Yes, both the DCPs are set to 8 volt, 4 amps.
Slot 2 shows CC lamp on, slot 1 does not.
If I adjust the current, up or down, on slot 2 the CC led goes off, turn the channel on, CC led stays off, turn the channel off, the CC led lights up again. Adjust the current, up or down, and it goes out.
Slot 1 does not have any problem.
I hope this may give you a clue, if you need any more information or tests just let me know
