Long time no see folks, but a weekend of maintenance attempts naturally drove me back to the forums in search of confidence...

I successfully changed my own front tire (yay me), however my goal of a full fork job was stymied by the lock tight situation on the front fender. Thanks to the forum for the sticky on that, I wish I had visited here before I got out the wrenches. I’ll be attacking it with drills and vice grips as needed once I get a free weekend.

Now, after a successful patriot ride this weekend, my headlights are dead this morning. Running lights are still working, but no headlamps or brights. I knew this was a relay issue on the older wees, but was hoping to get some common sense advice on troubleshooting this.

So to recap, dead headlamps, tiny running lights working fine, no other electrical issues that I can find...I’m a 2012 dL-650A with about 63k miles. Where do I look first (and if there’s a thread on this feel free to send me that way).

lack of relay is the issue. Type 'headlight problems' in the google search box and you will find the information to a common problem many report. Once you have the problem fixed installing a headlight relay can prevent a recurrence.

Check in right push start switch box first and foremost, expect to see burned out contacts. Main wire loom down by the radiator is also another, lots of great info here and even a sticky thread for this issue. :)

2 places to look. Take the start switch apart and make sure the contacts are not burned up. There are 4 contacts within the switch, 2 normally closed contacts for the headlight and 2 normally open contacts for the start relay. The headlight side of the switch is a normally closed set of contacts that open and remove power to the headlights when the start button is engaged. The headlight contacts will become oxidized, the resistance will increase and burn up the contacts. You can either install a relay to prevent this or you can disassemble the switch once in a while and clean the contacts. Be careful taking the switch apart. There are small parts in there. Take pictures and be careful. It's not hard just fiddly. I make cleaning the switch part of the valve clearance check. There is also a large white connector just aft of the radiator. You have to pull the gas tank to access it (I think, it's been a while). The headlight wiring goes through there and if the contacts become oxidized, they can overheat and burn up.

All: wanted to circle back and update on this...

The concept of taking apart the right side assembly to diagnose this issue was daunting, but honestly I was surprised to find that I was in there, contacts fully cleaned, reassembled, and moving in under a half hour.

Thanks for the moral support and technical guidance!

Awesome, now be sure to install some headlight relays from Eastern Beaver and never worry about it again. :)

what Big B says as other issues beside starter switch issues have been reported as well. I recall posts that mentioned burnt connectors in the circuit.
