Weird, but not unique in the world of Lucas. My tach bounces with the
clicks from the fuel pump, even with the engine off (key on). Continues
with engine on.
Rather than being a mechanical problem (linkage grabbing cable, etc),
Frank's situation sounds more like there's a wiring problem such that when
the brake circuit is closed upon depressing the pedal, the tach grounds out.
All this just goes to show that in the world of Lucas, everything is
interconnected in a ball of wire that's slowly sucking us all into a black
hole.
