Haas VF5/VF9 TSC issues

Hello. We have a 2005 VF5 that is getting Precharge Failure alarm. I tried experimenting with the precharge regulator with no luck. I removed the regulator and went full line pressure and the TSC worked. Put a tool in the spindle, turned TSC on and it blew the tool right out of the spindle. I drilled the orifice out on the inlet side fitting on the precharge regulator, replaced regulator and TSC worked on a TSC drill bit (for 4 holes) and then it got a Tool Unclamped error. Reset machine and Tool Unclamped went away but Precharge Failure returned. Does the precharge regulator and solenoid control both the TSC and the TRP? Will too much pressure from the regulator cause the TRP to function incorrectly? Manually shuttled the precharge solenoid and it seems to be working correctly. Any ideas?

Also, we have a 2011 VF9 with TSC issues. When commanded the TSC will turn on (for a bit) then alarms out with 151 Low TSC Pressure. Also, when commanded and the TSC turns on, coolant pours out like crazy from the drain hole on the underside of the head. Any ideas?

Thanks
