Hi guys ive just run into a little problem with my link storm I have the aux 4 output wired up to give my electric power steering pump a signal to turn on and has been working perfectly fine but all of a sudden has lost signal out of the computer, flicked on the test mode and still nothing, is there something else im missing that would get this output working or would this mean I've exceed the current draw for this output? Thanks dylan
