I've now done 2500 miles in the 1250 GS I bought in March, and have experienced a couple of minor issues which I wondered if anyone else can shed any light on. The first is that the accessory socket is not shutting down after the usual delay, or at least not if a reasonable amount of power is being drawn from it at the time the ignition is switched off. The second problem is that I seem to have completely lost the average mpg readout. This is now blank, but I have definitely seen a figure on it previously. More details of these below if anyone wants to read it. I would appreciate any suggestions.
Thanks,
Fred
Power socket issue: I use a phone as a satnav, and need a high power fast charger 12V adapter to keep this from running out of charge. I was initially connecting this to the now redundant GPS power socket using a mating plug from Nippy Normans and a cable soldered directly to the charger, but experienced some issues with it intermittently switching off, which I put down to it maybe exceeding to current limits on this connection.
When I got a new 12V to USB adapter which has two high power outputs, one to suit my satnav phone and the other which is compatible with my new main phone, I decided to try powering it from the accessory socket instead, and fitted a full size 12V socket to mount it in. This new socket was wired to a right angle plug going into the accessory socket. This was all working fine, apart from not switching off when I turned off the ignition. If the phone is still connected and charging when the ignition is switched off, then the accessory socket never shuts off as it should after the normal short delay, and subsequently appears to stay on permanently. Even if I then unplug the charger it will turn back on if reinserted. However, if I unplug the phone from the charger before turning off the ignition, then it does shut down correctly, so it seems to fail to shutdown when a larger current is being drawn. This is the opposite of what I would expect, as the larger the current being taken, then the more important it should be for the system to turn the socket off to stop the battery being flattened.
I even tried putting a diode in series with the supply to the charger to prevent any possibility of a back voltage from the charger keeping the socket live, but it didn't help. Seems wrong to me, so if anyone has any further info on this I would be interested to hear. In the meantime I decided to try again with the GPS power supply socket as I had found that the intermittent failure when connected to that previously had been due to a faulty 12V USB adapter. I have now connected the full size 12V socket to this supply instead of plugging it into the accessory socket, and the new USB charger works perfectly in this. The USB charger turns off properly regardless of if the phone is connected, and can supply enough current to provide a fast charge output simultaneously to both phones.
If you have a need to provide both a Fast Charge 3.0 USB type output as well as a USB-C PD type fast charge then I can recommend this charger:

Here it is fitted in my new socket:
MPG readout: The other baffling problem is that the average mpg readouts on the TFT are now both blank. I am sure that this was giving me a figure previously as I remember comparing it to that from the spreadsheet I use to save details of all my fill ups. With my 1200 GS over the 11,500 miles I did on it, the bike gave an average speed readout of 47 mph and coincidentally an average fuel consumption of 47 mpg which agreed pretty well with my figures.
When I had looked at the 1250 figures previously, the average mph was 49 and I'm pretty sure that mpg was 47 - so much for the 1250 being more economical. Now when I look at the mpg readouts they are blank. I found something about fuel range readout not showing when the bike is on the sidestand, but that's not the case here, and shouldn't affect the average figures anyway, as they must be based on records of the total amount of fuel the fuel injection has supplied to the engine.
I did have the TFT software updated at the 600 mile service because it wouldn't stay paired to my phone, but I'm pretty certain I have looked at the average mpg readout well after that. The only other thing I have done which could conceivably have affected this was to change to km/h while in Spain recently. The other thing I have noticed is that changing the item displayed at the top of the screen using the menu button has now become very unreliable unless I wait a couple of seconds after each change. I am sure I used to be able to whizz through these as fast as I could press the button. Any thoughts?
Thanks,
Fred
