I purchased a used Hawkeye Swimspa 2012 used non functional, worked on by previous owner. I reinstalled new EL8000 M3, ML900 w 4 Jet lable, and 53680 expander board. 4 pump system. All pumps and systems function as they should except pump 4. Pump 1 two spd, pump 2,3,4 one spd 240VAC. Dip switch config A1 off 2,3 on 2,5,6,7,8 off 9 on 10,11 off 12 on B1 on 2,3 off 4,5 on 6,7 off 8,9,10 on 11,2 off. With the expander board connected white lead J95 240 VAC black lead J33 12 V and Exp I/O connected. When powered up systems start relay clicks and then expander board relays continous clicking, no pump 4 activity. continous clicking will stop when EXP I/O is disconnected. Have verified pump 4 is operational by swapping connections on main board pump 1. I'm missing some config and can't find any additional info on balboa site. Thanx in advance for any help.
Cheers
