Angry Starter system

I need some help. I replaced a solenoid on a 93' Aerostar but when I hooked the new one up, I had no electric. I was told to put the 2 battery leads plus the 2 auxilliary leads on one post and the starter lead on the other. Got the electric back but found the starter motor was bad. Replaced that but when I hooked the neg battery terminal back up, the starter motor started running. Any help would be greatly appreciated!

You've got some wires crossed somwhere. Check autolibrary for proper installation and connection:

Generally with an external solenoid the positive batt cable goes to one side of the solenoid (large terminal) and the other large terminal has the main cable that goes to the large terminal on the starter. The two small terminals are what connect to the ignition switch. If you have both the battery cable and the starter cable on the same side of the solenoid, you are making a direct 12v connection to the starter.

Agree with TowGuy. Also whose parts are you using? If not genuine Ford, the problem could lie here. Some aftermarket parts quality is very poor.

starter system

the vehicle I'm inquiring about is the '93 Aerostar with the 3.0 litre engine. The thing that confuses me is that there are 2 leads coming from the battery and 3 leads comming from the other side of the solenoid. I've put the 2 leads from the battery on the battery side and then put one lead at a time on the starter side and every time I touched the negative terminal with the connection, the starter motor would start running. I don't know where to go from there and I sure can't pay a 2 or 300 dollar service bill to find out.

You could easily have a bad solenoid or a stuck starter.

What brand of parts are you using? Use Ford/Motorcraft ones.

Put the battery lead on the right side of the solenoid (away from the battery) and the starter wires on the left looking at it from the front like you are standing there mounting it. Try switching the 2 small leads as well your problem could lie here.
Hope this helps ya,
