fuse

I just started my first big project, a 51 Jeepster mounted on a 2wd s10 (Jeepster51/10.) I got it as "mostly complete," it's a runner but needs a lot of electrical work. Nothings organized, just a rats nest under the dash, with the occasional inline fuse holder. I've got all winter, so...

My battery continues to fail. Something is pulling on the battery. Mechanic removed the accessory fuse but nothing works. Haven't driven car in months. We know that it may be electrical. Any help or feedback is greatly appreciated.
