Still trying to rewire ignition switch on Craftsman ZTS Kohler 26hp twin. The S terminal on the ignition switch goes where on the solenoid? +terminal on battery goes to one side of solenoid with a wire from it going to top terminal of the relay. Other side of solenoid goes to starter, these are the two large terminals on the solenoid. There are two small connections on the bottom of the solenoid that I am not sure where they go. The connection on the bottom of the relay I'm not sure where it goes. I can read a schematic a little but the one I have is in black and white. I think it would help if wires were in color. My harness burnt and fused all the wires together. The schematic shows all the wires going into a bundle that's wrapped up and when they come out the other end I lose them, that's why I say color would help me. Thanks to everyone for the help so far. As you can tell wiring is not something I easily understand. I love to fix things. I always want to learn new things to. Thanks for any help.

Cambre, Look closely at the wiring of the schematic. Normally the wiring is coded for color with abbreviations like "b" black, "wo" white with orange stripe etc. Also it can get confusing when wiring goes into a connector one color and emerges another. Normally there is a key to abbreviations , sometimes on a lead- in page which can help. Also wiring can be very specific so that ideally your model is clearly spelled out on the schematic. I am sure there are diy aids on line which could also help in reading schematics. Hope this helps.:thumbsup:

Your first post you just wanted to bypass all switches and just get it running. Is that still what you want? If not You will need a wiring diagram for that year and model mower. You will just have to take your time and follow this diagram like a road map. You might even have to buy the right wiring diagram if you can't find one free. I find this can be very enjoyable work but just take one circuit at a time and think what power you are working with negative or positive and what you want to happen. You also need to understand electricity. Remember what all a relay or solenoid is a switch that turns on and off with electric.
Good info motoman: I sure will check the schematic I was trying to use. I did watch some ignition switch wiring on utube but not enough detail for me. Thanks, I am thick headed Cambre.
My first post is correct. I want to start it with the ignition switch. I have to jump the solenoid to start it. The ignition switch will kill it and has to be in on position to start but will not crank engine when key is turned to start position. One question I had was where does the wire go that comes off of the S terminal on the ignition switch? There are two small spade connections on the bottom of the solenoid. Where does each of these go? There are two connections on the solenoid relay. Where do they go. I do not want any safety switches. I use the mower mostly to tow a wagon to pick up rocks, limbs & haul fertilizer etc. I could put on a push button to start it but would probably have trouble wiring that. Thanks for the answer reynoldston
You have two big connectors and two small connectors on your solenoid correct. One large connector should have a large wire from the battery, and a small wire going ton the B terminal on the key switch. The other large terminal has a large wire going to the starter. There should be a small wire going from the S terminal on the key switch to one of the small terminals on the solenoid. the other small terminal can be wired directly to ground if you are not using any safety switches.
Thanks ILENGINE: Yes, two big connectors & two small connectors on the solenoid. That is what I needed to know. I knew where the large wires on the solenoid went to. Its the small wires that are giving me trouble. You have cleared up a lot. What about the relay, do I still need it? If so where does the connectors on it wire up to? Thanks ILENGINE
If you don't have a fuel solenoid on the carb. The only wires you need is the wire from the battery to the B terminal of the key switch. The wire from the S on the key switch to the small terminal on the solenoid, and a wire from the M terminal to the ignition module to kill the engine. Depending on the type of ignition on the engine. You may need a hot wire from the key switch to the ignition modules on the ASAM and DSAM type ignitions.

And an earth connection to the ignition switch so you can turn it off.
Most switches are marked on the back.
B= battery +12v feed
S= solenoid, 12 V to trip the starter solenoid
M =magneto, the small wire from the ignition coil
G= ground which connects to M when the ignition is off
The fuel solenoid needs a 12V feed from the A or L terminals on the ignition switch,
Most of the metal key switches are internal earth, plus G (ground) unless mounted in plastic or the switch is plastic. The solenoid would need to go to the L terminal because the A terminal wouldn't be hot in the start position. That was the reason I didn't discuss the ground side of the switch.
