I installed a headlight modulator on the bike. It stopped blinking all the time, and only does it intermittently, and I haven't been able to really correlate the times when it is not flashing. Sometimes when I pull up behind a car at a traffic light, I can see the reflection of it blinking, other times it is clearly solid. Other times when I rev the engine it stops blinking, but at idle it is blinks. Even other times it is never working for days at a time.
I thought the headlight modulator was faulty, and it had a 12 month warranty and I was only 5 months into it, so I sent it back to be repaired. The company then checked it out and said it passed all tests and works fine. I talked to their manager on the phone and he said it has been their experience that many times when folks send back modulators and they turn out to be fine, that usually it is a problem with a faulty voltage regulator.
The guy further told me that to really diagnose a bad voltage regulator, you need to take it to a shop that has an oscilloscope. He said when regulators start going bad, they can cause pretty high voltage spikes that a multimeter or other diagnostic equipment won't catch, because those show the averages, not real-time metrics. Whereas the 'scope will show everything, even short spikes. OR at least thats what I recall him telling me. I am not an electrician, I have very little electrical experience to draw from so I was planning to take his advice and get it checked out.
Well I went to my Honda dealership and asked, they said they don't have an oscilloscope. Furthermore, the new regulator from the dealership was like $177 or something . I priced them on eBay and can get a used part for $45 shipped.
So my plan was to put in a different voltage regulator then re-install the headlight modulator and hopefully everything works out. I figure for only a $45 part I can see if it is indeed the regulator instead of spending almost that amount on diagnostic work. Plus I don't know of a shop with a 'scope and I really like to do my own repairs because I don't trust a lot of shops.
So that's the whole story. Not 100% sure the voltage regulator is going bad, but for $45 and some time in my garage I am willing to get my knuckles dirty and see if I can swap it out in hopes of getting the headlight modulator to work properly. I really feel like it helps in all my commuting traffic to help me be seen.
Any advice is much appreciated. Thanks guys.
