Further (mis)adventures in shoddy soldering…

So my module had been working solidly for +1 month. Then one fine day after a 30 minute drive, the ‘source’ abruptly switched over to radio and CD1 disappeared. A quick unplug & replug brought CD1 back, only to disappear again. I left the module unhooked overnight, and thereafter it seemed to operate for 10-30 minutes at a stretch before giving up the ghost. Note that the BT connection was always discoverable, and I could forget & pair the device.

Upon closer inspection, the CAN controller <-> resonator connection was a bit anemic, and a quick touch-up with the iron set things right (knock on wood).

One thing I noticed: one of the CAN LEDs lights up only faintly, and the other one doesn’t light up at all AFAICT. I can’t remember if this behavior has changed since I first built it. Is this normal/expected?
