Lost power to emergency buzzer

[Dmaxx85]

Hey guys we were working on getting rid of the emergency system and buzzer on our 2002 international bus and in the middle of it all we lost power to the buzzers, interior lights, all three heaters and the dash fans and who know what else at this point[emoji30] we’ve been looking for blown fuses and can’t seem to find any.
Any suggestions on where to look and what could have happened????
Thanks

All the things you described you lost power to should be on the fuse panel that’s only on when the bus is on or the key is set to appliance power (turned to the left). This panel should be the one on the left, so is it still connected and if so is the wire carrying current? Did something happen with the battery wires?

Yes that’s correct these items only come on when the key is on or running. I will take a look tonight at the fuses coming off the battery but the battery wires seem good the bus still runs
