A small electromagnetic engagement coil consumes on the order of milliamps means just about any switch can activate it.

Every car's electrical system is composed of a wiring harness that connects various computer, controllers, lights, actuators, motors and switches. This electrical system is intergraded throughout the car to communicate with each part using a central computer which runs the engine or main electric motor. The battery is responsible for supplying power to the car while the engine is not running but in electric cars the battery does all of the work while powering the motor. High amperage circuits are designed with larger components to handle the load without failing. Common maintenance includes inspecting electrical connectors that are visible including the battery cables.

The most foolproof way to check a fuse is to pull it out of its receptacle and hook up a continuity tester to both blades of the fuse. But if you do this while the fuse is plugged in, you could get continuity through a path other than the fuse (for instance, both sides of the wire may be grounded when you check the fuse).

Before performing any work on your vehicle always be sure to disconnect and ideally, remove the battery from the vehicle. You should be able to take off the negative, then positive terminal clamps with a socket wrench, and then set the battery somewhere cool, out of the sun, and away from your work space.
By Salomon Herbert. Car Electrical Wiring. Published at Sunday, February 18th 2018, 00:40:01 AM. The most common problems with electrical systems are a short or open circuit. A short circuit is what happens when a wire has rubbed through to ground causing a fuse to blow. An open circuit is what happens when a connection stops working because of a broken wire or a bad conductivity. Low battery voltage can cause strange problems to the electrical components of the car due to insufficient operating voltage. Because of the construction of wiring connectors they can sometimes create high resistance which causes heat making the connector have an open circuit. When performing wiring repairs a wiring schematic is sometimes necessary to trace wires or locate a component.

By Salomon Herbert. Car Electrical Wiring. Published at Sunday, January 14th 2018, 00:24:44 AM. Only electricity really isn’t magic. Like most seemingly complicated things, automotive electrical systems are collections of very simple assemblies. And lucky for us, there’s no secret as to how these things work. It boils down to basic technique. Do a few things right and you’re assured many trouble-free years of service.

You may be lucky and just have a loose wire and banging just right on something might get it to fall back into place, but most times electrical problems are not that simple. Vehicles built in the 60s and 70s had very few electrically controlled devices as most things were controlled through a mechanical linkage. In the 80s and early 90s many automobile manufacturers started using vacuum controlled solenoids to operate small things like switches in the engine or the vents on your ventilation system. Since then, just about everything has become electronically controlled and regulated. Most of the electronics in your vehicle will last a very long time and never be changed, but when something does go wrong it can be difficult to pinpoint the problem.

Choose a spot on or near the firewall for the common ground point for the harness, and one point for a chassis ground on the negative side of the vehicle. This method gives you a single path to the negative side of the vehicle and provides a more effective ground. Use 10 gauge or bigger wire to connect the common ground to your chassis ground.
