I've got some kind of weird electrical problem that is presenting in several intermittent ways.

I suspect that the positive wire to my coil is probably the most serious problem leading to stalling and bucking under load (randomly). The other issues seems to be a wiring fault near my fuel gauge terminal as signal, fan, and indicator lights refuse to work and the amp light comes on. I'm still tracing this problem and think I know where the fault lies.

Anyway, I was poring over the wiring diagrams for the 120 series, and noticed that on the Alternator-equipped 122 (guessing the 1969-1970 European models) the coil+ is powered from the #2 fuse. Those models had a different ignition setup with a steering wheel lock, so I guess there was no armored coil wire on those models and a different anti-theft concept...

Aside from theft concerns are there any issues with powering coil from the #2 fuse? Should upgrade to a higher amperage fuse, should I use a 12 gauge or thicker wire for this?

If this works fine, is there anything (besides installing a "club") that I should do to discourage theft?
