neutral safety switch troubleshooting

One of the most important safety features of your vehicle is the neutral safety switch, which is the mechanism that keeps your car from cranking in any gear other than park or neutral.
I will admit that this was not one of my better moments, but it did teach me a valuable lesson. While innocently sitting around one afternoon in my ’60 wagon, I accidentally hit the starter while the car was in gear. To my surprise, the engine fired, and the wagon lunged forward. Luckily, I was able to hit the brake prior to doing any damage. When I was able to breath again, I tried starting the engine again, only to find that the car would start in not only park or neutral, but in drive as well. This was an obvious surprise because when the shifter was installed, it worked properly by starting in only the park or neutral position.
