What will happen if I dont plug the computer into alternator?

I bought a new 200 amp ford alternator for a nissan but it didnt come with an adapter so i cant plug the computer in until i get the plug. I have the main power plugged in and the ground but thats it. What will happen if the computer isnt plugged in?

Well first, it should be a Nissan alternator, or an OEM or after market alternator ( call your local part store). Second, there is no adapter. Third you need the computer plugged in because the circuit will be open. Also the alternator will not charge the battery when the car is running so you will continuously get a dead battery.

Reply:By computer, I am assuming you mean the voltage regulator. And the answer is no, it will NOT work, at least it will not work correctly The alternator works by a feedback circuit, as the alternator output voltage goes up, the excitement voltage goes down to prevent overcharge. Depending on the type pf feedback used in this particular vehicle, it will either NOT work at all or charge at the maximum rate Like I said, it will not work correctly.
Reply:I have a suspicion that the nissan alternator is regulated by the computer and The Ford one has an internal regulator.If that's the case there is an incompatability problem here that should be resolved before something really bad happens.
Reply:It probably won't run.
