Repairing a 1983 V65 magna Instrument panel
I'm sorry, I'm quite sure this is NOT what you're wanting to hear, but both of those PCBs are 100% FRIED. The char marks &amp; molten plastic tell me that at least 90% of the components on those boards have far exceeded all thermal tolerances. You're going to have to simply replace the whole thing.

Best case scenario: It looks like you might be able to salvage a few of the resistors &amp; maybe the 2 switching diodes I see (but all of them together would cost less than $1 to purchase new...all the expensive parts are destroyed).

--EDIT--

Make that 4 diodes (the glass ones, the plastic one is dead).
Also, as a note, "Z" looks like what used to be a voltage regulator IC...now it's just the component that self-destructed in the most ostentatious fashion though.
