Corey,

The ADON board is below the LCECPU.
This may be your trouble. ADON 1 board is problematic, especially if faulting on 82 & 15. You might have to upgrade to ADON 2.
One difference between 1&2 boards is the location of X6&5 connectors. The 1 board has the plug locations at the bottom of the board. The newer board has the two connectors at the upper center, and a series of LEDs in roughly two columns under X5&6 connections.
Hopefully your book show the replacement procedure.
Relays K443:1 & 2 are top left on the ADON bd., they are soldered on.
