hattymender Posted July 24, 2009 Share Posted July 24, 2009 Does anybody have a wiring diagram for heated screen on a 110? Mine wasn't working. After a lot of mucking about I sussed that the relay wasn't earthing and circumvented the existing wire with a direct earth, hey presto, a click, and 12v at the screen. The earth wire looks to be an involved set-up with diodes etc. in the line. Why? What do they do? And is it a bad idea to bypass them?
