I'll take a look at it when I return from the break. For now I will set the supply controls so they will not try to open S6. I am not sure if the s6 solenoid is still connected to power.</div>

This is a different issue. Neither the supply nor return coil/solenoids respond to the controls for Sector 6, although they work fine when connected to a different sector's controls. </div>
<div class="x_x_elementToProof" style="font-family: Aptos, Aptos_EmbeddedFont, Aptos_MSFontService, Calibri, Helvetica, sans-serif; font-size: 12pt;">
The sector 6 controls also fail to operate other sectors coil/solenoids when connected to them. The associated 're-circ-it' circuit breakers appear to be okay. However, we're only getting ~95v out. </div>
<div class="x_x_elementToProof" style="font-family: Aptos, Aptos_EmbeddedFont, Aptos_MSFontService, Calibri, Helvetica, sans-serif; font-size: 12pt;">
We'll need to revisit this after the break.</div>

I changed the set point to get the MFC to respond. It closes when set to 0 and opens full when set to 1. Sounds like the the supply solenoid may be the issue.</div>

If you have to replace the solenoid, I would use the coil that is on the valve if its not bad. Just make sure you replace like for like.</div>
