Default Control board not commanding FAV to open ... not true

Hello all,

I recently ordered an hfs4 kit from Jeff at howerton engineering. The kit was functioning perfectly for a few days but last week the kit stopped spraying.

Jeff and I troubleshoot it down to the controller board. There are no clogs in the system. The FAV operates perfectly when supplied with 12v. The control board has no voltage across the FAV outputs when in SYS. The FAV wiring lead is continuous. There are no scorched connectors, traces of components.

What do you guys think could be the issue?

Jeff suggested I email aquamist about it but while I wait on a reply I figured I would lost here.
