Hey All, So quick question for some of you HP 3 series owners. I had a 16.42.10 error yesterday. Bad curing module and had a smell of something burning for a sec. Decided to fix this one myself. Pretty straight forward. My question is, does anyone know how the modules are numbered. Is it right to left or left to right. 1234-4321? It hard to tell by looking at the module which one is bad. Also, is it wise to change resistor board as well as the Service Manual says the cause is a disconnected or bad resistor? Thanks for the help.
