I have an 'o5 fxst i had the headlamp replaced to a H5006 assembly i am running what appears to be a white/black/and yellow 3 wire terminal system from the wires coming into the headlamp. the problem i am having is that with the low beam on it is as bright as running in front of the bike with a cigerette lighter. the high beam is ok but could use to be a little brighter. this all happened right after a rock hit the headlamp shattering the lense and causing both terminals to contact shorting out the bulb entirely. I do have one extra wire that is connected to the housing itself for ground but after trying to attach it with the other black wire and by itself with out the other black wire nothing changed. could this be a problem in the dimmer switch itself. i figured the low beam would eventually blow if it were a short and or not work at all. the high beam has never blown. but why would the low beam be so dim? and to be correct which wires are supposed to be whre the yellow i believe is at the top with the black on the right and white on the left?
