In a digital circuit, power supply voltage levels are constrained to two distinct values – “logic high voltage” (called LHV or Vdd) and “logic low voltage” (called LLV or GND). The GND node in any circuit is the universal reference voltage against which all other voltages are measured (in modern digital circuits, GND is typically the lowest voltage in the circuit). In a schematic, it is often difficult to show lines connecting all GND nodes; rather, any nodes labeled GND are assumed to be connected into the same node. Often, a downward pointing triangle symbol, is attached to a GND node in addition to (or instead of) the GND label. The Vdd node in a digital circuit is typically the highest voltage, and all nodes labeled Vdd are tied together into the same node. Vdd may be thought of as the “source” of positive charges in a circuit, and GND may be thought of as the “source” of negative charges in a circuit. In modern digital systems, Vdd and GND are separated by anywhere from 1 to 5 volts. Older or inexpensive circuits typically use 5 volts, while newer circuits use 1-3 volts.

In some circuits, there are virtual grounds, which are nodes at the same voltage as ground, but are not connected to a power supply. When current flows into the virtual ground, the voltage at the virtual ground may change relative to the real ground, and the consequences of this situation must be analyzed carefully.

When multiple components are connected in parallel, the total current is the sum of the currents flowing through each individual component. These statements are generalized as Kirchoff’s Current Law (KCL), which states that the sum of currents entering and exiting a node must be zero.

Note the location of each wire on both sides of the original connectors and identify them with markings before you cut off the old connector.

By Cyrielle Marjolaine. Car Wiring. Published at Saturday, December 30th 2017, 12:48:04 PM. Plan out your wiring. Choose the path the wires will follow. Choose the locations of all of your switches, gauges, ignition box, battery, and charging posts. If your past layout was deficient, now is the time to rethink the entire plan.

The size of the fuse wire is the thinnest that can carry the normal current of the circuit without overheating, and it is rated in amps.

Always solder the terminal where the wire end is installed. Never crimp the terminal and expect the wire to stay there forever. It won’t.

You have a lot of time in the off-season and for your team, designate a qualified person to be in charge of the wiring and the process of rewiring the car as well as being the pointman for mid-season troubleshooting of electrical problems. Don’t assume everything will be OK for next season with what you have, take the effort to make sure. It’s so much fun when things don’t go wrong.
