If an ALTERNATOR out lamp is installed in the aircraft and is to be actuated by the R1224/R1224B regulator Connect the negative wire of the lamp to the LAMP terminal of the R1224/R1224B regulator.
R1224 Regulator Installation Instructions multi-Engine For both regulators, perform steps A thru J of the Single Engine procedure above. Choose one regulator as the Master. It can be either. Connect the OUT terminal of the Master Regulator to the IN terminal of the other Regulator.
Connect the Black wire to R1224 #1 (GND). Connect the Black wire to R1224 #1 (GND). Connect the yellow (Field) wire to R1224 #2 Connect the Blue (Field) wire to R1224 #2 (Field). (Field). Connect the Red (Power) wire to R1224 #3 Connect the Red (Power) wire to R1224 (Enable).
#8 (SENSE) and #3 (ENABLE). Jumper R1224 #3 (Enable) to #4 (AUX). Connect the Orange (Sense) wire to R1224 #8 For R1224 Rev B and earlier: Insulate the end of (SENSE) the A (Sense) wire and stow it safely.
Guide f There is a round connector on these Beechcraft regulators. Use two R1224 regulators set for 14V. Use the 12-1021 A round plug on a cable is plugged into the connector on the adaptor plate for mounting (which can be purchased from regulator.
Ensure that the R1224B internal jumpers are set properly for the aircraft voltage. See Plane-Pow- Remove old regulator. er R1224 Installation Drawing 12-1001. Ensure that the R1224 jumpers are set for 14V. Mark the wires on the Lamar regulators and See Plane-Power R1224 Installation Drawing disconnect them.
(which can be purchased from Remove old regulator. Plane-Power). Ensure regulator jumpers are set to match aircraft battery voltage (12V or 24V). Ensure that the R1224 jumpers are set for 28V. See Plane-Power R1224 Installation Drawing Ensure that the factory installed jumper between 12-1001.
Cut the terminals off the end of these wires and install new ring lugs provided with the R1224B Cut the terminals off the end of these wires and regulators. install new ring lugs provided with the R1224 regulator. Replace the regulators: Remove the Lamar regulators from the aircraft.
The R1224 has internal over voltage protection, so the Interav over voltage relay is no longer needed. Ensure that the R1224 jumpers are set for 14V. See Plane-Power R1224 Installation Drawing 12-1001. Add a jumper between SENSE and AUX on both R1224B regulators.
