heated clothing / 12v power supply / fuse trips?

[Deleted account 220427002]

am going to try wiring the jacket + trousers direct to the battery - will let you know if this cures the problem....

it looks as if both the autocom and sat nav are wired off the rear of the 12v powers socket under lefthandside of seat - both power down after 15 / 20 seconds after turning the ignition off.

it occurs to me it wouldn't be a problem to "hard wire" the heated clothing to the battery cause i am obviously gonna leave the bike (and dissconnect the clothing) when i turn the ignition off so battery drain won't be a problem...

thanks for all your comments so far...

SEE.. don't say we didn't tell you (exits smug mode)

Hard wiring it should solve the jacket and trousers problem... but not if there is a software problem..as mouse has said... you may still lose the gps and Autocom power every now and then

SteveUK - just make sure you put a fuse in the direct-connect circuit. Else, if you HAVE got dodgy trousers then your gonads might get warmer than is good for them!

Desite what SteveUK thought in his initial post, it’s been obvious from day one that the GPS and Autocom could not have been hard wired into the battery or they would not have switched off when the combined jacket and trousers were added into the circuit, shutting it down.

In his first post SteveUK told us that he hadn’t been losing the power to the GPS / Autocom / heated grips, until he added the trousers to the jacket. So it’s tricky to see why, ‘you may still lose the gps and Autocom power every now and then’. Why, if he didn’t before, might he start losing them now?

There is no evidence provided to support the suggestion that BMW have somehow watered down the auxiliary socket as part of an updating of other software. This looks like one of those conspiracy theories (see recent ABS posts).

The most likely answers still lie in the dodgy strides / leads / connections and the equally plausible simple possibility that the combined trouser and jacket combo is drawing more than 10 amps when firing up from cold, tripping the system.

A quick check with BMW about the power capabilities aux-socket (why would they lie if it’s not really 10 amps?) and a call to the manufacturers of the heated clothing about the load it draws from cold should help to dispel (or confirm) two of the possibilities. If both possibilities are subsequently proved negative then it’s more than likely it’s dodgy wiring somewhere in the heated clothing.

Or SteveUK can just wire the whole kit and caboodle to the battery (don’t forget a suitable fuse) and we will never know.

I'm not suggesting they watered it down, more that they broke it

I don't think it's a "conspiracy theory" to suggest that a bike whos parts are mainly controlled by software may have a bug - how else do you explain what myself and another member are seeing, where since the recent software update, the accessory circuit turns on and off at very regular intervals, regardless of the load. A problem that did not occur at all before the update, with exactly the same accessories and wiring.

I agree however that it doesn't sound like this is Steve's problem, I merely mentioned it in case it was relevant.

Hi Mouse,

I agree that it appears odd that the aux. socket on your bike seems to be randomly switching on and off after a specific software update. Perhaps it’s coincidental, maybe not? With problems like yours (difficult to replicate and leaving no visible tell-tale evidence, unless something lurks within the diagnostic memory of the bike, which none of us can access easily) I have generally found it best to talk directly to the manufacturer rather than going through a dealer. If you have a real concern and do not seem to be getting anywhere perhaps you could address it to the bod at BMW customer services? He, very helpfully, advised what the Amperage of the auxiliary socket actually is (see numerous threads on this and other Beemer websites, with figures ranging from 5 to 20 Amps) – a useful start point if anyone wants to investigate mysterious switching off and resetting of the Can. He may well be able to help. BMW, like any other large manufacturer, are brand aware and will usually take a direct request for help seriously. Let us know what the Panzers say, or if you find out what the root cause is.

I can see that your advice is well intentioned. I was simply concerned that SteveUK might go off on a comparatively complex (Can and its attached bus) investigative route before exhausting the apparently more likely and cheaper answers: Shorting clothing / lead or a high Amperage draw from cold. Either way, he appears to be cutting out the ‘middleman’ and wiring direct to the battery. So we will probably never know.

hard wired to battery terminals in the end

thanks for all your comments / posts on this.

i ended up hard wiring to the battery terminals and all now works fine.

No fried gonads then?

Glad to hear you got it sorted.

adding fuel to the fire ( so to speake ) had the lastest software installed
yesterday whislt having 12000 mile service and now heated vest with arm chaps does not work. remove either chap and it then works fine, swoping chaps and it still works as long as there is only one connected.
( it all worked ok before the updates )

I've also been having the same problems with my 2610GPS running off of the accessory socket since the update. It works fine some times and not others. Of course when I went back to the dealer it worked OK! Not happy with their attitude though as they just say its my wiring connnection! Im now going to take your advice and ring BMW direct.
