Immobiliser Draining Battery

Hi, Got a tiger 800 xrt 16 plate. The battery is flattening after 5 days and mechanic has traced it to the immobiliser, when he takes the fuse out the drain stops, any ideas why this is happening, could it be one of the relays which the fuse affects to the dash as has been suggested. Thanks in anticipation. Daryl.

 

Its a brand new battery.

 

It is a new battery, fully checked, correct one.

 

5 days if not used, we were coming to the conclusion to use a optimate, finding what is draining the battery could be a long and expensive option, thanks a lot for your help and advice. Daryl.

 

I think it's all sorted, someone walked into workshop and while talki ng to James about my bike noticed a light blinking under topbox plate, turns out a datatool tracker had been fitted which I didn't know about, and was drawing a constant 4ma, perhaps the battery in it was dead so was constantly trying to charge up. Tracker now disconnected so hopefully problem solved. Thanks for the help peeps.
