hi,
this is obviously an issue difficult to troubleshoot without being able to see/work on it directly.
I have an '02 f4i. I got it last year it came with a dual headlight mod. at the end of the season, the headlights suddenly died. what i mean by that is, when i turn key to on, no headlights come on and toggling between regular and high beam doesn't do anything. I decided to leave the problem till this season.
This season, I just took the bike in for service and asked them if they minded taking a look. They were kind enough to superficially probe some of the wires with a multi meter. The tech said that there was no current getting to the lights.
I thought it may have been a lose wire so i removed the front cowl to poke around and look. No visible physical signs of problems. I checked the fuses and they looked fine too. I even swapped the 10amp fuse with another one just to be sure.
If i take the bike in to a service center without knowing what the cause is I can already guess i'm gonna spend a lot of $$$ for the tech to even just troubleshoot it, let alone fix it.
Does anyone have any suggestions or ideas on what i can do to narrow down the problem, or even (hopefully) resolve it?
thanks in advance
