Fault code: 24052 electrical system under voltage
« on: March 24, 2017, 04:40:13 AM »
Hello,

I keep finding this error every time i check the errors with GS911.
The error seems to be registered right after cranking the engine. Right when i press the starting button - on the display is shown the yellow triangle with the "battery" sign on the dash and after engine starts (1-2 seconds) both signs are off.
The battery is in good condition (MotoBatt MBTX12U (12V 14 Amp) 200CCA) - 12.8V when engine off, charging seems to be ok:14.1-14.2, there are no loose connections on battery side or starter side. I haven't check the connections on alternator side.
The bike always starts ok, no other strange behavior on this side.
I guess the error is logged because right in that moment when the start button is pressed - the voltage is decreasing under some "ZFE acceptable" level.
Is anyone else facing same issue?

Thank you,
paul

Not sure what bike this is but the head light usually turns off when cranking to reduce load, have you hooked up any thing that is on when starting the bike? Cleaning and tightening all connections is always a good idea but you might want to take the battery in to a "specialist" and have a load test done on the battery.

Hi Jim.
It is a GS 2008 with no additional electronics installed.
I have replace today the battery to a jmt lithium ion ...same behaviour.
:D
I have to get used to it or to spent hour investigating where is the high load when the starter is cranking.

Thank you,
Paul

Try holding in clutch lever when starting. I'm told it helps with not pulling down the battery and decrease's the load.

I have checked today the starter - everything ok - so no issue because of this.
... and still triangle and batter sign is shown each time i am starting the bike for 1sec.

I have the same problem with my 2009 R1200GS. I bought it used 3 years ago at around 50000 Km, now it haves 80000 Km and I always had that problem. A new battery last year did not change anything.

I think it could be the starter cables going bad... If you look at the electric circuit on the R1200GS, you'll see that all the electronic is not connected directly at the battery but at the starter post. If the cable is corroded, it will have more resistance and cause a voltage drop between the battery and the starter, thus causing a low battery warning.

I will try to upgrade my cables this week. I will fabricate new cables with a bigger gauge wire made of more strands (higher quality cable) to see if the problem goes away.

Hello friends...

I have the same issue in my 2012 R1200GS... I tryed to test the electric system with a special tool (electronic battery tester)... the battery is ok but when I press the start button, the voltage drops to 9V, so the tester say that it is a problem with starter motor...

I think that the starter motor needs lubrication in some bushings... The engine always crank, the motorcyle is ok... So, keep going...
