Toro Timecutter SS5000 - starter keeps running with key off

Hi, new to the forum.
My Toro is second-hand to me. The electronic brake controller failed along with the ignition solenoid, as it sat outside over the winter. (we moved recently, and shop was full)
I replaced the brake controller, solenoid, battery, and ignition switch. Now it will start and run, but starter still running after key switch is off. Fortunately I noticed this right away, as I was testing the new parts to make sure all was good.
I tried 2 other solenoids, so figure I ruled out a bad solenoid. (all were brand new)
I left small wires and battery wire on solenoid but removed wire to starter. Then connected starter wire to battery wire and motor started right away. When I disconnected starter wire from battery wire the starter stopped and motor kept running as it should. When I turned key off the motor shut off properly.
I'm considering simply installing a start button to make mower operable, but I'd sure like to find what the real problem is.
Anyone have an idea what's wrong?
Thank you!
 
I didn't think of that! But...when I unhook the ground wire from the solenoid the starter shuts off and disengages the flywheel. There's still power to the starter until I unhook that ground wire. I've looked for faulty ground wires, but haven't found anything wrong yet.
 
Like StarTech said, what starter switch did you use, they are not all the same internally. There is no such thing as universal fit.
 
I will check that out. Would make sense to be a grounding issue, when I have to unhook ground at solenoid to shut it off. I'll let y'all know what happens! Thanks!
