Question on 1700 ignition
I'm thinking of buying a tach for my 2011 Nomad 1700. I've searched this forum but have been unable to determine if the 1700's are dual fire or single fire.
Now before the discussion gets started, I understand what dual fire ignitions and single fire ignitions are, I have dealt with both on Harleys. But my question is which is the 1700 dual fire or single fire ?
I could just order a dual fire tach and if it reads 1/2 what it should, then I could buy the single fire adapter, but figured you guys could tell me before hand.
I looked at the wiring diagram and it's got two coils each with it's own separate ECU pin. This seems like overkill for a true dual fire system. But the 1600s had two coils also and guys have told me they were dual fire.
So all you guys that bought tachs for your 1700s, where they calibrated for dual fire and if so did you have to buy a single fire adaptor.
If you did not buy a single fire adapter did you wire it to just one coil (at the negative primary terminal) or both coils ?
