Aux socket draining the battery?
Posted: Tue Oct 10, 2023 11:16 pm
Hi all!
On my 2014 R1200RR (LC / K52), I added a USB charging port by repurposing the Hella plug on the throttle side fairing.
I disconnected the wires at the back of the Hella plug and connected a 12v-to-5v USB adaptor.
After completing the instal, everything worked fine so I buttoned everything up and went for a ride.
3 days later, the battery would power up the dash and try to turn the engine over but just couldn't start it due to low power.
There was nothing left connected to the newly installed USB cable during those 3 days.
BTY, the bike's battery was changed less that 1 year ago and has been very reliable so far, no indication of failing or anything lately.
I'm wondering if the small draw of the 12v-5v connector was sufficient to keep the circuit live after the usual 60 seconds after turning the key off?
I vaguely remember reading something of this nature on a forum but can't find it now.
1 last thing that was weird and probably related to the issue: when I turned off the bike with my phone pluged in my new USB port, I saw it flashing the charging / pluged in notification repetedly for a little while. When the engine was running, the phone was charging like normal.
Thanks in advance for any ideas!
