Apologies for the thread necro.
Battery light popped on for me last night on my way home. My initial thought is that it is battery/wiring harness shifting. Seems that the oem battery is sliding aft in the mount. Battery light flickers (not blinks) at low speeds/stop, then solid at higher speeds.
Measured 11.7 V on the radar detector plugged into the cabin 12v connection, battery reads 12.33 V across the terminals, and 11.8 V across the terminals at idle.
Sounds like I should be looking for a connection/supply problem, yeah?
I go trace the wires/check fuses now. My assumption is that it won't be something obvious to me & will have to make a visit to the shop, but any tips on items to check would be awesome.
Edit: N/A car...realize this was an S/C thread but seemed more recent/appropriate than the other thread on the topic.

Symptoms seems similar to that, though & I'm referencing those troubleshooting tips.
