Could the alternator cause your 1991 Lincoln Town Car to die when the AC is turned on?

Not really. Whenever you switch the lever to A/C, it sends a signal over to the PCM and it in turn not only energizes the A/C clutch, but it also bumps the idle up with the IAC valve because of the additional load placed on the engine. So the problem could become complicated.

If your battery is not up to par could cause this and of course a short in the system too.

Sometimes a weak diode within the alternator can cause this. Your alternator may test out fine but have it checked anyway. I hope this helps you. Mark get your alternator checked out as it sounds to me like its on the way out

Cause he turned has back on the US when he freed slaves and other things

The computer controls the alternator. If the charging system is malfunctioning, that could be the cause of the weak battery.The computer controls the alternator. If the charging system is malfunctioning, that could be the cause of the weak battery.

Weak alternator? Bad Voltage regulator? Alternator belt slipping?

Yes it could, a alternator has air passages in its case to allow for cooling. If those holes are blocked the alt. could overheat and fail.

The alternator is belt driven and so is the water pump but that is where the correlation ends. There is no way a bad alternator could cause a water pump to go bad unless the alternator pulley was warped. Then there is a small chance.

If the fuel pump is causing a fuse to burn up on a Lincoln, perhaps it is because the fuel pump is not shutting off when it should. It could be running after the car is turned off.

There are a few things that could cause this problem. It could be the wiring to the alternator, the alternator solenoid, or the wiring.?รฆ

No a bad batery could not cause the alternator to go bad .only if a big short happened to the battery and melted the cells in to a short inside the batt

Perhaps the alternator is bad, and the lights bring the battery voltage down too far. You could also have a loose connection at the battery.

i think you should try a new alternator buddy. u shold be getting 14+ volts maybe that will work :)

A bad thermostat can cause overheating in a Nissan Frontier when the air conditioning is turned on. A bad compressor can also cause this.

Hey Dee ann==Not simply idleing the engine. If you had an extra load on it to cause it to overheat this could cause it. GoodluckJoe

About the only thing to cause an alternator short is an internal fault. One other posibillity is if the wiring connection is the bolt on type as opposed to the block push on type the main battery to alternator cable is shorting there

The ground cable, on the battery may need to be tightened or cleaned. The alternator voltage regulator may need to be replaced.

No it can not. If the belt is missing that could cause it to run hot.

the battery could have a dead cell, this could cause it to not charge. Have the battery tested to be sure.
