Reply To: Testing voltage to the points on the Sportfour Imperial

I am not certain V=IxR  because  current in a coil is not a simple curent flow as in a  plain  old resistance .

A “coil”offers not only the pure wire resistance  it actually opposes  the flow  of current  because of  its  inductive resistance.

gets tricky  to make  current calculations  because the formula is a tad more complex .

If I recall….. in a capacitor …current actually moves faster while  voltage follows    later.

In a coil  voltage rises faster  while current is held up by the magnetci build-up in the coil (inductive reactance)

lots of good articles on the net on the subject…

that said play safe &  just reduce the current to protect  points and coils while  producing a good enough spark on the plugs.
