Signal injected the RF module, no 45 MHz output. Discovered there was no -15V on the control cable. Inspected the power supply in service building W1, found a blown fuse. Replaced 1 A fuse. Signal injected the RF module, output looks good. Wire sums are balanced and the gains are equal.
Started mild bake of line to pump cart before opening valve
