72 ford 3000 no spark at points

[sinclairville]

Hi, hope I can solve an issue with a 3 cylinder gas ford 3000. I bought a new coil and cap plugs but still no spark at points. What the heck. Does anyone have a diagram for the key back to the front of this tractor or a sight that may help me thanks Jon from Erie county ny

Have you checked the fuse yet?

To narrow down what might be wrong I would disconnect the power wire to the ignition coil. There are two terminals on a coil. One will have a wire going to the distributor. The other terminal is the one which receives power from the ignition switch. Remove the power wire and tape the end to prevent it shorting out on anything. Connect a similar sized wire to the positive battery terminal (I am assuming you have a negative ground system) Just before you try and start the tractor connect the other end of the wire to the coil. Don't leave this wire connected for long periods when the tractor is not running as you can overheat the coil. If the tractor starts or you have spark at the plugs you now know that your problem is in the power supply to the coil.
Try that test and post again and we will try and help further if necessary. It may not be a good idea to run the tractor for more than a few minutes once it starts on this wire as your ignition system may be supplied with reduced voltage after it starts and in this temporary test arrangement you are supplying 12 volts to the coil.
