Quad Lock Wireless Charging Head - Battery Drain

[GrumpySimes]

I have a Quad Lock USB wireless charging head connected to my r1250gs via a nippy normans usb socket (replacing the old DIN socket)
Sometimes it switches off when I turn the ignition off but other times it stays on. I understood that the canbus shuts down the sockets when the ignitions off after a period of time, but this doesn't seem to be happening. A quick search here suggests that the canbus leaves the socket powered if it's pulling power when the ignition is switched off.
Anyone have the same setup with similar issues or solutions?

I have the waterproof one wired into the canbus and never had that issue.

USB is always powered on. Even when nothing is attached.

It either needs to be on a circuit after the ignition switch, or using one of Quadlock's auto switchy things which you can connect straight from the battery.

Flattened my battery. I unplug it now.

Use a Healtech Thunderbox power distributor (or similar) that is wired direct to the battery but also has a “trigger” lead wired to an ignition live source. I’ve used them for years, they are a piece of pi** to install and work infallibly. They also do not interfere with the bikes canbus system.

I think what the op is saying the unit is wired into the can bus, so once the ignition goes off, after so long cuts off the power but his doesn’t.

Hence why an isolated (from the canbus) distributor works.

Exactly that, it’s wired via the canbus. (USB via the BMW connector previously wired to the original din hella outlet)

Similar quad lock set up, NN Fast charge double socket. No problems with it not switching off after a few seconds and, no battery drain here.

It’s a new setup for me and it’s definitely been switching off sometimes, but I’m now questioning how often as when I left work this afternoon it was still on (parked from the morning) and I checked again an hour after arriving home this evening and again still on.

It don't sound right, does the blue light stay on?

Mine's a 2023 GSA, so it had the OEM USB before I swapped it for the fast charger socket. But I had the setup on my 2020 GS with a NN twin USB replacing the Hella.

Can you try to plug something else into the USB to see if that does it? at least it'll eliminate the Quadlock wireless charge head or lead at fault. or not.

I have a Chigee connected to CANBUS, drawing power all the time, this turns off after 30secs or so after ignition off.

The blue light stays on. I'll try disconnecting the quad lock and check to see if the USB shuts down.

There's an interesting thread on ADV rider suggesting a low current draw can cause the port to stay open.

I’ve run a few tests and on my 2020 bike, using power from the original hella plug connector, via NN usb and the behaviour is as follows:
Quad lock head with phone charging - power is cut shortly after the ignition is turned off and the bike shuts down.
Quad lock head no phone - power remains on indefinitely when ignition is turned off and the bike shuts down (if a phone is connected later & the ignition is still off - the power is then cut, unplugging the quad lock after the bike has shutdown doesn’t shut down the usb socket)

I thought they were both ignition switched but you learn something new everyday. What it does mean is that if I ride anywhere without the phone on the charging head, or if I remove the phone with the ignition off before the bike has shut the outlet down, the quad lock head will remain on permanently. Which probably isn’t ideal…

From quad locks site “If the power button on the wireless head is switched on, it will draw 12mA. If the power button on the wireless head is switched off, it will draw 6mA”
I’m not clear what else is being kept awake on the bike if the connector is live.

@GSian - any chance you can check if yours behaves the same? I wonder whether the nav connector and USB (previously Hella din) perform differently.

 

[GSian]

Strange, I'm getting exactly the opposite.

If take the phone off then turn the bike off it shuts down after exactly 60 seconds. even if I see the green light turn to blue.

If I leave the phone on and switch the bike off with the phone still on the charger with the green light on, and then take it off within the 60 second from turning the bike off, the light turns blue and it shuts down 60 seconds from removing the phone.

If I leave the phone in place with the green light on for longer than 60 seconds, then when I take the phone off, the light turns blue but never shuts down.

If I don't ever connect the phone, the blue light on the charge head comes on but then goes off 60 seconds after ignition off, as expected.

The Chigee device is wired into the Sat Nav feed and it follows the same pattern as the charger does.

If the charger and nav has stayed on, all I need to do is turn the ignition on and off, without connecting the phone, then it sits down as expected. It must re set it.




Hope all this makes sense and helps to work it out.

 

[GSian]

I'm assuming that if the phone was fully charged when I turned the bike off, the blue light would be on and it would shut down even if I left the phone in place. I'll try that tomorrow when my phone charges when i'm out on the bike.

 

[GrumpySimes]

Thanks for the info, agreed you have the opposite of what I’m experiencing.
Maybe it’s a bike age thing? Next I’ll try unplugging the quad lock head and check the nn socket with a usb cable.

This is why I waited for the hard wired waterproof one to come out, wired to a switched 12v supply, can’t be doing with usb chargers.

 

[GSian]

From what I can remember this was the same as my 2020 GS was, I transferred the kit over when I got this GSA. I never noticed anything like what you're getting. I would have. The only thing that's different is that now I have the fast charge NN socket and that replaces a single USB rather than a Hella.

Interesting findings from today. My USB outlet remains on after the bike has shut down (ignition off, 60s or so, audible ‘click’ somewhere under the seat) if i then plug in an iphone, via a usb cable, it will charge for a second or two before the bike shuts the usb port down.

I’m guessing that the wireless head in standby mode isn’t pulling enough juice to make it shut down. I’m also guessing that this has something to do with it being a din port originally and used by the BMW charger that needs the ability to wake the bike up.

I’ve ordered a nav harness to USB from NN - which I’m hoping will function differently to the din port. I’ll report back once it’s installed.
