Replaced the RFCM, arc/IR card and PMT arc det. and still failing to test the arc detector. Arc interface isn't firing test but I've looked over the backplane inside / out and tightened all cables after checking. Went downstairs and checked out connector at the PMT arc det and didn't see any pin wire problems. Worked Monday with RFCM replacement until the next day and stopped testing again. Might try looking at RF crate and another RFCM after I checked the analog/digital connectors on it and reseated with same failure.
