We took off the 851 4500C board and observed this burn. Is this caused by a problem with the same board or with something external? I do have a spare board but do not want to take chances. The voltage measured at some points in the board (ex. door switch imput) is 30V. I thought it should have been 24V. Any ideas as to which is the root cause of the burn on the board?
Thanks,
