using Lithium-vanadium or other rechargable cells in place of a super-cap can go boom.

transformer wire is just copper wire,
i wonder if there is a temporary short to N or gronud somewhere.
as for the toroid, unless it's some type of inductor to supress noise i have no idea what it does or why
can you test the board with something else like maybe a toaster as a load?...

you also need to remove and replace the JST VL connector.
maybe the transformer is bad - not sure why it would even be used.
that NOT the correct way to slow a motor - they should be using PWM drive or a triac circuit with trailing cutoff....

picture of the motor and it's spec plate/sticker would be handy.
if it can be done, i would run the motor directly for 5 minutes and have a clamp-meter over the wire to see how much current it's pulling.
i always like to test motors like that - it can give you an idea of bad windings or bearings....

the meter did it's job, it told you the cap was charged with several KV...

if you read out the atmel, what are the fusebit settings for the protection?
i suspect you need to write your own firmware.
it could be an interesting project to replace the mcu with an arduino to get more memory and a usb interface.
then start with getting the display going - or just replace it with an lcd
then your just switching motors and heaters....

about the windows problem.
maybe the encryption is enabled without a key,
so the data is unencrypted but all the headers and flags say it's encrypted!...
