Disconnect the other things as already mentioned.

Your first comment for a newbie is typically "should have bought a Honda". That is the opposite of helpful.

He said he pulled the fuses and no help now he has to disconnect the unfused items.

Cliff Claven is the bar know it all; proudly spouting facts not fiction and boasting about it. He's not spouting off random guesses which is how the term has been used above.

Everybody can just let that sink in.

Meanwhile I will answer based on any feedback I get from the OP with a grand total of two posts.

There is either a short in an unfused powered item or OP missed some fuses say under the floor in front of the spare tire or in the back right in front of the right tail light.

The b+ terminal uses a 19mm head and will disconnect the battery from the alternator and starter in case there is a short in one of them.

With very little feedback to go on we can only make small steps but like mentioned this situation has come up 20 or so times in the 6 years I've been on xo and only once did the owner have to resort to outside help. Basic electrical troubleshooting is the proper course at this time
