Just wanted to say how helpful this thread has been. Thank you so much HOTNANAS. I like your attitude too. Even though you've posted answers already, you're not telling people to STFF and instead you've just simply reposted. I would really encourage others to read through the thread before asking questions though b/c repeat posts are making this thread way long. Hotnanas spent a lot of time helping us out and the least we can do is read through the pages.
Thought I'd post up status of my project. I don't post here much but hopefully this can help someone. This is an old thread, so there's been some new products released since its inception.
I bought the DDM Tuning low beam kit ($25) with H4 bulb for my Vino 125 and the $15 relay harness. I had called DDM Tuning and was told the harness that comes with the high/low kit is not the same as the one sold separately for $15 with the relay. I figured if I get the low beam only kit, I can use the highbeam switch on my scoot as an off switch for the HID's if lighting it up is successful. From reading, it sounds like it's better if the headlights are NOT turned on with the ignition, but afterwards. The Walgreens 9v battery is just there to show the scale of the ballast. It's uber tiny!
Received the kit yesterday.
Plugged it in over the evening and the headlight flickers.
The relay also vibrates violently going on/off a billion times a second. Kinda freaky.
After researching a bunch on other forums (mostly car ones) where people had the same problem, they've also opted to install a capacitor which helped a majority of the folks.
So where I'm at now is I need to go buy a capacitor after work today and give it a test.
My project status is all outlined in my blog (see sig) for anyone who wants photos (yet to be uploaded at the time of this post) and other detailed information beyond the scope of this thread. I found a way to install the capacitor w/o soldering. So for anyone who's freaked about about electrical installations like that may want to point their browser to my blog for a quick video showing how the capacitor can be installed. (Not my video. Just found it online from another forum).DIDN'T WORK:
Still flickers even with the capacitor. Is it possible that I'm actually supposed to connect the negative wire to ground instead of the negative pole of the battery? Sorry if that's a dumb question. I'm totally stupid when it comes to electronics. I can swap out my suspension, redo my brakes on my car, but for the life of me I don't know anything about anything involving wires.CAPACITOR POPPED:
I tried it again but this time grounding the negative wire instead of putting it on the negative pole of the battery. I don't think it's because of this move that made the capacitor pop. Probably just a coincidence. Does the blown up capacitor mean that the capacitor was not big enough or perhaps that I installed it with the incorrect polarity? This was my third try of the day and the capacitor probably just about had it. I've seen someone use a 470 microfarad 35w capacitor instead of the 100 microfarad one. I'll go pick one of those up tomorrow to see if that works unless someone recommends otherwise. I remember one of you tried that and it still didn't work. You ended up hooking up a switch to the system and now everything is fine and dandy.
Not thinking that'll work for me b/c my setup already acts as a switch. I turn my scooter on with the highbeam setting which is my OFF setting. After idling for a bit, I turn it to low beam which turns the scooter low beam on (or least that's the goal). Still flickers. I'm definitely open to other suggestions. Let me know what advice y'all have. Thanks.NEW CAPACITOR:
Does anyone know why capacitors blow up? Not certain whether it's b/c:
A: Too much current is going through the capacitor and it just can't handle it
B: Incorrect polarity (AKA, I hooked it up incorrectly)
C: All of the above
D: None of the above.
E: Either or.
