F4I Headlights
 

Hi.

A couple weeks ago i put new Xentec HID lights on my 2001 Honda CBR 600 F4i.
last night i was going to go for a ride and found out that the headlights were not working. i turned the bike off and on several times just to see if it would make it work but it didn't. i also tried turning the high beam on and it didn't turn on (not even the high beam signal on the screen). today i tried checking the headlights fuse (Under the seat) and it was burned. i bought the same 10A fuse and a 15A fuse to see if either one of those would make the lights work, but as soon as i would turn the key on i would hear the fuse burn. I checked for any cables out of place or burned and couldn't find anything wrong. Could somebody please let me know what i should be doing?

Thank you.

You may need an adapter of some sort. I got a 250r for my first bike, and I ordered some HIDs off of Motorcycle-superstore. They advertised them as a plug and play item. So I hooked them up and they worked for about 20 minutes and then they blew a fuse, and I put another one in and it blew that, and another one etc. After doing research I found out that I had to buy an adapter or something for it that exceeded the cost of the bulbs that were already kinda pricey. So I just went stock. You should try to find out if you need an adapter or not.

You just need to go over the wiring more thoroughly. Clearly something is burning out, so take the time to diagnose it properly. Might require taking some fairings off and whatnot, but it's worth it given your safety.

I had a similar problem where my headlights were burning out as well, and for me it was the rectifier that was shot. The rectifier is on the left side of your back tail, you cant really see it unless you take the tail off. It's attached with two bolts to the side of the subframe. For me the whole back end was blown out, looked like a bullet went through but everything else on the bike was running fine, except the headlights.

If you have access to a multimeter touch the probes to the battery while the bike is running, and see what the readout is. While idling it should not be any more than like 14 volts. I know for me as soon as I revved it passed 3k it would jump to like 20+ volts and start frying headlights.

You also really should run the hids on a relay circuit so you dont mess up your stock wiring.

Thank you Mr. Suave.
But the HID lights came with two adapters. so i am not sure that could be the problem.

Thank you Aken. I might need to take the bike to a mechanic so they can look through the wires since i am not sure what i would be doing or how to fix a burned wire. I will let you know if that was the problem.

Thanks.

Aleksander. i will check this out and see if maybe that rectifier could be the problem.

Thank you.

My problem was the same and it was ONE, just ONE loose wire in the throttle side box. There's 3 screws holding that unit together. I sotered it and now they work fine. Could be that. Its an easy find on your own time

Correct spelling, FYI :icon_dopey:

haha. if you understood him than it is correct enough. :D
