1810 no spark looking for help
 

Hello
My camp mower 1811 does not have spark and I am looking for some advice. I have the electrical diagram which has been pretty good, but the wire colors are shuffled and I am not good enough with that to tell what the cub wants out of a given switch. I have only owned this cub for a year and of course stuff has been bypassed. The seat switch has the connections pulled out and taped together, the reverse switch (its up under the dash so the lever hits it) is broken, the lever is gone so it never gets actuated (its open). I am not getting 12 volts on the yellow wire coming off the ignition switch, going towards the engine/magneto. I am usually pretty good with the schematics but with the stuff bypassed or broken I am not sure where to look
Thanks

The 1811 has the Magnum 18 (M-18) Kohler engine in it. It has "Magneto" ignition. You do NOT need 12V to start or run the engine.

AS A TEST... Pull the Yellow off the Ignition Switch and see if the engine starts and runs.

PS I said it was an 1811, this is the 1810

I will try pulling that connection
thanks

Makes no difference. They both had M-18's.

Did this no start happen after you bought it or is it more recent?

Thanks, I didn't want to assume they were the same wiring. I have a better schematic now, looks like more of the wires are the correct color anyway. This mower has the 3 way PTO switch, if I read the old posts right that means it is a 5 connection switch right? I did notice when I was ringing things out last night that the yellow wire (going to the engine) had continuity to ground. So guessing that is the problem and disconnecting that, as you suggested, will enable the spark.
Next mess is the front seal, its leaking badly and has made quite a mess out of the entire engine area, but I am more familiar with that
I appreciate the help

The Yellow Wire is the KILL CIRCUIT. Grounded it will stop the engine. NOT grounded will allow the engine to run.

unplug the connector at the engine to see if you get spark, if not then it's in the engine, if it gets spark then it's outside the engine

From post 7 I am assuming that disconnecting kill wire did get it running for him.
