How to find positive and negative DC wires?
Whichever wire is connected to your multimeter’s red lead is positive, and the one on the black lead is negative or ground. This multimeter is dialed in to measure up to 20 volts DC, appropriate for most AC adapters. You can use the red and black leads to find positive and negative DC wires.
How can I tell if my voltage regulator is faulty?
With your car still in park, slowly press on the gas until your car reaches 1,500-2,000 RPMs. Read the output on the multimeter. The regulator should cap the output of your battery at around 14.5. If the voltage reads over 14.5, it probably means that you have a faulty regulator.
What kind of wire has a negative voltage?
Any wire that gives you a negative voltage with a ground wire connected to the black lead is negative. Alternatively, any wire that increases the voltage when you connect it to a positive wire is also negative. For example, some power supplies will output -5 and -12 volts.
How much does it cost to test a voltage regulator?
This meter will be able to read the voltage running through your battery and will indicate whether your regulator is working properly. A multimeter is often much less expensive than other complex diagnostic tools and can cost from anywhere from $14 to over $100. Open the hood of your vehicle.
