Auto Electrical System Help
Many parts rely on the electrical system of a vehicle to power them so that they function properly. Several tools can assist when trying to find and fix auto electrical problems. A voltmeter, an ohmmeter or a simple test light can make the job of locating electrical issues within a vehicle a lot easier and safer.
Fuse Help
Although replacing a blown fuse can sometimes be enough to fix auto electrical system problems, the real issue is often what caused the fuse to blow. Either way, replacement fuses should never exceed the capacity of the blown fuse being replaced as the circuit will not be able to handle this.
Relay Help
A relay is a switch that brings voltage to a circuit while also lowering the amount of wiring needed within the circuit. Jumper wire can be used to bypass a circuit breaker to test a circuit. This same method can be used for a relay as well; if the circuit works after bypassing the relay, then the problem indeed lies within the relay.
Circuit Help
When a circuit is dead, the load point is the first place to look; checking the voltage here with a voltmeter can help to identify the problem. Ground connections could be no good if you find that there is voltage in the circuit. If you find the "hot" wire void of voltage, then the problem is likely due to faulty wiring.
