What are the three wires going to the starter?
Typically, a starter-mounted solenoid has three terminals with three connections: 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.
What wires go to the starter?
The negative (ground) cable connects the negative “-” battery terminal to the engine cylinder block, or transmission, close to the starter. The positive cable connects the positive “+” battery terminal to the starter solenoid.
Where does the starter cable connect to?
In that case, the starter cable connects from the starter to the solenoid, and the battery cable connects from the solenoid to the battery. The negative connectors in either case connect to the chassis as ground wires.
Can you reverse the polarity of a starter motor?
The current in a starter motor goes through both the armature and the field coils. Simply reversing the polarity outside the motor doesn’t change the relationship between the two.
Does it matter which way a solenoid is wired?
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.
What happens if starter wires are 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.
What does R mean on a starter solenoid?
R=relay provides voltage only when energized. See, when a starter engages it drops the battery voltage to approx. The Pull in is wired between the S and the big starter terminal. Current would flow until the solenoid engages.
What happens if you hook a starter solenoid up backwards?
Reversing them is likely to destroy the device and could cause a fire. Be very careful when working on the battery positive terminal.
