just drove home to grab some gear and now it wont start
no clicking from the starter motor what so ever
but the dash lights go dim when i try to start it

I have checked the fuses in the drivers foot well and there all good
same with the big fuses in the engine bay
I have also checked the voltage on the battery and its at 12.5
is there any hidden fuses i am missing etc?
any help would be greatly appreciated
