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 does the 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 color wires go to the starter solenoid?

The solenoid is basically an electrically controlled switch. The battery power is on one side and the starter load is on the other side, the blue wire from the ignition switch energizes the coil of the solenoid to close the switch connecting the battery to the starter.

Which terminal on a starter is positive?

Connect the voltmeter across the solenoid terminals, the negative lead on the feed (battery) side, the positive on the starter side. Switch on the ignition switch - if the voltage still does not drop below 0.5 volts, the solenoid or the ignition switch or its connections are faulty.

What happens if starter is wired 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.

Can you hook up a starter backwards?

Additionally, what happens if you hook up a starter backwards? Most starters change both fields when reversing the wires causing the motor to spin ALWAYS in the same direction. The positive cable connects the positive + battery terminal to the starter solenoid.

Can a starter turn the wrong way?

Yes, it is possible to assemble the starter motor wrong and have it run backwards. Usually, the yoke has been flipped 180 degrees and simply has to be flipped back. If it is backwards, when operated, the one way clutch would just spin and never engage the engine.
