1999 Lincoln towncar...something is contin. draining battery??
Tried it w/ two separate new batteries and new alternator. It drives until stopped, then dies. Power drains in idle position, and car needs a good jump everytime I stop car. Is it something electrical? Should I be looking for wiring diagrams?
Re: 1999 Lincoln towncar...something is contin. draining...
Have you tested the pigs tail at the alternator to see if you are get 14.4 volt from the alternator if not you have got a charging system problem as I have seen this alot in the UK the car loses the power from the ingniotion side of the start/charge system.
I you are still having problems let me now & I will try to make to a diagram for a stan alone system.

I can't imagine how changing the belt would have any effect on the electrical system if the alternator is working. The way you check for a drain is to disconnect the battery ground cable and use a test light to make the connection between the battery and ground. If there is something drawing power from the battery the light will glow. Then you pull each fuse from the fuse boxes until the light goes out. You also disconnect the starter and alternator if necessary.
I would check fuses and relays first..Check the voltage coming off the alternator on the big red wire,,instead of across the battery..Some cars still use a fusible link..You would no that if you have charging voltage at your alternator but not at the battery..Should be 14.0 volts or close to it..with no load
This has become a pretty common problem with the mid to late nineties lincolns. I had the same problem. What I found out from research and trial and error is your battery may be weak. So try replacing your battery. also try resetting your Inertia shut off switch located in the trunk on the drivers side front panel.
you have done everything right so far. now since what you have done didn't work. This could only mean that your Alternator is no longer working. The purpose of the alternator is to keep the battery charged up so all your car functions work. The alternator stands by to restore the electrical charge used to crank
the engine. It , once the engine is running, charges the battery and
runs the electrical system of the car. It typically takes about twenty
miles of driving to restore the charge to the battery from starting the
engine. Most alternators are internally regulated to assure proper
output voltage . Older cars have alternators with external regulators There are
some exceptions to this but this true in the majority of cases. One of
the exceptions is a high current alternator for a Lincoln that delivers
120 volts AC for receptacles (the same as at home) in addition to the
charging of the battery.
It sounds like your alternator is defective and draining the battery.
Since the alternators function is to charge the battery, if it's not working you will be running off battery power. With a short in the alternator that would explain the sudden drain on the battery.
BUT before you buy anything have the alternator tested first. It could be something more simple like a bare wire grounding out against metal, which would cause the problem.
Simple things first, so test it before you buy a new one. A parts store will test it for free.
Even still I suspect the alternator. A new will cost $160 maybe more.
Make sure the alternator is still connected to the battery. Should be a smaller wire running from the alternator to the positive post of the battery. There may also be a fuse for the alternator, check that.Your battery is not charging.
when you were driving, after replacing the battery, if u felt the car loosing some horse power, until it dies, then YES its your alternator, it is not recharjing the battery with power, so the car keep on sucking the battery until it dies, try to check your alternator, or check your the plug "located on the alternator itself"
