Hey, so i have a 2002 C32 I've been diagnosing a no crank issue on, and decided to replace the front SAM with another from a 2004 c32. Well I replaced the SAM and the car powered up normally until i went to turn the key to the start position, then there was a small pop sound and the car is now completely dead. nothing is powering on whatsoever. Battery is good at 13.3, I've checked all the fuses in the front prefuse box, pulled the Sam back out and checked the fuses(haven't checked the relays yet) I even looked at the circuit board and looks intact. any ideas? there isn't a master fuse for these cars right?

I believe there is a pre fuse box that feeds all of the power

yea I've checked the pre-fuse box already and they all seem to be good
