Guys, long story. I have both newer 30 ft and 25 ft 1020 heads for my 2388. Yesterday the 30 ft's wobble box gave up so I'm using my 25 ft head. The last time I used it, I broke the left divider off going thru a muddy crossing. Fixed that today in a hurry...

Anyway, so I've checked everything, but when trying to use HT mode, the header raises straight up. It goes thru the calibration fine, from 2 to 56, but as soon as I hit the down button with the feeder on, it raises straight up and reads 2.5 on the HT display. It's almost like it has the height backwards, up is down, etc.

I also get the HDR S1 but only after doing the calibration, not when starting or anything.

I'm guessing maybe taking the POT off the 30 ft to see if that is the issue, but now that I've written this post I'm thinking its more the wiring or connector.  

Thanks
