You need that condenser (capacitor). Go to the Accel catalog or web-site and look up that coil and see what the required matching condenser is. The condenser value (uf) is chosen to match the inductance of the coil primary winding. The condenser can almost be mounted anywhere so keep looking for it. It is a required component so if it is missing, install one.
It is important to realize that coils are designed to be used for a particular ignition. A points (kettering) system coil can be used in a CDI application, but a CDI coil can not be used in a points system. The primary resistance determines if a ballast resistor must be used. You can not just take any coil and hook it up in any application.
Get the specs for that coil and upload them so all can see. If the coil you are using is designed for a HD POINTS application, then maybe all you need is a capacitor.
