as per the email on the 8140...facia lights dont work
you told me to study pages 11 and 12 until i did understand , i simply dont , i have no electrical training or experiance , im just a broke guy trying to make a old unit work
Page 12 shows you the back of the display board and shows you where pins 1 and 2 are. Continue counting across the terminal block. That will tell you where 3 and 4 are. All even numbered contacts are on the top. All odd numbered are on the bottom.
