To ground a starter, you will need to connect the negative terminal of the battery to the engine block. This will ensure that the electrical current has a path to flow through and will prevent any damage to the starter.
- Disconnect the negative battery cable from the battery terminal
- Remove the starter solenoid wire from the S terminal on the starter solenoid
- Insert a small screwdriver into the slot in the B+ terminal on the starter solenoid and pry out the retaining clip
- Pull the B+ terminal off of the starter solenoid post
- Repeat steps 2-4 for any other wires or terminals attached to the starter solenoid

Bad Starter Ground Symptoms
If your car’s starter is having trouble turning over the engine, it could be due to a bad ground connection. Here are some common symptoms of a bad starter ground:
1. Starter won’t engage: If your starter won’t engage at all, it could be because there is no good ground connection between the starter and battery.
This can often happen if the battery terminals are corroded or loose.
2. Starter engages but engine won’t turn over: If the starter engages but the engine won’t turn over, it could be because the ground connection between the starter and engine is not good. This can often happen if there is corrosion on the engine block or other metal surfaces that thestarter needs to touch in order to create a good ground connection.
3. Engine turns over but car won’t start: If the engine turns over but the car won’t start, it could be because there is no good ground connection between the ignition system and battery.

How Do You Tell If Your Starter is Grounded?
There are a few ways to tell if your starter is grounded. One way is to check the continuity between the starter terminal and the engine block. If there is continuity, then the starter is grounded.
Another way is to check for voltage at the starter terminal. If there is no voltage, then the starter is not grounded.
Do Starters Need a Ground Wire?
If you’re talking about an automobile starter, the answer is yes. The solenoid that activates the starter motor has a large coil of wire wrapped around an iron core. When electricity flows through this coil it creates a magnetic field that moves the armature (a small metal bar) and engages the starter gear with the flywheel on the engine.
If there were no ground wire, the current would have nowhere to go and the solenoid wouldn’t work.
What Causes a Starter to Ground Out?
If you turn the key and nothing happens, it may be that your starter is grounding out. This can happen for a number of reasons.
One reason is if the starter mounts are loose.
The starters job is to provide the initial rotation of the engine to start it, so it needs to be securely mounted. If the mounts are loose, vibration from the engine can cause the starter to move and grind against other metal parts, causing a ground out.
Another reason is if there is excessive corrosion on either the starter itself or on the mounting bolts.
This can create enough resistance that when thestarter tries to spin, it grounds out instead.
A final reason this may occur is if there is something wrong withthe solenoid. The solenoid is what activates the Starter motor, and if thereis an issue with it, then power may not be getting to the Starter properly causingit to ground out.
Where Does Ground Wire Go on Starter Solenoid?
A ground wire provides a path for electrons to flow from the solenoid to the engine block. The solenoid is mounted on the engine and has two large terminals, one for the battery cable and one for the starter cable. There is also a small terminal for the ground wire.
The ground terminal is usually on the side of the solenoid that faces the engine block.

Conclusion
If your car’s starter is having trouble, it might be because it needs to be grounded. A bad ground can cause all sorts of problems, from a clicking noise when you turn the key to a complete failure to start the engine. Luckily, grounding a starter is a pretty easy fix.
All you need is a wrench and some wire.
First, locate the starter on your car. It’s usually on the front of the engine, near the bottom.
Once you’ve found it, look for a small hole with a bolt in it. This is the ground point.
Next, use your wrench to loosen the bolt.
Be careful not to remove it completely – just loosen it enough so that you can fit some wire under it. Once you’ve done that, wrap one end of the wire around the bolt and tighten it back down. The other end of the wire will need to be attached to something metal – either another part of the engine or the frame of the car itself.
That’s all there is to it! With this simple fix, you should have no more trouble starting your car.
