What do you have at the two bolts on top of the 1REC (T2 and A1). The one on the right is A1 and should be battery volts and the other (T2) should be half battery. If T2 is zero check for stuck directional contactor tips if it is battery volts check 1A contactor tips either one of these can also be bad 1REC. If A1 is something other than battery volts check power fuses and control fuses.
