I installed LEDs in both ST’s (and the scooter) some time ago- the 2000 has been fine but on the 94, I noticed the high beams on both sides didn’t work, and if I switched to high beams, I had no headlights at all. This has been going on for some time, maybe the past 6 months if not longer- sometimes they’ll come on and a minute or 2 later, they’re out again as well as the indicator light on the dash. So, I got accustomed to just ride with the low beams and installed a couple of cheap bullet lights (for some extra visibility to other drivers):
Still, as many here would do, I had a decent weather day in the garage (with the AC on) and wanted to seek out why they weren’t working- I checked the switch (I have a spare and tore into the bike to connect it (but not on the handlebar) and same thing happened (no High beams). I then checked the 3 relays (2 for the headlight and one I assume for main engine start- sounds like a rocket launch). They checked out fine, but still, no highbeam. Also checked voltage to the light via the harness when the highbeam switch was on- no dice. The last thing I checked was the fuse (likely should have checked it first)- fuse was not broken/blown, but I did put some dielectric in there when I had an issue with the fan not coming on due to corrosion on the fuse some time ago (put the grease on all the fuse contacts, maybe too much so)- today, I sprayed some QD contact cleaner at those 2 fuses (high first) and cleaned all grease off the fuse- SUCCESS!!!!. Then I cleaned the low beam. Now I have high and lows working as they should. So I asked myself ‘Self, is it possible to use too much grease on a low current draw item??’ I guess the answer is possibly…
I then looked up a YT video to see if anyone else had this issue, and here’s what I found:
I just don’t know, maybe it’s a happy accident that it works again- we’ll have to wait and see. What I also did (really didn’t want to) is pull all the ABS/TCS fuses as well as the dash bulbs for ABS/TCS- it has been a problematic system earlier after I bought the bike back in 2014- not sure why, but right after starting, I get the flashing ABS light- hitting the warning light disable has stopped it in the past, but the left side of the ABS light stays illuminated and at times, it looks like Christmas lights up there with TCS off, ABS flashing and TCS flashing as well- I can’t seem to pin it down and parts are unavailable whatever the cause (I have done diagnostics via the service manual and I have had a #2 fault, then a #3 fault, then others as well, so I don’t know if the whole ECU is shot or not- while I) own it, it’ll remain a non ABS bike I guess but it brakes normally, and I’m mostly a fair weather rider anyway.
I will plan to swap out the steering head bearings next- likely next week depending on how hot it is in the garage.
