6 V coils?

Please,
had the 1967 points types coils 6V?.
Thank you.

What is your question? Two 6v coils connected in series are standard on my '74 850.

Sounds unlikely. Do you have a manual and parts book?

Sounds unlikely.

Isn’t it two six volt coils in separate circuits, each in series with a ballast resistor?

12 volt coils otherwise you need a ballast resistor, pre 1970 Commando's also had 12v coils without a ballast resistor.

Sorry,
my 1967 33 CSR , original harness, has points with condensers into the same plate.
Question is if coils was 2x12 V joined in parallel?.
Thanks.

Best answer is one Japanese double-ended 12 volt coil. Every electrical connection provides an opportunity for high resistance or interruption,

A 12 V positive earth system with two coils and two sets of points, has two 12 V coils. The - terminals of both coils are connected to the switched side of the ignition switch. That part is “in parallel.”

The + terminal of each coil is connected to its respective set of points, which make and break the circuit to frame and battery +. I don’t call that part “parallel.”

Some vehicles with electric starters use 6V coils in a 12V system, with a resistor in circuit, called a “ballast resistor.”

G15's and Atlas/650SS/Mercury made between March 1967 and 1969 were equipped with 12V coils (LU45110, 48mm diameter).
A wiring diagram is available in the 1967-70 workshop manual.
