That's interesting, thanks for clearing up my confusion.
It does raise another question, though.
I am using a pair of 1.5 ohm Dyna Coils on a 100GS - wired in series. Should I put these in parallel as the electronics seem to handle the load ?
Some background:
When I twin-plugged my R80RT, I used a pair of coils supplied by Motobins.
I made up a mounting bracket and wired them in parallel.
The bike ran, but not well.
I contacted Motobins who advised that they should be wired in series. I changed the wiring and immediately had problems. Investigation showed that one coil was 'open circuit'.
I didn't like the coils or their fittings and as I suspected that I had fried them by running them at 12v I bought a pair of Dyna Coils from
MotorWorks, wired them in parallel and have had no trouble since.
That is why I have been a bit wary about adding non-OE coils.
The Motobins coils looked like this:
I'll keep my pair of Dyna coils wired in series unless someone can advise otherwise.
Thanks again.
Bob.
