SOURCE: i want to change my 2006 HD 1200R from fuel

your asking for a lot of problems as the system u have is toatally dependent on the computer.... u would have to change so many things just for ignition the crank needs to be set up for some sort of electronic ignition as this system uses a crank sensor to the ecu to set up timing and spark as well as o2 sensors and an electric fuel pump manifold air pressure switch these and other sensors tell the ignition what to do it would be easier and less expensive to buy an earlier carbuerated bike

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
Steve

Also hook up a scan tool an see if it will communicate with the PCM . That's how you check the PCM ! Also check the constant control relay module , these go bad an they have fuel pump relay , power hold relay , this powers up fuel injectors an ignition system !

You may have to get a manual to find the color codes. But only one cable goes to the fuel gauge sender it travels in the wiring loom to one side of the fuel gauge, and from the other side to the ignition switch.

1987 chevy r20 carb with electric fuel injection


I would check the wires that make the injector function to see how much power is going to them (using a multimeter). Now check the wires on the injector that is not working and see if you have power there. If you do then you have a bad injector. I don't think you do since you said that you switch wires and you are getting fuel at that injector. Check your wiring harness for shorted out wires. It doesn't make sense for one side to be working and the other not to be. I don't think it is a problem with your ECU, but it may be. See what colors the wires are going to your injectors and trace them back to the ECU, a wiring diagram would help. You need to check to see if you are getting power from the control module to the harness. I believe, however, you are experience a shorted out wire somewhere in the harness. That is where I would start. If you confirm you are getting power to the control module, but you are losing it somewhere in the harness it may be easier to just run a new set of wires instead of tearing apart the harness.

Fuel injecter fuse blow imeditaly when ignition turn on


sounds like a short in the wiring from the fuse and the fuel injector junction block. GM like most fuel injection systems control injector firing by the computer providing ground to each injector in pairs or individually. The fuel injector fuse provides power to the injectors using splices therefore enabling one wire to feed 6 injectors. A shorted wire at any of these wires will blow the fuse. On one rare incident I found a faulty computer caused the fuse to blow. A shorted injector will just cause a rough running problem due to the injector stuck either open or closed.
