how do I test electronic components?

Ok stupid questions. if this should be moved to kletts forum, move it.

I was told to...  
Quote:

"Junction test the transiters"



how do i do this? just see if it measures voltage on my multi-meter?

Quote:

"Just ohm the burnt resistors, and replace".



how do I "ohm" them?

Quote:

"Junction test the transistors and replace the bad one(s) or shotgun all of them".



shotgun means to replace em all without testing? and again.. junction test?

Quote:

"Check the i/o caps, or shotgun them".



i assume he means to check for leaking caps. how would i check and verify before and after voltages?

Quote:

"Put an AC voltmeter on pins 1 and 7 of the op amps and see if you have signal. If you do, look at both sides of the output caps. Compare left channel w/ right to see what's supposed to be there."



I think i can do this.

damm techies..


the only one I know is the "ohm test"....just see what kinda resistance (ohms) you get from the resistors..and if it's incorrect then you need to replace them....

Seeker-Ian:
so... send some voltage through the resisters, check the printed value of the resisters, then do the math?

I need a good web site for learning and applying this stuff.

I feel like such an idiot for not knowing this basic stuff.

You can find a simple color code chart here

I'll bet if you google some of the topics you're looking for, you will come up with some good info...

CKerian,

I hope you will not be offended by this but this is not the forum that you should be writing with this sort of problems.

I am sure some people wished to say this but I am prepared to be the bady in this instance.
