Headlight works under acceleration only

Hello everyone,

I recently bought a 2009 250 rebel about a month ago. Unfortunately I laid it down and broke the headlight. It was a hard fall lol. I found a sealed H4 bulb at the auto parts store and was cheaper and didn't have to wait for shipping so took the bracket off of the original light and glued it to the new glass bulb. It worked fine for like two weeks. After not using the bike for a couple of weeks due to inclement weather, I live in Houston , the headlight stopped working unless I accelerate. Anyway I searched around the forums and came to the conclusion that it was the battery. I replaced the battery and still the same issue. I decided to keep the battery but now I want to be frugal with the spending as I almost just want to start throwing parts at it. My next guess is the rectifier but I'd like to get a second opinion or maybe a method as to how to test it or even which one should I get because there are a few on amazon and ebay and im overwhelmed right now. If I buy from ebay I risk getting a bad one as well I suppose. Thanks!

2 possibilities come to mind
1) a loose/bad/corroded connection stealing voltage

2) insufficient charging circuit voltage.


a) put a voltmeter on your battery while the bike is off, on but not running, idling, and when you give it come throttle.
b) disconnect the negative terminal from the battery and measure the voltage on the battery and on the wires while the bike is idling, and when you give it a bit of throttle.

c) use a voltmeter on the headlamp plug (BLU=highbeam, WHT=lowbeam, GRN=ground) while on but not running, idling, and while giving it some throttle.


let us know what you find and we will try to make good guesses as to where the problem is.

Ok I haven't been able to test the wires because the bike was getting reupholstered! I am trying to figure out how to upload the pics atm. But I wanted to add that the High Beam light stays on even though the switch is on low beam and the headlight does not work...

Well here is the reupholstered seat! They did some custom stitching also which I didn't really want, I would've gone for a diamond pattern if I knew they were doing that, but none the less very much an improvement over the old seats. The foam was replaced with high density so the profile is slim now. The rear seat was not even on there before because it was in baaaad shape

Alright, got some numbers in.

Battery reading

OFF: 13.2

ON:12.7 but the number kept going down for a bit until I started the bike, it seemed it would have kept going down if I had let it.

IDLE: 12.9

ACCEL:12-14

battery terminal with disconnected ground

OFF: 13.22

ON:13.21

IDLE:12.9

ACCEL: 12.9

headlight

ON: 12.38

IDLE: 13.10

ACCEL: 13-15

I forgot to mark low or high beam but the numbers where the same except the high beam seamed lower.

Also forgot to test the wires while the ground was off. I have no idea what to test or check. Thanks in advance

Update, the old bulb works perfectly fine, so I will be buying another original headlight assembly.

I don't understand why you need a new headlight asseembly.

Keepin' all the left over parts. Gonna use 'em to build another bike!

I have a 2009 so my headlight is not sealed originally. But since I broke it I bought a sealed bulb from autozone, I thought it was a good idea, inexpensive replacement. I took the bracket off the old assembly and glued it on the sealed bulb with JB Weld. It worked fine for a few days but after a few the light is just off to dim and only gets bright under acceleration. So tried the old bulb and it works perfectly fine. I want to get one of those LED headlights but I don't know if it would work or if any one has had any luck with them. Kind of like this one

If I had re-read the first post, my post above wouldn't have been needed. It's possible the sealed beam had too large a draw on the Rebel's feeble electrical system, causing it to dim.

The light you linked to says it will fit a Rebel. I'd contact the seller and ask if it's a direct fit/plug and play or not, and if not, what is involved in installing it. If you order it and can't get it to fit by following the seller's instructions, you'd have grounds for returning it.

Another couple of options would be to buy a good used headlight on ebay, or a new one from Jack's Rebel Warehouse, and install an H4 LED bulb in it. Both are plug and play, and cost less than you could purchase a new one in a dealership or online.
