How do I check for a draw, i.e. battery keeps dying
One very easy way is to put a light in line at the positive terminal. If
it lights, you have a draw. You then pull one fuse at a time until the
light goes out. This narrows down to one circuit where the draw is.

I suspect the draw is comming from an accessory I installed this summer, but can't be sure. Accessories are Alpine alarm and power amplifier. car is 1993 bmw 320i. I'm thinking of putting an"under hood" trickle charger, is this a bad idea?
