I started a new thread due to this no longer being an issue with the starter/solenoid on my 2155 that I originally posted in the Kohler engine sub.

I am intermittently (more often than not) losing voltage on the blue start wire on the solenoid when key is in the Start position. Sometimes it will read 7V and not start, and other times it will have the correct 12V and engage the starter to crank the engine.

If I disconnect the blue wire from the solenoid and check with a meter, it reads 12V every time I turn the key to Start. But once I plug it into the solenoid and check, that's where I'm seeing the voltage drop to 7V sometimes. I have already replaced the solenoid as well.

I tested the brake switch by releasing the brake and turning the key. I get nothing - no "click" signaling the starter Bendix engaging, no lights on dash. If I engage the PTO switch I get the same thing. So both safety switches seem to be working.

Where else could I check? What is causing a drop in voltage at the start pin of the solenoid? I know it has to be something on the ground plane of the start circuit, but I've looked over the wiring diagram and can't figure it out.

Also, if I jumper the hot wire from the battery post on the solenoid to the blue pin, it will start due it getting the 12V it needs. So I'm guessing the solenoid and starter are good...
