MF 8780 won’t unload

Tried to pick corn today, only got about thirty acres done the the unload control started acting up.

First you may have to had pushed the button twice to get it to kick in, then it would shut off about part way thru, then several times thru, then maybe would only run for twenty seconds, now won’t start at all. 

Have narrowed it down to the unload engage module on the lower right corner of the fuse/relay board. So far parts guys are claiming it’s not available and you have to update the board to a newer one and a new module, I can’t even imagine what an obscene price that will be.

Pretty sure its the module though, the sealant is cracked on it and starting to fall off, this is the module thats held on with one little screw then unplugs.

We have a few junk yards in the area but none real big on MF, wondering if anybody had a salvage yard near them with a few MF 8780’s sitting in it?

If nothing else if a replacement unit fixes the problem even if temporarily, then we know dropping the money on a new board isn’t a complete waste of $$$. Hate to spent too much though as looking to trade it in on a MF9790 or 9795 at some point.
