Electrical short... help appreciated

[snoop32]

Hey all, I have a 2007 v8 vantage coupe. I had it on a Ctek 7002 trickle charger and when I took it out this morning, nothing on the dash worked. Speedo and rpm is frozen. Lights, radio, AC all work… just the dash is dead. I googled it and it seemed like the roadster folks had this issue with their CRM but mine is a coupe. I located up the cabin fuse and noted that fuse 46 was blown. I replaced it and it blew immediately. Any ideas?

FYI when it was on a trickle charger plugged in the trunk and we’ve had lightning storms/power surges so maybe that was the culprit?

Any help/input is appreciated

prob the crm a lighting surge would be dealt with by the ctek. trace the circuits that are fed from that fuse

Mine is a coupe. Is there a CRM equivalent? Thanks

F46 in the CEM is:

Driver Information Module
Master light switch
Glove box relay
Master lock switch
Battery Off switch
Boot release switch
Speaker-switch
JBFB-R7
Centre console module
Bluetooth module

Thanks Ridds. Any pointers on how to narrow it down? Should I just start unplugging the switches and connect them back one by one to see which one blows the fuse? also, would it be more likely a switch is causing this electrical short or a module? (I would think module?)

very likely a poor module...

Quick update. I took apart the dash and disconnected the instrument panel and viola, the fuse isn’t blown. This leads me to believe there’s an issue with the dash panel. Does anyone know where I can get it repaired?
