Diagnosing dead battery
 

Looking for some other opinions on what might be killing my battery.


Last Friday night I installed the TapTurn flasher relay and the DiodeDynamics Tail-as-Turn module with replacement backup LEDs in the turn signal position.

The following day I tried to start the car and found I had a completely dead battery. I couldn't get the windows or trunk to function without a jump start.

Would either of the two mods above cause a parasitic drain on the battery or is the dead battery just a coincidence? The tail-as-turn module is the new version with the built-in resistor. Could there be a short across this resistor that is draining the battery?

Thanks!

Maybe this should be moved to Cosmetic Modification... sorry mods. :bonk:
