Short electrical shut-down during starter operation

[lieberty64]

My 04 1150 GS has a short electrical shut down if it didn't fire on the initial turn & you keep the starter going.
There is a very short cut in the action & the clock goes back to 0:00 as if the battery was disconnected.
It always done it since I had it (5 years), I doubled the battery leads suspecting a bad battery connection but it still does it.
I just seen another 1150 that does it so probably it's not a one off, is there any relay or other component that causing it & can be replaced.

Sounds to me like battery is not holding a full charge, how old is the battery if you have had this problem four five years on same battery?

It did it with the old one & this one is about a year old.

I have the same issue with my 2005 GSA, it was cured by a new battery 3 years ago and now same problem, I am putting that down to a failing battery.

You are the 2nd one to say so, probably right.

It's maybe the starter taking to much current, either way it's because the battery can't cope with the starter draw!

What battery do you use?

Three possibilities come to mind:

--The battery is not getting fully charged when you ride. After you leave the bike overnight, what is the voltage?

--The starter motor draw is high. This can happen if a magnet breaks loose or if the planetary gear cover, inside the motor, comes off and falls into the armature (happens on some starters).

--Your battery is defective. Get it load-tested to check.

I've had this and it was the planetary gear cover on the starter motor.

Thanks, it's the BMW jell, about a year old, never checked voltage in the morning, will give it a load test.
If it is the planetary gear cover (not sure what it is) how long would the starter survive with bits floating in it.

It's a flat round disk inside the motor which is a cover for the gears. It can sit there a long time and the starter will still function but with intermittent problems.
