Electrical System Testing
Electrical System Testing

When it comes to electrical system testing, it can be one of the most frustrating issues.

Everything from dreaded battery dramas to faulty switches, relays, fuses, sensors, battery, starter  and connections.

So, Many functions that operate in your vehicle require a sound electrical connection.

So, before any electrical system testing is done you must start with a fully charged good battery.

All electrical circuits require voltage to operate the components connected to that circuit. So if there is no voltage, there is no function. The first order of business when doing electrical testing, is to check for the presence of voltage at the load point in the circuit.

Finally, If you are having a electrical problem in your vehicle the first place to start is in the fuse box. Many things can indicate you have an electrical problem with your car. Every electrical circuit requires a complete circuit to operate.
