I relocated my battery in the trunk, but, in order to drag the car, I have to have a battery disconnect switch located on the back of the car which will kill the car when you disconnect the positive battery cable. This cannot work with stock 3-wire alternator, as the power for the alternator goes directly to the starter solenoid. When the car is running, you can totally disconnect the battery from the car, it will stay running, I know because I tried it.
With a 1-wire alternator, it will work because the alternator connects directly to the battery, not the starter solenoid. With the mustang, if I disconnect the power wire from the alternator to the solenoid, I can then start the car and run it off the battery, and then disconnect the battery to kill the car. Obviously, I cannot run the car like this as the battery would not be able to run the car very long without being recharged. I don't know if I can run the wire from the alternator all the way back and connect it directly to the battery or not, plus, I don't want to do this.
Does anybody know of any other solutions, or what other people are doing?
