4.9. Removal And Replacement Of Pump Primer And Air Bleed Components
The following subparagraphs provide removal and installation instruction for select SAM pump
primer and air bleed components.
4.9.1
Priming Feature Valve Diodes
The SAM system utilizes two blocking diodes (Figure 74) to prevent unwanted interaction be-
tween the automated (SAM) and the manual (pump panel) primer signaling. Both diodes plug
into the green harness (each via a keyed two pin Deutsch connector); with one diode located be-
tween the Hale PRIME pushbutton and the AFS Sensor Module output driving the ESP priming
pump; and the other diode, located between the Hale PRIME pushbutton and the MIV–A Module
(and if equipped – MIV–A Module 2) output(s) driving the 4-way valves routing priming suction to
each MIV. See Figure 15 (page 18).
Figure 74. PF Valve Diode
The diodes install in the MIV-Auto Module Electric Harness. The diodes connect according to Ta-
ble 56. See Diode Troubleshooting (paragraph 4.16.2.8, page 169) to test a diode.
