liliput input volyage problem
I ahve a 8" liliput touch screen monitir, i rigged it up in the car a few weeks ago using the ciggy connector and it worked fine. I have a power adaptor in my workshop that outputs the same volts and required current so i can test it satisfactorily on the bench. I have come to install the screen and all i did was cut off the ciggy connector and connect it to a 12v Acc feed and a good ground. No joy, i can not get the monitor working in the car at all.
i have checked the volts at the acc output and it is 12v engine off and peaks at 14 v when engine on. I checked the output at the connector and it is only showing 8v max. in the lead there is an eliptical box which i assume is a regulator. could this have broken in any way?
I cant understand why its only ouputting 8v
Regards
