Mid-limit, when it would go long intermittently for me.

I would think if its on only a hp function, you might have a loose or worn shear pin, or the hole for the shear pin is worn. On the HP function the arch is probably in the rear t bar eye?? My thought what I would be looking at.

If the rear eyes are toast or headed that way then it will go long on all passes not just hp.
I think a bent shearpin would only affect the front eyes as they would be obstructed on the hp rinse.
Might be the rear eye amp relay signal strength weakening too.
Good luck.

Must have been the day for eye trouble! Spent 3 hours last night troubleshooting t-bar eye. Depends how quickly you need to diagnose the problem and how often it's happening. You could swap front and rear amps and see if the problem follows the amp.

Thanks yep swapped out the amplifier with front eyes and yup it was amp .
