Turn the car and the equipment that the fuse is a part of, off. After you do this, remove the fuse by gently pulling it out of its slot. Turn on your multi-meter and set the selector to OHMS, which is the setting that measures resistance. Now, put the positive and negative leads together and look at the reading being shown. Place one meter lead to one side of the tweeter and the other meter lead the to remaining tweeter terminal. Measure the ohms/resistance across the driver. If 3-8 ohms all is good. If you get no reading, then the tweeter is bad. You must disconnect st least one lead from the crossover to the driver for the test to be accurate. Step 4: Compare the Readings. Turn on the battery and the multimeter. Once you place the wires onto the battery terminals you shall notice the movement of the multimeter needle. You have to connect the multimeter at least 5 times and take 5 readings for the voltage. Now take out the average of all the 5. Checking with a DMM will show you the capacitor holds a charge (and can output x amount of volts,) but it won't really show you how much ass the capacitor really has. For instance, a nearly-dead AA battery will read 1.5 volts; So will a brand new one. The reason they say capacitors "don't work," is because they increase the overall resistance. Attach the charger's red clamp to the battery's positive terminal and the black clamp to the negative terminal. Give the clamps a little wiggle to ensure that they have a good connection to the.
