Does the big 3 upgrade really work?

The Big Three wiring upgrade

A good, cost-effective improvement is to perform the "Big Three" electrical upgrade. This will vastly improve your vehicle's electrical system, allowing more current to flow easier to all components.

What does R and S mean on a starter?

The "S" stands for Start, and the "R" stands for Resistor, I believe. The S terminal is wired to the start terminal on the ignition switch. If the vehicle is equipped with a neutral safety switch, it will also be in this circuit. Applying voltage to the S terminal trips the starter.

Can I use 4 gauge wire for the Big 3?

Your wire upgrade should be a minimum of 4 gauge but 2 gauge or 1/0 is always better. ... The next wire that need to be upgraded is the ground wire from the battery to the body of the vehicle. The ground wires are especially important. You will add a large wire from the battery negative post to the body of the vehicle.

Does positive or negative go to starter?

Where does the positive wire 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 is the Big 3 wiring upgrade?

A big 3 upgrade will allow more current flow to all of your stereo components, improving your electrical system by ensuring more consistent voltage. This upgrade entails replacing the three main cables in your electrical system with 4 gauge or 1/0 wires.

What wire goes where 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. Often, a poor connection at one of the battery cables can cause the starter motor not to run.

What is the R for on a starter solenoid?

The "R" terminal is hooked up to a yellow wire which leads to the coil, which supplies additional battery voltage to the coil ONLY WHEN THE STARTER IS TURNING. This is important, because it tells us what the label "R" means. The "R" terminal is a RELAY terminal, which is switched on and off by another circuit.

What are the three terminals on a starter?

Typically, a starter-mounted solenoid has three terminals with three connections:

What fuse to use for big 3 upgrade?

fuse it with a 300A fuse...for longer runs of 1/0 you'll need a smaller fuse such as a 250.

What happens if wire gauge is too big?

using larger wire will not hurt anything or cause any overload. The larger wire will cost more, the pathway or where it has to fit, and the physical size of the connecting means (ie. the size of terminal or clamp it has to fit in), will all be determining factors in just how big is too big.

Can I use welding wire for big 3 upgrade?

For optimal conductivity, you should use copper wire (OFC) when doing a big 3 upgrade. ... Alternatively, you can buy copper/aluminum wire (CCA) or welding cable.
