Farmall 504, Diesel, Solenoid Wiring

Green horn here with a wiring question regarding proper solenoid wiring on a diesel Farmall 504.

It is important to relate the following: The engine is frozen. I've disconnected all harness leads in an attempt to simplify an attempted restoration. The only elements currently wired are a new starter switch, a new glow plug button, new battery and the original solenoid.

Briefly, the solenoid hosts three terminals. (1) The "S" terminal on the top of the solenoid is connected to the "ignition" terminal of the starter switch.

(2)The positive battery cable is connected to the battery terminal on the solenoid. Also connected to the battery terminal on the solenoid is a lead to the "battery" terminal located on the switch. Lastly, a third wire is connected to the battery terminal on the solenoid and this wire is connected to the glow plug button.

(3) The third terminal located on the bottom of the solenoid is not connected. (Before disconnecting the wiring harness there was no attachment here).

Grounds: The switch is grounded properly. The battery negative harness is grounded properly.

Issue: When activating the ignition on the key switch the solenoid clicks without more. Also, there is a small amount of smoke that appears at the battery terminal lead on the solenoid. Granted, the engine is frozen, however I do not hear the starter engaging.

Question: Is this an acceptable method of wiring this tractor so as to test the starter or turn the engine once I have freed the pistons?

Note: I have looked at the wiring schematic for hours without resolution. Please see the same attached. If it is not attached it is because this site will not let allow it and I will continue to try.

Thank you for any advice you may have

Take it one step farther. Remove the starter, leave wires hooked up, ground the starter to frame with a jumper cable and then try it to see if starter engages and runs. From your description of your wiring, you have not included the push button starter switch. Hot wire from solenoid should go to key switch, through key switch when turned on to push button, from push button (when pushed) to the s terminal on solenoid. The other small terminal on the solenoid is a ign bypass terminal used only on spark ignition tractor. If engine is stuck like you indicate, activating the starter will only damage starter and ring gear etc if repeatedly done. When you have starter off you will also have the best possible place to try turning the engine over by using a bar on ring gear.
