How do you wire a starter relay to a starter switch?

Find the thin pair of wires from the ignition switch circuit. Connect one of them to the smaller metal stud terminals on the starter relay. This is the wire that will be carrying low current from the ignition circuit to the coil winding of the starter relay.

What does a starter relay do on a car?

The starter relay enables the flow of current to the starter solenoid and motor. If it fails completely, it means the starter solenoid not working the plunger, and the motor not coming to life.

What should I do if my starter relay is not working?

Check the starter relay wiring one more time and then test by attempting to start the vehicle. If the vehicle won’t start, check for a strong click from the relay when it is initiated. Check for 12 volts at the relay input to the coil with the meter’s negative on the frame of the vehicle.

Why do starter relays get so hot?

There are wires from the external starter relay to the starter motor, which can create additional heat if the wire size is incorrect. In addition, external starter relays tend to have easy access for someone to tap in a fuseable link to a stereo amplifier.

How do you wire a starter relay to a coil?

Find the thin pair of wires from the ignition switch circuit. Connect one of them to the smaller metal stud terminals on the starter relay. This is the wire that will be carrying low current from the ignition circuit to the coil winding of the starter relay. It’s, therefore, not very thick.

How to replace a starter solenoid relay?

Then, remove the faulty starter relay by unbolting it from the engine bay and replacing it with your new relay. Next, identify the wire from your starter solenoid and connect it to one of the big terminals of your new relay. Additionally, you can join it to either of the big terminals as they can all accommodate the high current from the battery.

Where does the battery wire connect to the starter motor?

These are the cables that connect the battery to your car’s starting system. First, the red one connects the starter solenoid to its positive terminal. This wire is usually live so be careful when handling it. Then, a black or greenish-yellow cable connects the starter motor to the battery’s negative terminal.

What gauge wire is used for starter relay?

The output terminal and the battery connection are usually much heavier than the other terminals on the relay, since they conduct so much more current between the battery and the starter motor. They might be 10 gauge or larger wires depending on the vehicle and starter size.

How to tell if starter relay is bad? Well, it is one of the major but often neglected components of the ignition system. It rarely breaks down due to not having many moving parts. But, when it does, some bad starter relay symptoms will make you aware of the problem. A failed starter relay means the car may not start at all.

Do I need a new start relay?
