The function of current limiting circuitry is to prevent damage to the IC when an overload is placed on the output of the regulator (the load impedance is too low). Without current limiting, the regulator would source excessive load current and destroy the pass transistor inside the part.

Ohm’s law states that the current through a conductor between two points is directly proportional to the potential difference across those two points. It means that more the resistance lesser current would flow. I=V/R This would apply to any component of a circuit. For example conductors would increase the current flow and the inductors would decrease it.

At the input jack ground I connect a single wire from the power supply ground. I like to use something with low impedance to do this, often silver wire. Also at the input jack ground I attach a single wire from the active circuitry ground also with a low impedance wire. In this arrangement, neither ground is contaminated with voltages from the other. An obvious question now is that if you provide power to something in the active portion of the circuit, will not the current end up in the signal ground. The short answer is yes. It is also unavoidable and generally rather small in magnitude and normally does not cause problems. An exception is in power output stages. The large amount of current involved can cause noise in the signal ground so I ground them separately to the input jack ground. Could you run separate ground wires from each place in the active circuitry that puts current into the ground path? Certainly, and it would be a type of "star" ground system. I find generally it unnecessary. I can achieve signal to noise ratios of -90 dBV in high gain circuits without going to that method.

If you have removed the body in preparation for installing a new one, you will now have easy access to all of the attachment points as well as the gauge panel and switches. At this point, you have a blank sheet of paper and can do anything that works best.

When this happens, see if there is a short circuit or a disconnection, then install a new fuse of the correct amperage rating.

These are the basics and may even seem obvious or intuitive to you, such as the wires and if they are connected. Whenever you determine your specific field of electrical engineering, you may see more complex diagrams and symbols. You’ll learn also that different countries use different symbols. For example, of the two symbols for resistors above, the first one is used in the U.S., while the second is used in Europe. You will also learn about the various symbols used for switches, other power supplies, inductors, meters, lamps, LEDs, transistors, antennas, and much more.

We mentioned a catch, earlier. With these and other motor wiring variations possible, it’s easy to make a mistake. That drawing we said to follow could be wrong. Before you connect any wires, check the drawing carefully. That’s another reason to have that pocket motor wiring guide.

In addition, there needs to be a conductive path that provides a route for the electricity to flow. Finally, a proper circuit needs a load that consumes the power.
