Headlight out want to bypass EHC

My EHC isn't powering up my headlight everything else works. Is there a safe way of bypassing the EHC and wiring in the headlight. I played with it a little and found the hot wire from the ignition switch leading into the EHC and was thinking of running a jumper wire from the hot lead to the low beam. Do you think this would cause any problems. Thanks, Jab

I wish I had more money.
Moespeeds did this. I think there is a thread about it here somewhere. Or shoot him a PM. You didn't buy the HID for your bike did you?

I just replaced my EHC. My problems began with the turn signals and then the headlight. Then after about a week or two of this I lost all power. Be prepared.

Keep it simple. Goto Home Depot and buy 6 feet of 18ga black speaker wire (2pair). Run it up to the headlight bucket and cut the lowbeam wire up by the neck and splice it in. Hook the other wire to the ground. Run the hot side through a 12v switch and make a little bracket to go under your seat to mount it on. Put a 10a fuse on the hot side up near the battery. Ground wire goes to ground on the frame or the battery itself and you're done. If you really need a high beam just mount another switch down there in the same manner. Once you start losing functions though you are pretty much screwed. I ended up bypassing my ignition in the same way when it went shortly after.

I'm telling you, the HID ballast picks up on these bad headlight outputs out of the EHC. The ballast shuts down into protection mode because of a lack of power on the headlight circuit.

It isn't the HID causing it, it is just the Ballast shutting down and then the EHC locks in a loop because the ballast is shut down.

There have been over 20 headlight circuits go out on guys bikes WITHOUT Hid kits just in the last couple/few months that have posted it.

That is why 98% of the guys I have sold Kits to have not had a problem, but the other few have bad, but not failed EHC's. The headlight circuit is the first to go in most cases, like Moespeed stated.

Thanks for the input guys. I guess when I can scrape up the money I will do the wire plus thing and be done with the thunder heart EHC's. No I don't have the HID headlight. I will do the wire and the switch but it sounds like only a matter of time before the rest of the EHC goes bad. Thanks again, Jab

I seem to think that there is a bad ground supply within the EHC to the Headlight circuit and after a few years it begins to fail. I think that is why on some bikes the EHC gets noise interferance from the HID ballast and some don't.

Either way, the headlight circuit has a steady draw on it all the time and has a long power/ground run to the headlight. stands to rest why it is first to fail.
