Hey all. Just got a new to me 2013 XT660X

Took it on my second ride and discovered a problem.

I noticed the indicator was flashing quicker than normal.
Then suddenly left front indicator stopped working. I figured it was a blown lightbulp, that can sometimes cause the indicators to flash quicker as well.

When I came home and got off the bike and turned on the engine I wanted to check the indicators again. Suddenly everything worked fine and the left front rear indicator was working too. I turned on the engine again and they still worked fine, no problem.

Any idea what could have caused this? Im not good with electrics.11
