I recently installed the speed pro system in my car. I also determined that my alternator was toast. so I replaced it. Nothing more than bolt on and plug in. the alternator is working fine. The problem is that the car will start fine and run fine but when I turn the key off, the car keeps running. The only change I have made to the car is the addition of the fuel injection. all of the lugs on the ignition switch are hot when the car is running and I turn off the key. It is like the alternator is back feeding the ignition somehow. It worked fine when I had the carb on it. I have to disconnect the ignition feed wire to kill the engine.
just wanted to know if anyone else ran into this problem before I start hunting an electrical gremlin.
