FAQ
Q: How do I test a relay?
A: To test a relay, you need a multimeter. Set the multimeter to the ohm setting and connect the leads to the relay terminals. Check the resistance across the relay terminals. If the resistance is low, the relay is good. If the resistance is high or infinite, the relay is bad and needs to be replaced.
Q: How do I check the voltage of a battery?
A: To check the voltage of a battery, you need a voltmeter. Set the voltmeter to the DC voltage setting and connect the leads to the battery terminals. A fully charged battery should read around 12.6 volts. If the voltage is below 12 volts, the battery may be low or dead.
Q: How do I replace a fuse?
A: To replace a fuse, locate the fuse box in your vehicle. Open the fuse box cover and locate the blown fuse. Use a fuse puller or pliers to remove the blown fuse and replace it with a new one of the same amperage rating.
