K75S Tries To Start On Its Own

This is somewhat strange so I thought I'd see if anyone has any ideas.

The battery on my K75S was down so I decided to put it on a charger. I hooked it up and pluggged it in. Right away the charger started humming louder than normal and all of a sudden, the engine slowly turned over once. I quickly pulled the plug and noticed the charger was set on the highest level (50 AMP START).

So, I set it correctly and plugged it back in...it did the same thing.

I then pulled the negative lead off of the batter to let it charge. It was fine and the charger made the normal hum.

A few hours later, I took the charger off, and touched the negative lead to the negative post and the bike immediately tried to turn over.

There are no lights on the instrument panel and the key is off.

Any ideas??

k75s tries to start

hello,
been there, done that, check your starter relay, make sure your battery is healthy,(state of charge, electrolyte reading, etc). - victor

Update!

It was the Starter Relay. I removed it, lightly tapped on it with a small wrench, and the rest is history.

Thanks for the info everyone.

I had this problem with my '92 K75s a few weeks ago.

What's going on is that the low voltage coming from the dead battery causes higher amperage to flow through the relay, which means higher temp, which fuses the contact points so that the engine keeps trying to turn over. Once you get the battery disconnected and pull the relay, you can break the contacts apart, but by then the damage is already done. If you take a look at the relay you will see that the contact points have melted a bit. That means that if you keep using it, you don't have a uniform surface for conducting electricity. The relay will be more prone to fusing again if used in this condition, etc.

$70 bucks for a new relay was my solution, and I won't fail to take better care of my battery now.
