Regrettably, you failed to tell me the year and model of your bike. More importantly, the model of your ignition module. But, all is not lost. Go to this site and select "ignition" modules for your model bike. Then look for "installation instructions" for the model ignition unit you have.

Let me know if you don't find the information you need. I'll need your year and model bike as well as the model number on your HI-4 unit.

Good Luck

If my 1981 flt has points ignition, then I don't have to purchase a centrifugal advance to convert to electronic ignition. Is this correct?

Hi, Douglas it all depends on the cost of electronic ignition that you purchase most brands use a mechanical advance for cost reasons on some of its models and then offer straight electronic ignition without a mechanical advance for more money if you upgrade to a stock Harley electronic ignition no problem do your homework and find something that you and your wallet are comfortable with check out Crane, Dynatek and Compufire for more information about your issue and free downloads that you will need please visit the websites below, and for specific information or questions, please feel free to contact me at Good luck and have a nice day.

Contact Crane for wiring diagram - although they should have supplied one with the product. You may not have connected the tach wire to the correct output from the ignition module.

Are dual and single fire coils interchangeable?

If you have 3 wires it's most likely a single fire coil. Meaning one spark per cylinder. A dual fire will typically have two wires and fire both cylinders at the same time, but only one will produce power since it's on the compression stroke and the other cylinder isn't.

Need wiring schematic for Crane Hi-4 dual fire elec system for H-D chopper. Unable to find diagram for this. all my online searches go nowhere

Try a look at . In the mean time and whilst it is loading, a few thoughts;

A lot of folks in the club know far more about Shovels than me.
But from my own observations and experiences....and asking around over the years. And now thatI have a points bike:

POINTS are good, can be reliable, but do wear out. the good news is that you will get warning, as components (weights etc) slowly disintegrate. Bike will start to run rough, hard to kick. Points are cheap, you can replace at side of road.

Those who religiously stick to points always use the ''side of the road'' argument. This seems mostly to stem from the late 1978 through the early 1980s when Harley first developed electronic ignitions. And frankly, their first efforts sucked, by general consensus. But since the advent of the Evo's V-Fire III version the factory and aftermarket ignitions have been fairly bulletproof for tens of thousands of miles.

CRANE Hi4 is but one of several aftermarket ignition systems that can retrofit into nosecone (or externally) on points-equipped or factory-ignition Evos and Shovels. Others like Daytona, Dyna, TwinTec, etc. I only know the Hi4, so....

The Crane has a switch that allows very easy kickstarting. When set thus, the plugs attempt to fire on the first turn of the flywheels, as opposed to the stock set-up which only fires after the flywheels turn a couple of times. That makes an Evo, for instance, very tough to kickstart if fitted with kicker and stock ignition.

With good plugs and even just static timed (there is an LED on the module that permits this), the Hi4 is brilliant. Worked so well on my 4spd Evo i actually removed all electric start parts 7-8 years ago.

There were a few issues on some early nosecone Hi4 modules that overheated, but I never that that prob.

After ten years and 50,000 miles, my first Hi4 failed 2-3 years ago. I got some help from the Crane tech line, and diagnosed it, put the results in Tech Tips on this site.

The replacement took 20min to fix, i just put it in the same (timing) spot as the first one, and bike kicked up 2nd attempt.

The absolute beauty of the Crane Hi4 is set and FORGET. Until it did die, i never even had to open the points cover. It always kickstarted, unless other factors weighed in.

My Wide Glide has points, but I am just about to pull them for a Hi4.

The guys at the one Shovel bazaar here in Melbourne endlessly recommend fitting a Hi4. They all have them in their own bikes, and when asked their opinion of points they say: ''comparatively? ****. There is no need to run points these days.''

Everyone has an opinion on this of course. But I am going for total peace of mind. I'll no doubt be on the roadside due to something else on the Shovel some day, so i may as well eliminate potential problems......
