Rear Position Light Fault???

[coach]

Installed an aftermarket Canadian Brake/turn indicator a couple days ago that I have had on my past 3 bikes and all went well until I started out for a ride this morning.  A minute after starting the bike and riding off (not right away), I get a message "Rear Position Light Fault" and the rear taillight is out as is the aftermarket light kit.  Turn off the key and restart the bike and everything works fine for about 45-60 seconds and then the fault message comes up again. I ran into a similar issue with my 2017 R1200GSw due to the BMW CanBus system but someone on the GS site had a work around.  Anyone know a similar fix for my 2021 Tiger 900 GT?

Never mind, I figured it out after pulling out my notes from the R1200GS installation.  Just in case anyone else runs into this issue here's the problem & the fix:

Turns out for the switched power lead I also had the Denali aftermarket driving lights wired off the same switched Brake light power lead.  The Triumph system couldn't handle the load of both aftermarket units so it shut everything down.  I turned off the Denali lights and went for a ~25 mile ride and no warning message came up.  When I got within a mile of home I switched the Denali lights on and the warning light came on.  I'll have to find a new switched power lead for the aftermarket rear brake/turn signal lights...probably tap off the rear powerlet accessory socket under the pillion seat.

I believe the power outlet you're referring to isn't switched, always live.

The powerlet outlet up front by the steering head is always live, but the one in the back under the pillion seat is switched on my bike.  Not sure if that's the way on all T900's, but mine is.  However if you have a better source please let me know exactly where it is as that rear powerlet socket wiring is going to be hard to get to. Too nice of weather now to start that job...a good rainy day project.  Thanks

I may have misspoken coach, Just noticed you're referring to a 900. I have no experience with that model.

Hey Coach - Installing an Admore tailight on my Tiger now.
Thanks for the heads up on that 'fault' issue. Do you remember which wires you hooked where? I get the power and ground but curious about the turn and actual brake light circuits and which factory wires you chose.
Thanks!

Would it be possible to use the switched brake light feed to power a relay which then powers your auxiliary lights using a direct feed from the battery (or other suitable power take off point)?

You could try one of these

If you set it up as switched live you will only have one connection to the bike electrical system and no CANbus issues
