How to Read and Write Electrical Schematics Part. 1
This stuff is not as hard is it may look. Once you look at them a couple of times and follow what they do, it is actually really easy. I figured this stuff is pretty relevant with doing alot of the electrical mods in the how-to forums.
Application: Any electrical modification done to your car or otherwise.
Symptoms: You start looking through some of the great How-tos but all those funky diagrams are really hard to understand how the hell your supposed to do it.

If you can read, you can understand this stuff with a little studying.

Like I said this stuff is really easy, just read the symbols and follow the direction of the circuit. Afterward, test yourself on the 2 examples below.
The first 4 diagrams are references to some basic component symbols that are commonly used, but this by far not a comprehensive list. Just enough to get started.
Figure 1
Is an LED light powered by a battery. Some terms that are commonly used with ciricuits is "open" and "closed". For example you can have a normally open switch or "NO" switch which means the current is cut or off. The opposite of this is normally closed or "NC" which means the current is live or on. Each of the components have a letter associated with them like "R" = resister, "BT" = battery, "F" = fuse. The diagrams above show the letter for the component in the upper left corner of each one.
Figure 2
Explains how a each part of the schematic is named such as what a "Junction" is. Look for the others.

- Wallow in self pity, go into a corner and start sucking your thumb.
- Educate yourself and start understanding how to do some of the really cool mods in the How to section.
