Im working on a cgafc air cooled chiller used for process cooling, my problem is the unit keeps shuting off on HI comm loss between modules, unit says check wiring, all looks good even the connections, i will add that the last time i had this happen i changed the (1u something number board,cant remember number) and all was well for a while,I changed that board due to corrosion,should have cahnged the others next to it as well(1u90 and 1u91) but trying to save money, anyways when i shut power off and reapply it, unit says HI comm loss check wiring between modules. I have several other units i have to work on so this one is on the back burner, any info is appreciated

the wires are not shielded so look for ANY wires that carry ANY voltage and move them far away.The weak aren't destroyed by the strong.
The weak are destroyed by the under-estimated.
