Outputs have 10v when all off
Hello, first time using a PDM15 v2 so im wondering if i have made an error myself in the programming, Im trying to test my ecu on and off but everytime i turn off the output the ecu is staying on because the output reads 10.5-10.8v, same goes for all the other outputs those devices just dont turn on, they all read 10.5-10.8v, ive tested all the outputs in case of any back feed and there is no power going back other than the Pin 3 on the green DT connector that requires power. Thanks for your help!

Unless you have a pulldown resistor attached to the output, or an actual load, then you will see this. We have an installation where one of the outputs drives a fuel transfer pump. The output line is also connected to an engine monitor input to display an alert when the pump is on. If the pump is not connected, the monitor thinks the pump is on because the output floats high. But when the pump is connected, everything functions as expected.
