Glad to be of help. Have you checked the switch in the trunk? If the wires are getting hot, it sounds like something is shorting out. The junk yard compressor may be bad.
I'm switching to Q&A format to be notified of your response.
When I changed the compressor, what would cause the wires to get hot? Well, being on a limited budget..$32.00 is better than $150.00. But then, you get what you pay for.
On the original compressor the wires did not get hot. Does this rule out a bad ground? Now when I replaced the short before, I cut the wire but I did not have a sodering iron and I used crumps. Could this be the issue...bad connection? I would like to rule out all possibles before I get another compressor.
"You can test the compressor very quickly by hooking it direct to the battery and attaching a pressure gauge to the outlet port." Can you explain how I do this?
Leave it off. The purpose of the alegator clip is to be able to remove it quickly in case of a short. Here is a picture of your compressor.
If your compressor is making noise when turned on, it's working, if the wires are getting hot, there is excessive resistance in the circuit.
Here is how your leveling system works:
A Lincoln Town Car's air suspension uses a small, separate air compressor under the driver's side left fenderwell, and air lines run to the air bags. On top of each air bag is a electrical valve that serves as a relief valve that allows air to be exhausted when activated. The valve senses the amount of air pressure within the air bag to keep both sides equal. These valves are operated via a leveling sensor that is attached to the body of the car and to the rear axle by a movable arm. When the rear of the car drops because of an increased load, the arm is pushed up, turning on the air compressor and filling the air bags to level the car. When the load is removed and the arm moves down, indicating that the back of the car has risen, the sensor opens the valve on the air bags and allows air to escape, lowering the car.
I"m sending you a link that should help you with your problem. It is quite informative.
