How do you read a schematic diagram without knowing what kind it is?

I've never read a scematic diagram and don't know what kinds there are so can you tell me how to read each kind?

1. Search on Google for schematic diagrams. Schematics are just the plans for just about eny device or gadget ever made.
2. I've been an electronics tech for almost 20 years now. Learning to read schematics takes time and is a crucial part of troubleshooting. There's people who have been in the field for years and are still not proficient at reading prints. Of course being able to read the prints does you no good if you don't understand electricity and electronics. But the first step to reading prints is learning the symbols. Here's a VERY good free intro to schematic symbols. It even has a little matching excersice at the end. Start here: http://www.wisc-online.com/objects/index_tj.asp?objID=DCE1902 Once you've completed the excersice, you can go to this link where they have a pretty good reference chart of component symbols and their function. http://www.kpsec.freeuk.com/symbol.htm These will get you started. There are many different kinds of diagrams (1-line, 3-line, Elevation, P&ID, Instrument Loop, Logic Flow, Schematic, Mechanical Integrity, Electrical, Conduit plan, Wire Schedule, etc, etc). Learning how to read all of them proficiently is quite a task and can't be explained here.
