I hate it, but I'm getting better at it.
My sons '68 FB slowly drains the battery. 10 days'll go by and the Optima Red Top won't have enough juice to crank the motor. It's done this since the "professional" audio guys installed his sound system/alarm/motion sensors/radar detector/and "another" radar device. IMO, their work was second rate. One of the "black boxes" was just stuffed up under the dash and became entangled in the WS wiper linkage. I had to re-do some of their work and wasn't too thrilled. With him living overseas and not driving the car, this hasn't really been an issue, but I'd like to correct this before he returns. I've been leaving the trunk mounted battery disconnected from the cars positive lead and keeping the battery on a trickle charger to keep it fresh. I've noticed when I connect the positive cable to the battery that there is a rather large "spark". This tells me that something is placing an immediate drain on the battery while everything, but (supposedly) the stereo presets/memory should be "off".
What's the best way forward here?
Start pulling individual fuses for all of the different electrical components and see which disconnected circuit stops the positive cable from sparking when it's connected to the battery?
