That wireless setup can be OK if it is set up properly.It is a little fussy to set up,but if you do it right it works fine.I put a new set of points in every year for a man that has one,I'll bet that setup is 15-18 years old.Without fail he manages to leave the key on some point in the summer,and it turns his point arm black.I really expected to see some arcing problems with that setup,because it just looks cheesy,but both setups I personally take care of show no signs of arcing whatsoever.I have a setup I took out of a customers car,he had trouble with it shorting out.It was not the fault of the setup,it was the owner/installer.
