More info would be helpful...what kinda of problem are you having that leads you to believe it is grounding? When its electrical, most of the time the problem you are having will lead you to it.

In some cases you can find it by ear. (Note: this doesn't always work) Turn the car to on (not started but all the way over like it is about to start). Listen for a high pitched whine. If you don't hear one, try turning on your radio but turn the volume all the way down. If you still don't hear one, turn the radio off, turn the AC on but at its lowest power...continue until you hear that high pitched whine. If you run through everything and still aren't hearing it, you can try putting the car in that same "On" position and hop out of the car. Listen under the hood, back toward your gas tank, and everywhere in between. Bottom line, is if it is grounding out, there is a decent shot that it will be making a high pitched whining sound. Be forewarned...it can be rather quiet and hard to catch if you aren't really listening for it...

Again...any other suggestions will be based on what problems you are having.

Windshild wipers wont work on 94 explorer can hear a clicking sound when the blades should being going. Varries with speed and intermintent. Could it have something to do with the relay?

The clicking sound is your relay sending a pulse to your wiper motor. Get a test lite, unplug your wiper motor and check all the wires coming from your switch for 12v power. The black wire is ground, you can use that to ground our test lite. If no power is found then attach your tester to a solid known ground on the vehicle and retest again. If you find power then you have either a bad ground or a bad motor. Check the motor by running a hot wire off your battery and a ground to the the vehicle. If your motor works then you possibly have a bad ground.


How do you ground earth a car?

Unless it is a stationary vehicle where you can stick a spike into the ground, you can't ground earth a car. Aside of a chassis ground, the closest you can get to an earth ground is through the vehicle's tires, which ground you in the event of a lightning strike to the vehicle.

How do you find a bad ground?

To test for a bad ground I use a jumper lead with alligator clamps at each end and ground the device that way. To find the actual problem you need to find the point where the wire actually is attached to ground and check the circuit there. If the problem is not at the ground point It may be better just to run a new wire than fight with it. Using a voltmeter, attach the leads between the negative battery post and the negative connection of accessory in question, then attempt to operate accessory. If the meter reads more than .5 volts, the ground is bad.

What do you do if you are outside during an earthquake?

Try to find an area where there is nothing above you and then get as low to the ground as you can. But if you can, try to get to a vehicle, because that will offer you more protection from falling debris and ground collapse.
