the switch. If you have a good wire from the solenoid to the switch with good clean connections, then the switch must be bad. If the tractor runs OK then you have power to the switch, but the switch is not connecting power to the start terminal. 2 1 Share this post Link to post Share on other sites
953 nut 51,721 #4 Posted December 24, 2017 With any electrical problem the first step is to clean and tighten ALL electrical connections including grounds. A bad ground connection is often overlooked and is as important as any other wire. Not sure if your engine is on a "shaker Plate" but lots of '79 to mid '80s had the isolation mounts and the ground wire from the frame to the engine could give these symptoms. 1 Share this post Link to post Share on other sites
tallen4392 67 #5 Posted December 24, 2017 I spent hours checking tightening all I could did not see anything from engine to frame will check tommorow was wondering if the small wire on the selonide should get hot when you turn the key only the battery side is hot when u turn key Share this post Link to post Share on other sites

tallen4392 67 #7 Posted December 24, 2017 Yea that’s what I thought that wire is dead when you turn the key just weird because it started right up like always then died after a few now no power to that lug but if it lost power to that wire it should of stayed running correct I saw your post after thanks Share this post Link to post Share on other sites
tallen4392 67 #8 Posted December 24, 2017 Is there. A switch on the brake or clutch pedal that would give me that problem Share this post Link to post Share on other sites
953 nut 51,721 #9 Posted December 24, 2017 The brake switch prevents cranking but has nothing to do with ignition. Is the PTO off? Are you sure the 25 amp fuse between the battery and amp meter is good and the fuse holder is clean? Withe the key on dose the amp meter show discharge when the lights are turned on? The amp meter could also be the problem. The start/ignition switches on garden tractors has a brass disk with little humps pressed into it which is under spring tension and is moved with the key. Could be the key switch. 2 Share this post Link to post Share on other sites

tallen4392 67 #16 Posted December 25, 2017 Thanks the red wire on the switch is hot at the back of the switch when key is in start position Share this post Link to post Share on other sites
tallen4392 67 #17 Posted December 30, 2017 Anyone know where the clutch interlock switch is near the pedal or at the back of the tractor Share this post Link to post Share on other sites
Ed Kennell 35,798 #18 Posted December 30, 2017 It should be just inside the pedal. The ear the rod is connected to slides across a ball that makes the switch. Share this post Link to post Share on other sites
