Next, place the red lead on pin 1 and the black lead on pin 2. There should not be continuity through
the diode.
 If the diode passed the above test proceed to step #6.
 If the diode did not pass the above test replace the diode and then proceed to step #6.
N : Connector CM28 & wire 149 on the illustrations are for reference only; the specific connector
OTE
& wire numbers may vary. To find the diode on the wiring schematic, locate wire #130 and
trace it to the diode pack, typically on page 1.
Step #6) Reconnect the diode onto wires 130 and 149. Check for voltage on wire 149.
 If voltage is not present, then the diode continuity check was performed incorrectly. Replace the
diode.
 If voltage is present on wire 149 then proceed to step #7.
Step #7) Locate wire 149 at Node 10, connector X10, pin 16 AND spade location 1 of the pump
relay. Check for voltage.
 If voltage is present, then the node 10 is defective/damaged, replace it.
 If no voltage is present, then the 149 wire is broken between the diode location and Node 10.
Locate the break and repair.
