    54.6v 2a SMPS got shorted

    No, it was simply stated as a guide to save some time and effort. Everyone these days wants the "shortcut route to knowledge". Let someone else do the hard slog.

    Help Reading Schematic on My Old Sony AM/FM Mono Radio (Leaked Battery Acid

    You may likely need access to their machinery which would hardly seem worth while. Noise is usually suppressed at the source. You could of course approach any government body who might investigate any "unlawful" rf noise.

    Simple Wiring Question

    A trip to your local certification section at the vehicle inspection station might be worth it as well.

    Automatic transmission component

    I see 2 cables actually and then there is the mounting with a metal ring which could be a conductor secured to that as well. Apart from that, it is, just a black box, innards unknown. Way to identify would be to get a hold of the vehicle wiring which may resolve the mystery. Only way the...

    Bit of an old relic myself but still hear me ok and sharp as a pin....remember radios like those from when I was an apprentice....made my own valve amp set way back then too....Elvis never sounded so good. Soldering much better though....
