MK 179 Doesn't work anymore

Hello,

I made this kit a couple of weeks ago, it worked perfect.
Now, after trying to install it, my kit doesn’t work anymore

Even in the test situation, where it worked before, it doesn’t seem to work.
my question, can this kit break down when I install the coil the other way around or something?
Or are there other weak spots that can break down this kit?

Some more information:

I think it happend when I forgot to disconnect the power supply while I was re-connecting the coil.

@VEL337 Do you or a colleague know something about this??

Please check if the mainboard is still working: (by example erase all tags, check if relay/led is working).
If not, the Coil PCB can be damaged or disconnected ?

Hello, No nothing is happening…

even the LED isn’t flashing a little in standby (like it use to do)
He looks completely dead to me…

Check all soldorjoints again, trough this forum it’s almost not possible the see what the problem could be. Maybe a detail picture can help. Sending the PCB to us, is maybe to expensive …
