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.

What are the three wires on a starter solenoid?

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.

What are the 2 small wires on a starter solenoid?

The small terminal is for the starter control wire that connects to the ignition switch. One large terminal is for the battery cable from the battery’s positive terminal. And the other large terminal is for the wire that sends voltage to the starter motor itself.

Does it matter which wire goes on starter 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.

How many wires go into a starter?

To start and run a vintage car, you need only four wires—three for the starter and one for the coil. To recap: Thick, red wire from battery positive to threaded post on the starter motor. It can be a jumper cable, but if you need to move the car, a secured battery cable is much better.

Where do the 3 wires go on a 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.

What happens if you reverse the wires on the starter?

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 the I and S stand for on a starter solenoid?

S stands for “start”, not starter. I stands for “ignition”. As explained above when trying to start the car power is put to the s terminal and the solenoid is energized. The other end of the coil is connected thru the mounting bolts.
