'84 broncoII engine wiring complications

I have an 84 broncoII with a h.O 302 from an 86 mustang. Its fuel injected. The problem I'm having is if I turn on the lights, the wipers, the heater, or te electric fans kick on the engine turns off. But it starts right back up. It'll run just fine until something electrical is turned on. Its driving me insane! If anyone knows what the problem is I'd sure like to know?

Let's clarify what you are telling us.
If you turn on the lights, wipers, the heater or the A/C fan, the engine will stop. And then you need to restart the engine.
Does the engine slowly die or just stop working?
Is there any load put on the engine when this happens?
Is there anything else you can tell us to help us diagnose the problem?

The relays start clicking and the engine studders off. Dont have AC so I know thats not the problem. If anything electrical besides the fuel pump are turned on the engine studders off.

Take your car down to Autozone and get your alternator checked. I heard they will do it for free. I don't know if you need to remove it. Call and find out.
