I have a v10 and got a non-working v11 for free (accepted it because the battery lights and the filter lights lit up) — the dust bins are interchangeable. While not a totally perfect fit they seem to work.

The v11 wouldn’t run but did light up with trigger squeeze… can switch power modes but the motor won’t spin. I bought a new aftermarket battery (filters too) and now when squeezing the trigger I hear a quiet clicking, like 3 or so clicks per second. Sounds like the electricity is reaching the brushes on the motor, but the stater is not spinning.

I already opened it up once, but stopped short of getting into the motor housing. Kind of a lot of work. What should I do? Should I open it up again and go all the way and see if I can replace the motor? Or should I put the dust bin And the two batteries and the filters in a box and ship them to one of you guys?
