Charging issues?

4 post disconnect; run a big wire to the trunk for the alt. Battery cable, BIG. Ground to frame, put a big, block to k-member ground in. Bypass amm, welding lead wiring, with soldered on connecters is good. Connecters at hardware store. Put in vise, clamp hard, then put wood on each side to hold it(less heat transfer) re-clamp, propane torch with RESIN solder from radio shack; plumbing solder won't work long.
