I use a CTEK MUS 4.3 to keep the battery of my 2013 981BS topped up. I have always used the power outlet and an adapter to deliver charge to the battery and until recently, it worked fine. However, the other day, after a week in the garage, I hooked up the charger, LEDS's lit successively as expected. Upon return the next morning, the main power light was blinking green and no other lights were on. This is what one will see if you plug the charger into the wall and leave it disconnected from the battery. So, I have tried all the tricks mentioned here....turning on the key for a bit, turning on the key while connecting and I have tried all three power outlets...same behavior. It suggests the power outlets are on initially but they time out after 15-20min or so.
Don't know why this would change or if there are any other thoughts about why this is happening. Its a new battery (the charger worked fine, even after the battery change, which was made about three months ago) with full charge and normal function. I have lost my direct to battery connectors, so purchased a couple. Will try connecting directly to battery and hopefully that should resolve the issue, but still wondering why my power outlets are all timing out now when they never did it before, nor do others have that experience!
