Xinter thank you for posting the above. I will print it out and study it, then try the dimmer again to ensure i dont have 11dcv while the dimmer at its brightest. If I dont, i assume i am not getting proper voltage to the switch, therefore a problem upstream. One thing (of many) I dont understand, the radio lites are working. The dimmer has no effect on them. Any comments, tips, suggestions are more than welcome. Thank u.
