short in ignition sw feed

2007 fleet truck
I have a .2 amp short that drains my battery.
When I remove the ignition switch feed fuse the current stops.
I am not sure where to trouble shoot from here.
Thanks

What is a "2007 fleet truck"?

Year, make, model, engine, transmission are the needed identifiers.

Identify the fuse by its reference designator from the owner's manual. If you do not have the manual, get one (see signature below).

Up to a 1/4 amp draw is completely normal until the battery saver circuit times out, some 30-40 minutes after the last door switch or the ignition switch changes state. Do not attempt to troubleshoot without taking that delay into account, otherwise you will waste significant time and effort.

Is the ignition switch turned to OFF? If "yes", unplug the ignition switch. Current draw gone? Replace the switch.

The ignition switch is the only thing on that fuse and all loads should be disconnected in the OFF position, assuming someone hasn't gotten the thing misaligned.
