ADVANCED TROUBLESHOOTING
The AUTO-NET 440 requires a minimum current draw of 2 Amps on the LOAD pins in
order for it to switch off the other circuits. To verify the Auto-Net 440 is functioning
correctly, two #1156 lamps can be parallel to simulate the required current draw.
The following conditions will occur when the lamp is connected between vehicle ground
and each LOAD pin:
LOAD connected to LOAD A - lamp will not light no voltage present on LOAD B or LOAD
C.
LOAD connected to LOAD B - lamp will not light, no voltage present on LOAD C, voltage
will still be present on LOAD A.
LOAD connected to LOAD C - lamp will not light, no voltage present on LOAD B, voltage
will still be present on LOAD A.
Note
IF ANY OF THESE OPERATIONS DO NOT FUNCTION, REPLACE THE MODULE.
