How do you troubleshoot car electrical problems?

Check the ground connection with your ohmmeter. If the ground connection is good, the fault is inside the component. If there is no voltage in the “hot” wire to the component, then the problem is in the wiring. Trace back through the fuse panel (or relay or circuit breaker) until you find voltage.

What fuse causes car not to start?

If a fuse has blown in the starter circuit, then this could be a big cause for the car not being able to start. Other issues that could result from a blown fuse are broken or corroded wiring, as damaged wires to the battery or the starter can prevent a sufficient amount of power from reaching the starter.

What are the 3 major components of the electrical system?
