I think a page for a light chapter will cover you.
It won't hurt showing b2 tasks. Shows your versatility.
The CAA will also be looking for you to show experience in fault finding/trouble shooting and testing not just component replacement and inspections. Basically show experience within the scope of a LAE.
If you're B1 they will also be looking for electrical experience in fault isolation and repair ie crimping, splice, solider etc. I believe they are quite particular about that. I know a few folk who have had there application knocked back for not having enough of this.
Hope this helps.
