How do you wire a starter relay to a car?

If there’s another small terminal, connect the other small wire to it. In case the starter relay has 3 terminals only, connect the thin wire to one of the bolts that secure the relay to the body of the car. Or just anywhere, provided it touches the casing of the starter relay.

How do you connect a starter solenoid to a car?

Find the thick starter solenoid cable. Connect it to one of the big studs or posts on the relay. Secure the connection by tightening the mounting bolt. It does not matter which big terminal you connect the wire to since starter relays do not have polarity.

How many terminals does a starter relay have?

Some starters will have three terminals only, two big ones and one small terminal. This is no problem because one of the two small terminals is always the ground wire to connect to the car’s body. When the starter relay is mounted, the bolt securing it acts as the earth connection.

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 do I start my car with a starter relay?

Before beginning, make sure the cable connected to the positive terminal of the battery is disconnected and securely out of the way to avoid electrical accidents. Start by mounting your starter relay in the appropriate position.

Can a starter relay be connected to the ground wire?

This is no problem because one of the two small terminals is always the ground wire to connect to the car’s body. When the starter relay is mounted, the bolt securing it acts as the earth connection.

How do you hook up a starter to a starter switch?

First, connect one of the large terminals directly to the hot wire from your car’s battery. Then, affix the other large terminal to your starter. Secondly, connect one of the small terminals to your starter switch, with the other one connecting to either the ballast resistor or ignition coil.

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 size wire for starter solenoid relay?

Larry, by the smaller one, you mean from the remote relay to the solenoid? 10-12 gauge should be plenty as the wire is only powering the solenoid on the starter. Wire from battery to cutoff switch to starter should be upgraded to 2gauge from kits 4 gauge.

What gauge wire for starter wire?

Wire from battery to cutoff switch to starter should be upgraded to 2gauge from kits 4 gauge. Ford specifies 12 gauge for the S wire in their mini starter kit. dont forget battery to frame & engine to frame #2 cables on negative side.

How many amps can a starter wire handle?

If you have a shorter power wire to the starter, you will have less voltage drop. Or the longer your starter wire is, the larger the gauge you need to keep the voltage drop to a minimum. A 4 gauge wire can handle 135 amps, but at that load, shouldnt be bundled with other wires.

What size wire do I need to jump start a relay?

The ground side of a relay will only need to have around 300 milliamps to make the coil energize.Easy man, easy. Terminal 85 is battery power also. (use a smaller gauge wire for this little jumper from terminal 30 to 85.)
