My simple answer, without any explanation, would be yes. ;D
3 ohms is the minimum for a Dyna ( some might say 5 ohms is safer) or points on 12 volts
Bosch Blue Coils or Flamethrowers? Just bought the Bosch Blue at Advance Auto for $26.99. Only downside on a Lario is finding a place to put them.
I might say it after my 3 oh coil melted and took the Dyna box with it...
My Guzzi had 3 ohm coils on it for many years and then one coil failed...When in doubt ask Dyna...Dyna says the stock coils are fine...Many Guzzi's have 3.2 ohm coils...
Chuck would the coils be wired in series in your application?
I kind of *assumed* as much in the aero thread. Ok, I have one new green Dyna coil. Naturally, they're sold in pairs. ::) Anyone have one they want to sell?
Simply wrong, I guess. ;DAre the Dyna S ignitions (without black box) as sensitive as the Dyna III, as coil resistance goes? Maybe wouldn't need to go 5 Ω ?
Chuck I have one green Dyna single output 3 ohm coil. It's a good used one and it yours for the price of shipping... But according to the poster above Dyna says 5 ohm now ?
Ok if power is jumpered from one coil to the other they would be in series and you would add the ohms of each coil together 1.6 ohms.
From the Dyna FAQ:"For breaker points ignitions use 5.0 ohm coils or 3.0 ohm coils with a 1 to 2 ohm ballast resistor in series with the +12 volt supply wire to the coil. Dynatek cannot be responsible for ignition or coil problems that result from using a coil of incorrect primary resistance with a particular ignition system."
It's amazing that Americans came to the moon so many years ago. I suppose no coils in a rocket.
With this information I would want to start with 5 ohm coils and wire in a ballast resistor as well. That is probably why Guzziownr got a melted box with the 3 ohm coils not realizing that when wired in parallel they become 1.5 ohm coils.
