C105 with K241AS 10 hp - intermittent ignition failure

Recommended Posts

New to WH world and this forum. Got a 1980-83? C105 with K241AS 10 hp with intermittent ignition failure. Sometimes the key simply won't get anything. No click or burp. This happens with no consistency. Hot, cold, warm... Usually, I jiggle key or wires and it's enough to get it going but I am concerned it will just get worse.  

Thoughts or or suggestions welcome!!!

Sounds like you found the problem. The connector at the ignition switch needs to be cleaned as do the prongs on the switch. Shiny clean. A dab of dialectic grease applied after cleaning will help keep moisture out and the oxidation/rust from moving in.

      12.6 volts in the battery and at the starter connection.
      10 volts on the gauge.
      Nothing when key is turned on.

      I'm having some trouble with my 418-A. I think it is ignition related, but I'm not completely sure. It starts and runs perfectly fine, but when I go to turn it off, it doesn't work. I can just turn the key into the 'off' position and take the key out while the tractor is still running and it will continue to run as if I hadn't turned the key off.
       
      I'm trying to keep this tractor as original as possible, so I don't really want to buy a new ignition. Any help is appreciated. Thanks!

      I have a few basic electrical system diagrams that are helpful in understanding how the wiring system works. They are not specific to any particular tractor and do not include safety switches. All use the 5 post ignition switches 103-991 for Magneto and 103-990 for Battery Ignition. I failed to include fuses in the Starter Generator drawing, this is an over-site and I would encourage fuses be used as shown in the other two drawings. 
      Hope this is helpful.

      I have I believe is a 73 commando 800 8hp kohler k181s put a new switch on it due to starter sticking on and got a new starter and completely charged the battery and new solenoid has power to the battery side of solenoid but not starter side but will turn over if jumped has no power going to the switch. Wondering if anyone had this problem before

      Let me first say that it ran when I brought it home.  Drove it around the guys yard, tried out the mower, drove it onto the trailer and drove it off the trailer and into the garage.
      I've done a "ground up" restore on the tractor (70 Charger 12).  Swapped out the breakerless for a battery ignition and swapped out the 10 amp for a 15 amp stator, flywheel and regulator.
      Pulled the head, looked pretty good, new head gasket and head bolts.new fuel pump, fuel lines,new switches and wiring, new aftermarket carb, new coil, coil wire, new points, new throttle and choke cables.
      Static timed (twice just to make sure) Have tried Autolite 216's and the hotter 437's. changed the condenser to the high dollar Kohler one.
      It will idle but when I give it some throttle it stumbles or will rev up a little then quits.
      I've gone thru the "trouble shooting " steps multiple time and to no avail
      Anyone got any ideas??  I am willing to try most anything at this point
