87 k75 failure to start.

[mburnley01]

so i have been working on my bike i got it to start just fine but the little green button was broken so the button just dove in ans kept the starter turning. I fixed that part. But now when i turn the key, headlights come on, but no diagnostics. None of the cluster will self check. I tried arcing the tabs in hopes it will turn over. Nothing. The fuel pump is not running. The fuses are all fine. Im at a loss.

What was wrong with the button and how exactly did you fix it?

[mburnley01]

I drilled a whole in what was left mounted a spring and stuck a washer on what was left and epoxied everything together.

Sorry, the top of the button was broken off when I got it. The spring was also gone.

You can see that the assembly is more complex than a washer. I think you'll need to find a replacement switch or fabricate parts that you can see in the following posts.

Thanks! I'll take a look.

New switch assemblies are $140 plus shipping at EME. Somebody out in the Web might be fabricating only the parts you need, if only you can find them. Used ones will surface but you need to make a list of bike salvage outfits, visit their websites regularly and pounce when you find one.
