Chances are, the green wire connects to the SMALL GROUND terminal of the solenoid and goes to a safety switch that has to be “activated/closed” to complete the ground circuit to the solenoid “trigger” side. This closes the “switch” to the LARGE studs and allows current to flow from the battery to starter motor..

What happens if you wire a starter solenoid backwards?
When reversing the wires, most starters change the fields to cause the motor to spin in the same direction. It is difficult to connect the positive wire from the battery to the negative of the starter, so you have to make a short circuit.
How do you wire an ignition switch to a starter?
Does it matter which wire on a solenoid?
If they are connected to a terminal, you are good to go. The small gage wires on the small terminal are the same as the small gage wires on the larger terminal. It does not matter because it isn’t specified in the instruction manual.
Can solenoid be hooked up backwards?
What Happens If Solenoid Is Backwards? A reversed direction of current would cause the magnetic polarity of the solenoid to change as well.
How do the wires go on a solenoid?
How do you determine the polarity of a solenoid?
English: Right hand rule for polarity of a solenoid: If the solenoid be grasped in the right hand, so that the fingers point in the direction in which the current is flowing in the wires, the thumb extended will point in the direction of the north pole [of the solenoid].
How do you wire a solenoid?
What is polarity of solenoid? To find the polarity of a solenoid, you can use the right-hand rule for current (or left-hand rule for electrons since they go in the opposite direction to the current). To do this, point your right thumb in the direction that the current travels in the coiled wire in the solenoid and curl your fingers.
Where does the ground wire go on a starter?
A typical starter ground path goes from the starter housing to the engine block. Or, it runs from the starter housing to the transmission case and then to the engine block. The negative battery cable completes the ground circuit from the block to the negative battery post.
How do you cross a starter motor?
Which wire is positive on a starter?
The “B” or “battery” terminal: The terminal that connects the solenoid directly to the positive battery cable. The “S” or “start” terminal: The terminal that receives power from the ignition switch. The “M” or “motor” terminal: The terminal that attaches to the cable that connects to the starter motor.
Which side of the starter is positive?
To check the solenoid and ignition switch, connect the voltmeter across the solenoid. Connect the voltmeter across the solenoid terminals, the negative lead on the feed (battery) side, the positive on the starter side.
How do you test a solenoid wire?
How do you bridge a starter solenoid? 
Why does tapping on a starter make it work? This works because the brushes wear out which results in an inadequate electrical contact. By gently tapping on the back of the starter with the hammer, the brushes are knocked back into place so they can make contact one more time.
How do you bridge a starter relay? 
How do you wire a solenoid valve?
What happens if ground wire is not connected?
The appliance will operate normally without the ground wire because it is not a part of the conducting path which supplies electricity to the appliance. In fact, if the ground wire is broken or removed, you will normally not be able to tell the difference.
Does it matter which wire goes where on a solenoid?
It doesn’t matter which terminal you place the battery power cable on. If they are connected to a terminal, you are good to go.
How does a two wire solenoid work?
How many wires are connected to a solenoid?
A solenoid consists of a single electrical component, namely its coil. The coil requires only the connection of two wires running to the live and neutral points of the power supply in the case of an alternating current (AC) solenoid or the positive and negative points of a direct current (DC) example.
What color wires go to ignition switch?
Ascertain the positive power lead from the battery to the vehicle’s ignition switch. It is often a thick red wire that is always energized. Once you have identified it, fit the right terminal end on the power lead wire and secure it with a terminal multi-tool.
What do letters on ignition switch mean?
“R” is typically to indicate “red wire” out to components that need 12V power in the RUN position of switch (Cub to name one). “S” indicates starter control out. “L” can indicate lights if lights function is part of the key switch duties (may have other functions on different machines.
What does the small wire on a starter do? the small wire is the solenoid wire. when you turn the key thats what sends the power to enguage the starter gear. take that wire off and have a friend turn the key forward while you use a test light to see if you are getting power to it. there should only be power to it when the key is all the way forward.
