It's a code 122, I just received the schematics I purchased and they make a lot more sense. The one I got online for free was missing a lot of missing keys to this puzzle and it confused me.
I was wondering if someone would be kind enough to educate me on what the purpose of a specific component is? The pictures show what i would think is an isolator? It's held in place by the metal of the chassis and formed of some type of thin black material. It has several pins protruding from it that have various resistors and wires soldered to them.
In the photo you can see that some of it is burnt out and when I plug in the radio this area shorts out (I can see tiny sparks and sizzles but I only plug in the radio for a quick second - please don't yell at me)
My question is, what is it for? Are each of the pins carrying power and this material is keeping them from contacting the chassis ground? Is that why I'm getting sparks? It just seems odd because some of the resistors and other leads that are soldered to it end there. There's nothing else soldered to it so It makes me think that it's supposed to be grounded there?
As you can probably tell by my question, I'm VERY new to this and probably not qualified but you've got to start somewhere I suppose.
Enough chit-chat, here's the pictures and hopefully someone with answers?
