I bought a used spreader unit. I got the motor running on it's own. Now I want to wire it up so I can use the electric start. It's currently wired according to the picture attached. No dice. The switch, solenoid, are both brand new. The acronyms on the switch are accurate. I assumed "ST" meant "starter"? *shrug* Any experts please lend your expertise. Oh.. yes i know..the artistry is astounding. No autographs please. Shoot.. I actually have the "ST" terminal grounded with along with the NEG battery. Darn it.
