Fuse of the 'original' inverter California 2005: where

[carl4]

Hi specialists,
because the 'original' inverter' don't load the batteries when my California 2005 is hooked up I want to use external inverter.
But how I can disconnect the 'original' inverter ( which cables are to disconnect on the battery under the drivers seat)and what is the number of the fuse of the inverter.
Thanks for your help and advise,
Greetings
Carl
