Motorcycle Repair: Coil / ignition, revtech motor, wire coil

Question
What should the ohms read across the plug towers on a single fire three wire coil.I have a 2003 revtech 100 ci motor on my Softail it keeps dropping fire to the rear cyl. If one cyl fires is the electronic ignition good or can it drop fire to only one.Is the single dot on the flywheel TDC and the two dots the advanced mark.
Thanks
Mike

Answer
you should be showing aprox 3 ohms. I would check the plug wire to make sure its good. Generally, if the coil and plug wire is good then then the ignition is to blame.
As to the timing mark on yoru revtech motor, I am not sure about the timing mark on it. You would have to check with revtech on that one
Good luck and happy riding
