4028 fan not working
My part cooling fan for T0 isnt working.
Wires have been checked for continuity using multimeter, no issue. White wire is in PA0 on toolboard and red and black is on 12v fan pin on BTT v1.1 board. black on the right and red on left.
I have had the jumper on v_in VDC for a while, not realising this is the wrong jumper placement. I now have it on 12V
Afraid my fan is fried. Is there a quick way to test this?
I also have been trying different solutions in the RatOS.cfg file to no avail.

The 4028 fan is pretty simple, if it is getting 12v and gnd, it will spin. The pwm line will only tell it to slow down; for safety of it isn't getting anything it will go 100%
