SOURCE: Needing a wiring diagram for a 1981 HArley
I have one for an '84 model. About the only difference is the 84 model had an alternator instead of a generator. Other than that, it's about the same. contact me at [email protected]. I'll try to scan a copy from my service manual and shoot it to you.
SOURCE: I need a wiring diagram for a electronic ignition module.
If I understand correctly, Your bike has points in it now and you want to go to electronic ignition. If that's what you want to do, I would suggest that you go with one of the aftermarket ignition units. They're more versatile, costs less, and easier to install.
There are two types available. Your bike has a mechanical timing advance unit behind the points breaker plate. One type of electronic unit eliminates this mechanical part and makes the system truly maintenance free while the other type retains the mechanical advance unit and cost less. A prime example is Crane Cam's HI-1 unit that retains the mechanical advance and their HI-4 unit that eliminates it. Most bikes made after 1984 do not have the mechanical advance units. Since your bike does not have any of the original components left on it, I would suggest that you get one of the units that goes in the "nose cone" of the engine. It simply replaces the everything in there if you get the unit that does not use the mechanical advance. The Mechanical advance units are prone to wear and since no one ever services them, I'd suggest getting rid of it. You'll have to purchase a "timing cup" from Harley, costs about $20, a lot less than $100 bucks for needle bearing mechanical advance unit. Get the shorter screw that goes with it as well.
All you have to have with either unit is a "hot" wire going to the coil. The coil must have a primary resistance of somewhere around 3-4 ohms where a points type coil has a primary resistance of 4-6 ohms. To determine the resistance of your coil use a Digital Volt Ohm Meter and measure the resistance between the two small terminals on the coil. To wire the ignition units is usually just a two or three wire hookup that is very simple. They all come with wiring instructions.
Now, the next thing is whether you wish to stick with "dual fire" ignition or go to "single fire" ignition. Dual fire is the system that almost all Harley's come equipped with from the factory. In this type of system, both spark plugs fire when the pistons are top dead center. Since one piston is on the exhaust stroke, that spark is of no consequence and therefore is considered a 'wasted spark". In a "single fire" system, the spark plugs fire independently when each piston comes to TDC on the compression stroke. It requires either two coils or a "two in one" type coil. This added coil increases the cost of the system and to be honest with you, I cannot tell a difference between the two systems. With that in mind, I opt to go with the less expensive and simplier "dual fire" system.

Ok, this will get you started. Installing an electronic ignition system in an older Harley is easy to do. The difficult part is deciding which one to go with. Once you do that, no problem. If you have anymore questions, drop me a line at [email protected] .
To see how to hook up one of the units, go to their website and look for a "Technical" page. Go to that page and look for "installation Instructions". Print them out and it'll tell you everything you need to know. If not, I've got some different types of systems installation instructions that I can scan and send to you.
Good Luck

SOURCE: 1974 Harley Davidson SPORTSTER TURN SIGNAL WIRING
I can help you with the wiring diagram but it will be the complete diagram. I have never seen just a turn signal only type wiring diagram. But, there's nothing to a '74 model Ironhead turn signal system.
All the wires for the system were gray but had these little "colored rubber bands" on the ends of the wires near the signal lights. The violet bands were for the left side and the brown bands were for the right side turn signals
Now, I cannot send the wiring diagram through this forum as it will not allow for an attachment. If you will contact me directly, I'll send you a wiring diagram as a jpeg attachment via e-mail. My address is [email protected].
Good luck
Steve
