GSD tail light out

[asadc]

Hi folks,
Anyone got any ideas on quick troubleshooting things I can try for a GSD tail light that is out? No brake lights, no regular light (headlight works, and using the handlebar controls for the headlight (both Tern and Bosch light buttons) doesn't do anything). This is a ~3 year old R14 if that helps. The bike was on a work stand (and supported by a stool) for a couple weeks during a -15 C / 5 F cold spell - it warmed up this week and I put the rear tire back on with studded winter tires and went for a ride and no rear light. I'm not 100% sure though if it happened during the time it was on the stand. Any reason popping back wheel on and off could do it? I did struggle a bit more than usual to get the wheel back in...

Certainly not going to retrace/rerun the entire line, will happily take it back to the Tern dealer / LBS for that.

I've replaced both front and rear headlights on my QH and my husband's NBD which were rather easy to do, so I would first suggest checking the connection to the rear light as the front light works and the console isn't showing an error. It could just be a loose wire/connection. If you have the tools, you could turn the bike on and check the rear light wire to see if it is carrying a charge if it is not a loose connection to the rear light as, if that's the case, you'll need to have it serviced by your local dealer or bike shop. HTH.
