Generally speaking, when troubleshooting electrical networks, you can either start at the far end and trace it back to the battery, or start at the battery and trace forward.  Since neither coil is firing, either both sets of points are bad or out of adjustment (which could happen).  If you were tracing back, verify the points are good, and you are getting the voltage changes you expect.  If they are there, then move up the cables (blue and yellow) to the coil connections.  Again, unless both are disconnected, it's unlikely both coils are bad.  On the other side of the coil should be the connection to the battery through a fuse.  This is why I suspect there's a blown fuse.  One of the coil connections should go back to the +12V on the battery.  I just can't remember which.
