Not too much, if you are a fair mechanic. You probably should get a service manual tho. Basically, you remove the foot pegs and anything in the way, remove shifter, clutch cable. Drain the trans oil, then pull the cover. A couple parts may fall out, that's why I suggested a service manual.

SOURCE: specs and oil capacity

Most owners of the old Ironheads try to use the oils that were used when they were built. They use straight 50 weight when the weather is cold and 60 weight when temps are hot. But, one could use 10W50 oil in them. I would not use synthetic as any oil leaks will intensify with the use of synthetic oil. The XLH, XLX, and XLS tanks hold three quarts with the exception of the XR1000 which hold two quarts.

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 wd4ity@bellsouth.net .

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: I have a 1979 harley

The original wires, one blue and one white, were with the points ignition. The white wire should be the "Hot" wire. Now, look at your wiring diagram. The two white wires should go together to one side of the coil and the blue to the other. There is no positive or negative side of the coil, just two small primary winding terminals. Make sure the white wire from the ignition system is the "hot" or power wire for 12 volts. If you connect the ignition unit up backwards, it will damage it. To make sure the white wire on the bike is the hot wire, simply turn the ignition switch on and check this wire with a test light or volt meter. It should show battery voltage on it. That should be your setup, two white wires on one end of the coil and a blue wire on the other.

Good Luck

No, you have said too little. This year is long before my expertise but what do you mean by hard wired, and I am at a loss as to an ignition module for a 1980 model that would need to be mounted to the bottom of a battery tray. It would be very surprising to me that any electronics would be mounted under a battery tray especially if there was any chance of any battery acid, corrosion from a wet lead acid battery that would go with a 1980 motorcycle etc possible to contaminate the electronic device. An electronic ignition module could be mounted anywhere it was secure, protected from moisture, battery acid, excess vibration etc and it was adequately/properly grounded.

I have a 1979 harley davidson ironhead sportster 1000 cc . I have had 3 condensors, 2 sets of points installed this riding season. What might be causing this issue ?


The '79 model came with electronic ignition and someone has converted it back to a points type ignition system. I'm betting that they did not change the coil. Check the resistance of the primary of the coil. It should be between 5-6 Ohms of resistance for use with points. A coil designed for use with an electronic igntion uses a coild with 2-3 ohms of resistance in the primary winding.

good luck

Double check your wiring---On a dual fire coil, the Orange and Black wires will connect together to the negative side of the coil... using a single fire coil, the Orange wire will be used for the front cylinder negative terminal and the Black for the rear cylinder negative terminal ...hope this helps.

79 harley ironhead 1000cc xlh no spark from coil coil is good and im geting power to both sides of coil


It sounds like your sensor in the timer cavity on the right side of the engine is bad. Disconnect the blue wire from the coil. Take a spark plug out of the engine, put it back in the spark plug wire, and lay it on the head. Turn the switch on and momentarily touch the blue wire to the coil. When you take the wire off of the coil, you should see a spark at the plug. The purpose of the sensor in the timer cavity is to stop the flow of current in the coil and initiate a spark.

Good Luck
