K1200S battery going flat after a few days
« on: September 26, 2025, 04:56:33 PM »
Hi Guys I've a problem with the bike battery going flat after a few days.
With a clamp meter attached it is always drawing 78 Miliamps.
I've removed the vehicle control module and the current drops to 5 millamp which is quite acceptable.
i can then start the bike up engine runs Ok then switch it off ,current is about 30 millamps then drops to 5 milliamps as the ECU drops into sleep mode.
Reconnect the module still only 5 milliamps.
Start bike up then switch off current stays at 78 millamps.
It would seem the control module is not dropping into sleep mode or could something be stopping it going into sleep mode ?.
No fault lights bike starts and runs fine.
No accessories complete standard bike.
Disconnect the battery bike can be left for over a month.
Not used my GS-911 for anything other than basic service work.
Is there any diagnostics on the GS-911 to watch the Can bus for activity etc to see if something is waking it up ?.
Or has anyone else had or heard of this fault ?.
Also is the vehicle control module paired to the ECU and key so i can just swap it for another unit to test .

Thanks in Advace
