Where is the ground wire to the starter on a 1996 corolla?
There is no ground wire. The casing of the starter itself is considered the ground. Ex. If you take a battery and use jumper cables to touch the positive lead to the wire terminal on the starter, and then touch the negative terminal to the metal casing it will spin the motor.

How do you know which terminal on a starter is positive and which one is ground?
THE LAST ANSWER IS CORRECT OR MORE TO THE QUESTION THERE IS NO GROUND WIRE ON A STARTERFollow the wire. One will go to ground, one to hot. Most starters are marked with a + (positive) and a - (negative) on the terminals themselves,just like your battery. Usually the larger terminal where the battery cable connects to the starter is the positive terminal. .On a most starters both posts are hot(+) and the casing is grounded(-) .Usually the bigger post is a direct wire from the battery and the smaller post is a remote wire from the starter switch.Follow the positive battery cable wire (+) to the other end, that should lead you there. Because it will be connected to the starter solenoid. Please take note, a solenoid mounted on a starter has no ground wire, but a solenoid separated from the starter and mounted on the firewall does.
How to replace battery cables for 1998 Nissan Frontier?
The negative( black wire universal symbol for it is -) cable is a single wire connected to the frame on the passenger side. Step 1. Remove the negative terminal ( marked " - " on the battery), then remove the positive ( marked " + " on battery) Now that the battery has been disconnected , remove the two small 10mm bolts on the battery stay/holder. Remove battery holder, then remove the battery, it will give you more room to work with. Step 2. Follow the negative wire to where its grounded to the frame remove bolt, and clips that hold it in place. Once you have the wire free, measure old wire, cut or have wire cut at auto parts store, replace terminals and reinstall The positive cable (Red wire or wires the universal symbol for it is + ) is a little trickier than the negative. You have two wires going into the terminal that is bolted to the battery post. The first wire ( heavy gauge) goes to the positive side of the starter. The smaller of the two wires goes to the positive side of the alternator. This wire has a red cap covering the post/terminal on the alternator. Check with an automotive parts store for the proper gauge wiring that should be used. 1998-2004 Nissan Frontiers have proprietary battery terminals that are not easy to change or to convert to a standard battery terminal. You will have to remove the plastic casing covering the positive & negative wires. You will notice that once the factory terminal is removed, you will see two flat copper plates,they are crimped to the two positive wires. You will have to cut and strip the wire, using help from the local auto parts store find the appropriate terminal. Reinstall, reconnect the battery.
Why were negative numbers written in black?
Because the colour of a "negative wire casing" is black, hence the reason why negative numbers were written in this colour :)
How to Install a New Car Battery?
Install a New Car BatteryInstalling a battery for your car is a very easy task that can be done with a few simple tools. Anybody with a little mechanical knowledge can perform the task.Battery Placement and SecurityBegin by placing your battery carefully onto the battery platform. Make sure the platform is clean of debris so that the battery sits level. Then take the battery bracket, which is used to hold the battery in place, and tighten it down using a socket wrench. Now that the battery is securely held in place, be sure to check that you have everything else in place before connecting the battery.Connecting The BatteryBefore connecting the battery, it's a good idea to place a protective rubber casing over the connection so that it sits between the battery cable and the battery casing. This will prevent any corrosion of the casing to occur. Start with the positive battery cable. Place it over the terminal connection until it is all the way down and the terminal is sticking out above the terminal. Tighten the cable securely to the terminal with a wrench. Repeat the same procedure with the negative battery cable and you will be good to go.
How do you replace a battery cable on a Ford Windstar?
The positive cable is normally red and the negative cable is black. The positive cable fastens to the battery and the starter solenoid or relay. The negative cable fastens to ground on the engine block. Some manufacturers use a negative cable with no insulation. Sometimes the negative battery cable may have a body grounding wire to help assure that the vehicle's body is properly grounded. NOTE Be sure that a replacement cable has sufficient slack to allow movement of the engine on its mount. The ground cable (usually the negative) should be disconnected first. This is a good habit to follow whenever doing major repairs. Loosen the battery negative terminal clamp. Spring-type cable connectors are removed by squeezing the ends of their prongs together with wide-jaw, vise-gripping, channel lock, or battery pliers. This pressure expands the connector so it can be lifted off the terminal post. For connectors tightened with nuts and bolts, loosen the nut using a box wrench or cable clamp pliers. Using ordinary pliers or an open-end wrench can cause problems. These tools might slip off under pressure with enough force to break the cell cover or damage the casing. Always grip the cable while loosening the nut. This eliminated unnecessary pressure on the terminal post that could break it or loosen its mounting in the battery. Use a terminal clamp puller to remove the negative cable. Prying with a screwdriver or a bar strains the terminal post and the plates attached to it. This can break the cell cover or pop the plates loose from the terminal post. Track the cable to its end and unbolt it from there. Loosen the battery positive terminal clamp. Use a terminal clamp puller to remove the positive clamp. Track this cable to the starter relay or solenoid switch and unbolt it from there. After servicing the cables or battery, install the positive battery cable by reversing the procedure to disconnect it. Then install the negative cable. Do not overtighten any nuts or bolts since this could damage the post or connector. Before attempting to reinstall the old terminal clamp, clean the terminal clamps and enlarge their holes using expanding pliers. NOTE Never reverse the polarity of the battery connection. Generally, all vehicles use a negative ground. Reversing this polarity damages the generator and circuit wiring. Coat the terminals with corrosion preventative spray, then check the job by starting the car. You can also coat the connectors with petroleum jelly or battery anticorrosion paste.
How do I change a garage door light bulb?
To change the garage door light bulb you need to remove the protective casing. Once you have removed the positive casing, you can replace it with a new one.
How do you know if your starter motor has broke?
If you are certain the battery has a good charge and the solenoid is good, then your last choice is to remove the starter for a bench test. Hold it firmly on the bench and apply 12 volts from a battery charger for a second or so. Hold negative on the casing and touch pos. to the main terminal.
How do I change a motorcycle battery?
First you have to locate the battery on the motorcycle. Mine is under the seat so I have to take the seat off to get to it. Use a screwdriver to loosen the terminal bolts and remove the wires. Pull the battery out of the battery casing and replace it with the new battery. Be sure to connect the negative and positive wires to the correct terminals. Replace the seat or battery cover and you are all set to ride. I am a girl and have been taking care of my own bike for 15 years. See you on the road.
