The alternator has nothing to do with your engine firing. Its job is to keep the battery charged.

You need to check for battery voltage at your coil. I would use the 12 volt coil. The hot wire from the ignition switch goes to the + terminal on the coil. With the points open & ignition switch on you should have battery voltage on the small terminals on the coil. Use a volt meter or test lite when checking. Rub those new points with some 400 wet or dry. If there's no voltage at the coil you need to check the ignition switch for voltage. Could be its defective or its not being fed battery voltage.

You need to check with your volt meter to see if there's voltage being fed to your ignition switch
could be a broken wire or a bad connection. You should've done this before changing parts. It's very easy to check for battery voltage. Hal

The garden was already sprouting when we hooked up the mid-mount shovel cultivators to the Pony. The seed bed was soft enough that the rear end would spin and slowly work its way to the downhill side of the gardens slight incline. From this, we learned our lesson sinc ... [Read Article]
