When I changed my ignition system from a Mallory single point to MSD electronic I now get what one mechanic called "run out". Now when I go to shut the motor off it keeps running but all the other electrical items shut down. I ran a second ciruit with a separate switch to the MSD so I can kill the motor as a temporary fix. One person says "get a two circuit ingnition switch". Another person told me I need to have the alternator checked that there is a resister or diode blown that is letting power from the alternator feed the ignition which it turn won't allow me to kill the motor with my original single ingnition switch.
Has anyone run into this problem and what is the best cure? I really hate having two ingnition switches and I think it could be dangerous if you need to shut off fast. eek! I heard this is a common problem when switching to MSD.
Thanks for the help.
