Zongshen 200GY-2 H4 Headlamp Conversion

[jeepsteve92xj]

I think you may have the wrong lead to the common blade of the bulb.
Matching colors isnt necessarily straight forward.
Use a volt and ohms meter to figure out which is which. Seems I had a similare issue - when I first connected the wires the new H4 didnt light properly. I sorted out where the scooter wires lead, and connected them to my socket leads. I used male and female spades to do the connecting, though maybe I'll switch to soldered joints later.

I haven't had a single problem with my H4 headlight conversion; it works great! Do you own a Zong, Daha? :?:

Seconding what Jeepsteve said. Sounds like you just have your wires in the wrong order. I also did this the first time I wired up mine. IIRC the top pin* is ground which will be a green wire. the other 2 pins on each side of it are low and high beam.

I could never go back to a stock bulb. A 45w h4 works great on mine. Even without a regular battery (Kickstart with a little 12v 4a/hr battery to act as a buffer on the electrical system).



*"top" as in looking at it installed : '' : . The pin that is turned a different direction than the other two.

I missed JeepSteve's post because I didn't realize this thread had started another page. I concur. The H4 headlight conversion should work well for either a Zong, on a hondoid. If the high and low beams aren't working properly, you very likely wired the H4 connector incorrectly.

Yes, my Zong is a 2006 (I've got a couple pics of it on another topic... the CDI thread I think)

Well, it's an interesting problem. I installed the new H4 socket/assembly and matched up the wiring--green to green (which is ground), and then the other two. I've tried them both ways and each gives the same result. One beam is weak to almost non-existent, and the other is fine. So, no matter which of the two sets of wires is connected, both yield the same result--only the Lo & Hi beam selection is opposite of course.

I took the H4 assembly back out and put the old one back in (the BA20D socket & bulb). Works fine. Both Lo & Hi beams work as they should. So, I'm guessing it's either the H4 bulbs or the H4 socket. The bulbs are by Sylvania and they're 12.8v, not 12. Maybe that makes a difference? What is the voltage output of the H4 Eiko bulbs??? Are they 12 or 12.8?

With the H4 Sylvania XtraVision bulb in action the "one" beam I do get is great. It's many times brighter with a much wider field of vision than the standard BA20D. There's no comparison. But of course, if the bulb burns out at night while riding I'm screwed...the only option I have is to run my Baja lights (and one of those doesn't work either--that's yet another fix).

I'll keep messin' with it. It has to be something simple.

I doubt the problem is caused by either the H4 bulb or the H4 socket. I would guess something is wrong with your light switch, or you have a wiring problem somewhere else in the circuit. :roll: I encourage you to read the following thread.

Here, I was out doing some work on mine and snapped you a picture.



It's kinda washed out but the wire colors from left to right are GREEN - WHITE - BLUE. I was wrong above about where the green wire was supposed to be.

As I said, check out the following thread, Daha.

I bet you got the wiring wrong. Here's how the wires connect to the H4 bulb.



Here's how you need to wire the H4 socket.

To me it sounds like the ground (-) wire is connected to the 'hot' (positive) terminal of the High beam terminal, and the hot (+) wire to the common ground / negative terminal of the socket / bulb.

Swap those two around and you should have lights on both high and low.

That implies that you have 12+ volt inputs at both live and ground on the low beam, which would explain no low beam.

If I got my electrical theory from 30++ years ago right...

Yes, that was it Spud...wires were all bass-ackwards. I think I got it now. As always, excellent information Spud. Thanks for all the help guys.

[SpudRider]

You're welcome, Daha. The Zong has an superb headlight reflector. You should enjoy excellent illumination with the H4 bulb modification for your Zong.

Incidentally, the H4 bulbs are manufactured much more robustly than the BA20D bulbs. Therefore, the H4 bulbs last much longer than the BA20D bulbs, even when your are pounding down the trails.

@Dahamaster
Have you converted other bulbs to led? Can this H4 45w bulb conversion be done without changing other bulbs to led?

Yes, the Zong's stator is strong enough to support a standard, 55W/60 H4 bulb without converting any of the bulbs to LEDs. You don't need to limit yourself to a 45W/45 H4 bulb, and you don't need to change anything else on your Zong to conver to H4 lighting. I encourage you to convert your headlight to an H4 bulb; you will never regret the decision. The Zong has a excellent headlight reflector, and you will illuminate the highway superbly after you install an H4 bulb in your headlight!

Thank you Spud. I might do this conversion. I don't do much night riding but it's good to have strong light. I was thinking of 45W/45 H4 bulb as it's more on the safe side.
But if stator can support 55W/60 H4 bulb than i'll go with that. Your light is always on so you've tested it a lot.
