The fiberglass is the material inbetween the copper layers. If it's burned away, what are you touching? A copper trace?

[impactair]

If you look in the pictures you can see It's a section of exposed copper, like a super wide trace, right under where the capacitors were. That is conductive with the inductor, as well as the speaker terminals. The black coating melted away and I believe it is a wide trace. But I am not sure if it should be conductive with the inductor and the speaker terminals.

[Perry Babin]

It's likely a copper conductor (trace) that's connected to both the inductor and the speaker terminals. That trace passes the audio signal from the inductor to the speaker terminals.

The insulating/protective coating on the circuit board (that burned away) is called solder mask.

[impactair]

Ok, so It allows larger amounts of current to pass. I still read a short from one mount hole to the other where the capacitors went. Without the capacitors installed should'nt there be a break in the circuit?

[Perry Babin]

Are you reading the same thing that you read across speaker terminals?

You shouldn't use the term 'short'. Put the meter on resistance/ohms and post what you see on the meter's display.

[impactair]

Your right I confused myself. I read the same as I did across the speaker terminals. 4.7 ohms. I have the capacitors on order. when I get them in the board that should change the resistance across the terminals right? I apologize for the confusion, I have never seen a meter read this way.

[Perry Babin]

What resistance do you read when you touch the probes together?

[impactair]

000.0 in ohm's

[Perry Babin]

Remove the inductor to see if the resistance across the terminals changes significantly.

What make/model meter do you have?

[impactair]

I have 6 ohm's across the speaker terminals. 000.0 across the inductor, and 20m ohms where the inductor was. I have a Radio Shack 22-812 Digital Multimeter with PC interface. Sorry I took a bit I had family over.
