Bizarre electrical gremlin

[chief1983]

To be honest guys, I'm not sure what I would be looking for in the TM to try to figure this one out. The 09 sat for a few weeks since I last had to move it, and when I went to take her out last night, the right turn signal indicator was half-lit as soon as I turn on the park/headlights. Activating the turn signal moves it back to an on/off cycle, but as soon as I turn off the turn signal it re-lights to half brightness. I just replaced the right rear brake light bulb and socket, and the rear and front turn signals all seem to be functioning properly in every state, yet this turn signal half-lights every time the headlights are on. Has anyone ever seen this? I just don't want to go replacing more lighting hardware unless I have a good idea of what the problem is. I'll probably start by removing individual bulbs though just to see if one of them makes the half-lighting stop. I'll pan over the wiring diagrams but again, I have no idea what I'm looking for to solve this one. Possibly a bad ground somewhere?

Start cleaning grounds and connections .

Yep, the head light is back feeding though the turn signal bulb, GROUNDS

Did the problem start before or after you replaced the bulb and socket?

Sounds to me like you have a marker light out. Same thing happened to me.

check the ground wire at the right side of the radiator support. along with all the other turn signal grounds.

I was having a similar problem and found it was a bad ground under the dash.

I had a similar issue also, was told to check grounds as above. When I pulled the front left parking light socket, my problem was w the left side, inside, the socket, the ground tab had broken off and unable to make contact. In my case, there was enough of the ground tab left to simply pull it up and make it work, problem fixed. I do believe the big box auto stores have replacement sockets for around $10.

It happened several rides after replacing the taillight socket, and all the markers appear to still be working. And the issue occurs with the parking light setting, where the headlights are off, and with the headlights on. But yeah, I'll check the mentioned grounds, and any more I can find.
