I was planning on going for a ride the other day and found a "dead" battery. I believe some new gauges installed are the culprit (voltage gauge is always showing ~12 V).
Thinking about installing a "kill swich" on the end of my "+" battery cable to ensure there's no draw on the battery while the car is in storage.
I noticed the "+" lead has 2 wires (1 to the starter & 1 to something on the grill, perhaps the volt regulator??) See photo.
The question is should I splice this "kill switch" into the larger diameter wire (to the starter) or on the smaller wire, or both??
Thoughts??
