Making sure that the gauges on an automobile are functioning properly is one of the easiest and most important ways to ensure the long-term health of the vehicle. If the gauges are not working as they should be, there may be other problems occurring that the owner is unaware of. Here are some troubleshooting tips to correct any issues with Auto Gauges in Phoenix AZ.
A coolant gauge that does not read at all or reads erratically can be caused by three things. If the connections are loose or dirty, simply clean them and re-tighten them to solve the problem. The sending unit may be defective. To check if this is the case, disconnect the wire that leads to sending unit and ground it. If the gauge registers, it is time to replace the sending unit. The gauge itself may be defective. To check if this is the case, disconnect the wire that leads to the sending unit. The gauge should read cold with the ignition on and hot when the gauge is grounded. If not, replace the gauge.
An ammeter gauge could have two things wrong with it. If the ammeter shows a charge, then the connections are reversed on the gauge. To fix this, simply disconnect and reconnect the wires in the proper sequence. If the ammeter does not move at all, either the connections are loose, or the gauge itself is faulty. Tighten the connections, and if this fails to solve the problem, it is time to replace the gauge. If the ammeter shows a discharge, nothing is wrong with it. It is working as it should.
If none of the Auto Gauges in Phoenix AZ are operating, it is most likely due to a blown a fuse. Simply replace the fuse, and all should be well. If all of the gauges read as low or read erratically, the instrument voltage regulator is in need of replacement.
