In the past few weeks I had some starting and charging issues. I thought I had a short somewhere, or bad alternator, or bad battery. I had the battery replaced under warranty, the alternator is charging, mid 13's, not great but works, and finally I started looking at the starter and found the nut on the positive lead from the battery loose on the post. I fixed that and the car was starting like new for few days. This morning I went to start it and nothing happens. I have over 12 v on the battery, but I get nothing on the ignition feed to the starter. I jumped the starter posts and the car started right away. But what are the places I need to look to see where I am loosing the ignition signal ? I checked the fuse and the relay under the hood on the fuse box. What would be the signs of bad ignition switch ? And where is the neutral switch ? What else to look for ????? I am puzzled.
