I'm curious about the comments about the clusters being the same from those who have "looked" at them... Are we talking a visual inspection and comparison or has anyone measured the ohms on the resistors to see if they're good or not.
I haven't had my cluster out, but it looks a lot simpler and less complex than I'd imagined. Seems like it'd be easy to test it and replace the offending resistor(s)...
Has anyone tried ohm'ing them out?
