Question -
I have a 1975 Sportster that began missing from the front cylinder after I ride it about 10-15 minutes. The bike has an electronic ignition I installed several years ago. I also replaced the plugs recently. I am pretty sure it is fouling due to a faulty coil. What is the procedure to test a coil with an Ohm meter. My manual doesn't cover this.
Answer -
Do you have a duel fire or single fire ignition?

It's a Dyna S Dual Fire Ignition Model #12-319

Answer
You can test the coil, but I dont think that is the problem. Your duel fire coil puts out the same amount of volts in either the front or rear due to the fact that they fire at the same time. Check the posts where the spark plug wires go and see if they are coroded. If not hen I would replace the spark plug wires. You might have a bad wire.
If you want to test the coil. First remove it and the wires. You have to two posts where the wires go. This is the primary side. Connect the OHM meter to them. You should get about 2.5 to 3.0 OHMs. Not he secondary side is where the spark plug wires go. Connect the OHM meter to them and you should get around 10,000 to 12,500 OHMs.
Good luck and happy riding
