Ah. Read it sooner than later. The ammeter will normally only show a high draw to that circuit when the engine is off. Once the engine is running, power comes from alternator and the ammeter doesn't show flow from the alternator. Being a fused circuit, at least its reasonable well protected.
Some good ideas in the article. I like Nacho's method, similar to the Chrysler approach mentioned in that article. Nacho ran a parallel wire from the battery, and another one from the alternator directly to the back of the ammeter. They go through a grommet in the firewall - no additional connectors or junctions and no splicing needed.
Did I do it? no. I put the headlights on relays, which was the one circuit that I had problems with. Very little other electric loads in my car.
Wire colors. If you're near a boat/marine supply place, the ones around here have a very good selection of wire insulation colors, cut to any lengths wanted.
