Upon investigation of ARC2, all of the fuses and relays were checked and all tested good. The on-level relays for the capacitor bank showed signs of possible failure and were replaced as a precaution, the relays were determined the cause of the supply not being able to turn on. The connections to those relays we checked after installation for continuity and tested good. Supply main power was turned back on and and the soft start and main contactors both turned on with no issue abling the supply to drive current. Supply was handed back over to OPS.

The following cavity histories have been updated:
2L10-7
Username: kerns
Date/Time: 07-15-26_16:02:31
RF Status: Bad
Tuner Status: Bad
Comment: Cavity tuner stuck and torque motor inop per S. Dutton SRF / Kerns AESRF. OPS bypassed cavity and hope it's far enough off resonance now.
Special Instructions: Cavity tuner will not turn. Leave cavity permanently bypassed. RD1 will be installed next maintenance
