Again...Low Voltage warning

[Wilko]

Have I just replaced the battery for nothing, last night when I went to do the gear linkage, I started the bike to move it, when the ignition was on, the dreaded low voltage warning showed, I have it on a solar trickle charge, that is working fine.

The new battery was fitted a couple of weeks ago, and has charged on the bike, I've done a couple of hundred miles since then, the charging system is also fine.
Could it be just throwing up a stored fault warning, how can I check and delete them, I don't have the datatool cable.

Search DTC codes. Coconut does a great explanation how to read the codes

The 'Low voltage warning' is such a common occurrence for many owners,......I'm convinced that it's a software problem rather than the actual battery.

Mine shows the low voltage warning every time it's started for just a second.  I think it's the heavy load of the starter motor that makes the system think that the battery lacks a full charge.  It doesn't show up with the ignition "ON", only after the starter motor runs.  I quit worrying about it.

The "LOW VOLTAGE" Warning Message isn't a Stored Fault Message.

It is not unusual for it to appear - as Trophied says,
while actually cranking the engine over with the Starter Motor,
when there is a heavy drain on the battery, and an inevitable Voltage drop.

If the message appears with the Engine Running, then I would look again at the Charging system,
and measure the voltage at the Battery - which should be around 13.2 Volts.

There's allways the possibility too, that although it is virtually Brand New, the battery IS faulty,
so get it properly tested while it is still under warranty 

Cheers

Cheers boys. The warning is displayed when the ignition is turned on, not when the bike is started.
I will get it checked out though.

Accepting the fact that at some stage, probably sooner than later, as my TT is 5 years young, that I will have to replace the battery.  Getting the low voltage warning for all of my ownership period - 4 years.  Like others I no longer consider it a dud battery.

I too have the low voltage while starting. On the BMW I previously had, the Xenon wouldn't start before I had the engine running out of safety. Perhaps it's as a precaution so the bike has power to crank the engine.
