What activates the starter relay?
The Starter Relay is a device that utilizes a small amount of electrical current from the ignition switch to energize an electromagnet that operates a larger current carrying switch, which in turn triggers the operation of the Starter Motor or Starter Solenoid.
Is the starter relay and ignition relay the same?
In some automotive applications, the starter relay works together with the starter solenoid to operate the starting system. In others, the ignition switch operates the starter solenoid circuit directly. These are usually the small vehicles whose starter motors do not require large amounts of current to work.
What wire goes from ignition to 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 ignition switch wire go to?
Connect the ignition wire to the “IGN” terminal of the ignition switch. This is the main terminal that is used for vehicle ignition, wipers, accessories and other operating features. This is the normal “run” position of the switch.
What FUSE will keep a car from starting?
A blown fuse in the starter circuit could be the cause of a no-start problem. Often there is a fuse and relay for the car starter in the fuse box but sometimes they will have external fuse on the fuse line or close to the car battery. The starter motor fuse is usually big and it will not be in the fuse box.
What is the purpose of a starter relay?
A relay’s purpose is to interpose between the ignition switch and the powerful, current-hungry starting motor. This allows a minimal 12-volt signal from the ignition switch to activate a magnetic coil in the relay that pulls in a very sturdy contactor switch that is capable of supplying the full battery current to the motor.
Where is the ignition switch on a starter?
They might be 10 gauge or larger wires depending on the vehicle and starter size. Connect the smaller terminal or terminal post marked SIGNAL, SWITCH or IGN to the ignition switch. This terminal goes to one side of the magnetic coil inside the relay.

What are the signs of a bad starter relay?
Broken or corroded wiring – Damaged or dirty wires to the battery or to the starter solenoid (or wires that are loose) can prevent sufficient power from reaching the starter. Alternator – The alternator is designed to power all of your car’s electrical systems when the vehicle is running. It also recharges the battery.
