K1 starting/blinker/light issues
« on: October 04, 2016, 01:04:29 AM »
Hey guys I've got an intermittent problem with my new-to-me K1 that I brought back from Germany this summer.

Symptoms:

Occasionally when I go to start the bike I hit the start button and I get a single audible "click" but no turnover of the engine.  When this happens, my blinkers, headlight, and horn do not work.  Sometimes if I move the bike around then it will suddenly work again and start up.  When it starts up I have the following issues:

Headlight will not illuminate unless I rev the engine about 3000 rpms.  Blinkers will either 1) not work 2) flash once or 3) both blinkers will flash simultaneously once.

Once I ride the bike around for a minute or two all symptoms go away and everything works fine.  But if I turn off the bike, there is about a 20% chance all the symptoms will come back.

The bike has a brand new battery and it did this with the old battery as well.  Most of the time it starts up fine and runs with no issues.  I would guess it's a starter issue except for all of the associated electrical issues with the lights/blinkers/horn.

Thoughts?  Thanks for the help.

PS--I just moved back to the America and already did a round trip from Seattle to Montana and back with my RS and had a blast! Time for an oil change and new tires.

There is a connection between incipient starter failure and other electrical equipment malfunction. Here's a post for you that could be informative. There are also many posts on MOTOBRICK.COM that would be useful, too.

Shoot, then it could be the starter. Maybe that's why it suddenly works after I move the bike around, I'm getting carbon off the brushes.  Does that explain why I get light and blinker functionality only after the engine has been revved?

And when I put the battery in last week I told me wife, "See that there?  That's the starter, I want to clean that at some point."  And I should have just done it then.   Whoops.
