To check the engine ground connection, you connect the negative tester to a clean surface of the engine. Make sure to connect to the body ground connection. You then take the negative tester and connect it to the car body while leaving the positive one on the battery terminal.
The voltage should read 12.5V when the engine is not running and 14.5V when running. You set the multimeter to the appropriate direct current (usually 12V, but if installation is set at 24V, set to 24V) measure the voltage between the battery terminals. You can use a multimeter to check for grounds both when the car is off and on. Testing for grounds is a DIY job and can be done in these ways. If the dash lights stay on after the ignition has been switched off, it is prudent to check the grounds for disruption. This makes electrical gadgets in the car act haywire. When there is a bad ground, this flow is interrupted, and the current is forced to search for routes back to the battery ground. Related: What Does Battery Saver Active Mean? The ground generally keeps the flow of electricity in a closed-loop, to which every other electrical material in the car is connected. Having a bad ground in the car is the cause for many electrical issues in the car, like having lights go on when they are not supposed to. It is the connection of the car battery’s negative terminal with the car body and car engine. The grounds of the car are very pertinent to the electrical functioning of the vehicle. It can be done with a mechanic, and it takes about 1½ hours to 2 hours to change. On the other hand, one might have to change the ignition.Ĭhanging the ignition costs $80 to $300. It can also be the electrical part of the ignition that is malfunctioning, and most times, manipulating the key in the hole rectifies the problem. This happens when the car advances with age. One reason why the car’s dash lights would stay on after the ignitions switch has been turned off is that the ignition switch either is stuck in “on” mode or that even when the ignition switch has been switched off, the car is tricked into thinking it is still on. Most cars operate with a key that is put into the ridge and twisted, starting the vehicle. The ignition switch is the part of the car that starts the car. This is more of a feature than an issue to complain about. Note that the dashboard lights typically stay on for a few seconds on some cars after the ignition has been turned off.

This usually happens because of the car’s advanced age or if you recently have done some electrical work on the vehicle.
