Power window cable snapped on my 86 Spider Veloce. I've installed new cable on winder drum but the diagram in IAP shop manual doesn't seem to match my setup. I found two upper guide pulleys and two lower. Could use correct cable routing diagram. Also, I measured old cable and installed a new cable but there appears to be too much slack. What's the procedure for taking up the slack? Thanks to anybody who responds.
Thanks. I saw the sticky thread late last night but didn't read all the way through and missed the link to the schematic. I'll look at it more closely.

Update - I believe I figured out the proper routing for the cable although the diagram in the Alfa shop manual under the power window heading is identical to the diagram shown next under the manual window regulator and has more pulleys than my 86 power window regulator setup. I measured the old OEM cable and cut my new cable to that length but installing the new cable with nothing spooled on the windlass drum results in way too much slack in the cable. Without detailed instructions I reasoned that there must be a prescribed number of prewindings on the spool so that when the cable is routed properly it has the proper tension. What I don't know is how many windings to make and whether those all should be one end or the other or some combination. It seems that the ideal end state would be that neither the upper or lower end of the cable on the drum should ever come to the very end, else over time metal fatigue would result in bending the cable ends where they pass through the holes in the spool causing them to eventually break like mine did when I got into this mess. Does anyone know how many prewinds to make on the spool so as to end up with the proper installation of the regulator cable?

I dunno about # of prewinds, (prolly the same as a manual window if anyone who's got one apart desires to check), but your thoughts as quoted above are absolutely correct.
