i have and 84 gt w/ a ready to run distributor. i am having problems shutting down the engine once it fires. the key wont turn it off. i have to shut the choke by hand to shut it down. when the engine is running i have 14.4 volts on the positive side of the coil and 12.1 on the negative side. i have a resisted wire filter on the negative side which i had sent to me from MSD. doesn't 12 volts seem high and could that keep the engine running. or coud it be an ignition switch? also after it runs for about 5 mins. it just dies. it starts right back up but dies again quickly.

Hello.:) First let me say that I am far more familiar with 65/66 cars than I am with 84 models.But, 14.4 is high. That is straight output from the alternator.You probably have a regulator problem.I believe that your alternator is internally regulated, so that would call for replacing the alternator.The car starts and runs fine for a few minutes and then has trouble would also be accounted for by excessive voltage to the coil. It is getting hot and breaking down on you.The not shutting off thing is probably the ignition switch. Is this a car that you have bought recently or have you had it for a while? You might want to have somebody run the codes on the car and see what the EEC says is wrong with it.The car will tell you where it hurts if you ask it right.Hope that helps.:)
