Lost mind muscle connection

Hey man I have a serious issue (in my eyes). Nowadays (for the past year or so) I cant feel my biceps work...at all. I have gone down to 10lb dumbells for slow controlled curls of all angles and all that gets a pump is the lower portion of the biceps and mostly the biceps tendon. Basically all I get from any direct bicep work is a pumped and sore tendon in the ditch of the arm, I am fresh out of ideas as I have tried every thing imaginable (that I can think of). Slow and controlled with light weight, med weight and heavy weight, slow cable curls behind the head, nose breakers, front double bicep curls, laying cable curls etc...you get the point. Any ideas are definitely welcomed, thanks in advance. BTW I have super crappy biceps with short bellies and long tendons ie I can place 3 fingers between my bicep and arm ditch

What about after a heavy back day? Do you feel any bicep activation?

Virtually none there either, minor bicep pump but nothing crazy. Tried training bi's after back as well...I am leaning towards some nerve damage somewhere now

Sounds a bit strange, I would suggest some ART on the biceps to correct any scar tissue if present. Its impossible not to work the biceps muscle if you are stressing the tendon. You can try some controlled concentration curls with a slow negative.
