    Transformers are one tough mother. I once pulled one out a field that I left out for over 5 frigid New England winters and fired it right up in a taxi (true story).

    However, I’m confused by what’s going on with system 80b transformers, but perhaps someone can clue me in.

    I have a genesis I’m working on, and I noticed 4.9 volts. I have a steady +5 at the power supply, so what are the transformer volt used for?

    I wanted to cross check that the volts were correct with my bounty hunter and accidental slipped and touched the 40 the one next to it that clearly wasn’t 40, a small spark happened and now there is no 40....

    Is there a way to get the 40 back? Did I really just brick the transformer that easily? And what are the significances of these volts like the 4.9 on genesis. Bounty hunters read 5.2

    Thanks

    Unrectified voltages will always be off target slightly from the expected rectified DC voltage. I don't usually worry about it unless it's +/- more than 10% or so. The rectified DC voltage should be greater than the raw AC voltage from the transformer because the AC waveforms are combined.

    As for the missing voltage, have you gone through and checked all the fuses with a multimeter, and not just visually?
