I am repairing the system monitor on my 1989 390 EC.
The main board is corroded but the components are accessible (not potted).
I think I can replace a few resistors that rusted off and a few wires over the corroded traces.
The remote termination board has a burned out resistor which appears (from numerous comments on other boards) to be a common failure point. Does anyone know what the size of the resistor I circled in the picture below?
