I just did the 3G alternator upgrade to my 89 mustang gt. It started fine on the first try. The next time I tried to start it the car went crazy. The key is out of the car and as long as the battery is connected it will try and start. The only way to make it stop is to disconnect the battery. Any suggestions?

Yeah,your ignition solenoid is probably stuck.The solenoid is that black round cylinder looking piece bolted to the inner fender next to the battery and has a mass of wires connected to it.Try tapping mildly on the side of the solenoid with something hard like a screwdriver or hammer.Do this several times then reconnect the battery.If this fails to work then try once again.Your best bet would be to replace it.They are only about $7 - $10.Doesn't matter where you get them,it will always be the same brand.No one else makes them (I think summit may have a HD one).And yes,they are quite notorious for sticking like that.Especially if the car sits a lot.
Something else you could do to help prevent this.Upgrade your starter to a high torque mini starter.These are the ones they used on the later 91-93 foxes.They draw much less current and are much lighter than that MASS that's currently in there.They are also quieter.
