It's one of the parts that I have found broken. There's no continuity in that one. Other identical 63 marked parts seem to be in continuity. Looks like a fuse to me but not sure and I don't want to break something. 63 for 6.3a ?
I've had such color problems with cps3 on older chassis on my nnc pb9929 and riverservice jamma harness, on newer chassis pb1843 the problem wasn't happening. Jammafier ruled out all the problems. Seem that cps3 have some color incompatibilites with some hardware when connected directly
