Searon Tiny Tach
Mine arrived today, silly question:-
The induction cable that comes from the unit to wrap around the sparkplug lead, is a bog standard twin insulated flex with red & black cores. The instructions state "No ground wire required" so, do you wrap the whole insulated black cable around the HT lead, i.e. just treat the insulated twin cable as a single wire, or do you strip the insulation back & wrap the red or black inner core around the HT lead. I'm assuming it's the former, but the instructions aren't clear.
