Are the battery terminals clean and tight? Also, did you check the ground wire to the engine block to make sure it is in good condition?
Let me know. Also, I attached the wiring schematic below for the circuit. If all wiring is tight and clean, have a helper turn the key to the start position while you check for power to the black wire at the starter motor. If you have power, chances are the starter is faulty. Note that the black wire (trigger wire) only should have power when the key is in the start position.
Let me know what you find or if you have questions.
