The 1998 and upward Town Cars take electronic systems that monitor any activity (unlocking or opening doors, opening hood, opening trunk, etc) that may point the imminent operation of the auto. These systems swallow small amounts of power (all the time) of about 40 miliamps for 1997 and before models and up to fifty miliamps for 1998 thru 2002 models and upwardly to 80 miliamps for 2003 and up models. A healthy battery will sustain this bleed for weeks and still allow the vehicle to start. When the monitoring organisation detects an activity it immediately wakes all the systems (and the battery bleed spikes large time) prepare for a startup. If the startup does not come in about forty to threescore minutes the systems go back to sleep and leave the monitor ready to react next fourth dimension. However, a failed diode in the alternator or an electric fault in the car's electrical system may cause a bombardment bleed overnight or just a few days and prevent the car from starting.

The 1998 and up Town Cars have electronic systems that monitor whatsoever action (unlocking or opening doors, opening hood, opening body, etc) that may signal the imminent operation of the car. These systems consume small amounts of ability (all the time) of about 40 miliamps for 1997 and earlier models and upwards to 50 miliamps for 1998 thru 2002 models and upward to 80 miliamps for 2003 and up models. A healthy bombardment will sustain this drain for weeks and still allow the vehicle to starting time. When the monitoring organization detects an activeness it immediately wakes all the systems (and the battery bleed spikes big time) set up for a startup. If the startup does not come up in about forty to sixty minutes the systems become back to sleep and get out the monitor prepare to react adjacent fourth dimension. However, a failed diode in the alternator or an electric fault in the car's electrical system may cause a battery drain overnight or just a few days and prevent the auto from starting.

I have a 97 town car, would these tips & process employ ? I noted the 98 & up years.

Hey Folks, im a High german Guy who stay at Austin till next Summer and i bought a 1999 TownCar. And this (maybe) drains the Bombardment to... only not like described here in i or ii weeks but in round well-nigh one Calendar month. Could that be?? Or is at that place may another Problem?? Usually i drive every weekday simply six Miles to my Work (3 miles one Style)... so its maybe only a small drain and i have information technology because i only drive not a long enough every day to charge that. I likewise was at a Mechanic and he said the Alternator is okay...

Whatever Ideas??

Welcome.

A member here with a 2007 model went on vacation and left his battery connected and the machine in normal working condition. When he returned in 32 days the bombardment was completely dead. Your car, if in perfect condition, will accept a continuous battery drain of around 50 milliamps and that will spike above that level. So it will bleed in fourth dimension. Only how long depends on the state of the bombardment and how well charged when left to sit down. Batteries don't like sitting uncharged, they sulfate and lose their ability to retain a charge.

So I think your organisation is working as ane would expect, information technology is being tuckered regularly and non charged fully. And then you lot need a bombardment charger to meridian up the battery regularly. A regular battery charger would have to be monitored to ensure information technology does not overcharge, even at the low charge rate. You can get battery chargers that monitor the battery charge and give it merely equally much as it needs, and some can be plugged into the cigarette lighter. This battery meridian upwardly will eliminate the sulfate build upward and therefore finish information technology from hardening and rendering your battery useless. Some of the more expensive ones will pulse the electric current and voltage to break up the sulfate eolith on the plates and restore battery power and reserve capacity.

Good luck, and enjoy your stay in the US.

Cheers for that long Respond. If i've u right sympathize the Battery Drain is a normal thing at a TownCar?? in Otherwise if i drive more the six Miles / Solar day information technology would accuse the Battery and i did not have the Problem? I have a make New Battery i change the Last i at Walmart because it was also merely one Month onetime and i idea the Battery is damaged. But Ane Week ago i had the aforementioned Problem... the Bombardment was empty... but i could commencement The Machine once and i drove again to Walmart to change information technology :) i know its bad and non the Solution but information technology works for now because i want to accept a Road Trip from Austin to New Orleans. Normally the Bombardment should work for that two weeks... hopefully!!! I likewise buy at Walmart a portable Power Spring Starter in the Hope if i had the same problem in the next 2 weeks i tin can help my self with that thing.

U said i need a "Battery charger"... but u mean a thing where i connect the Bombardment with a regular power supply organization? But the Problem: i've no Garage ... that means i accept to remove the bombardment from the car...bring it to my appt. and charge information technology in that location?? thats really not pretty handy.. :-(
can the other way be to find the "Drainer" or is it just regular the drain?

Hi Howard,

You empathise the problem. Y'all cannot cease the drain except by disconnecting the neg terminal on the battery, and that means the PCM relearning the idle and trans shift schedule and you resetting the radio and EATC controls. Since you cannot conveniently charge the battery with a charger then merely take the car for a longer drive occasionally. Your automobile's alternator will charge the bombardment quickly. Good luck.

Take care,
Art

Town, I'yard new to the site: 2001 Connie. I don't see a forum for me simply Town Car might serve. I use only my iPhone but am unable to open up any of the attachments you oftentimes include. Thanks for all your inputs and advice.

Welcome bailsout,

The tech articles for the Continental are in the Tech department, mixed in with the LS and other general manufactures. I accept asked for the LS and Continental to have their own dissever tech forums only similar the Boondocks Car and Zephyr/MKZ merely it probably takes a while to do that.

I used to post attachments every bit Word files, but recognized that some do not accept Word software so I usually mail pdf formatted files which accept a common reader called "Adobe Reader". It is available at no charge from the Adobe site. I have no experience with the iPhone but I would imagine there is a reader or an App that volition allow yous to admission pdf files.

My son has an iPhone 5 so I will inquire him how he accesses pdf files.

Skilful luck.

Hi bailsout,

My son can read pdf files on his iPhone. He says to download adobe reader for gratuitous from the App Shop. That should ready you up just fine.

Annihilation else you are having trouble with, related to this site of form?

Proficient luck.

Yesterday I collection the TC after v days of decay. The steering was very heavy and the electrics didnt work properly. I diagnosed the steering as not plenty air in the tires because a week ago the dealer did a periodic check and let the air out of my tires to but 32psi. I had them set at 40psi. I didnt observe the heavy steering when I brought it home, but I increased the force per unit area to forty and this morning it was dorsum to normal. But later the symptoms I had this morning, I am not sure the air was the problem.

Afterward church this forenoon the car would non turn over then I had to have it jumped. On the way dwelling house I discovered that the interior calorie-free switch had been left in the full on position and that all the interior lights were on and had been on for at least 24 hours (I was working on the new GPS arrangement yesterday). I think that was what tuckered the battery.

But at present I am wondering if the battery existence depression could have somehow afflicted the tuning of the ability steering??

You say a "fasten" whern the car is in standby mode. Would 1.5 Amps be reasonable when in standby mode?

Hi jimisbell,

No non i.five amps. The fasten would be from lxxx milliamps to 140 milliamps.

Good luck.

Yesterday I collection the TC later 5 days of disuse. The steering was very heavy and the electrics didnt work properly. I diagnosed the steering every bit not plenty air in the tires because a calendar week ago the dealer did a periodic check and permit the air out of my tires to just 32psi. I had them fix at 40psi. I didnt observe the heavy steering when I brought it habitation, but I increased the pressure to 40 and this forenoon it was back to normal. But later on the symptoms I had this morning, I am not sure the air was the problem.

Afterwards church building this morning the car would non turn over so I had to have it jumped. On the way domicile I discovered that the interior light switch had been left in the total on position and that all the interior lights were on and had been on for at least 24 hours (I was working on the new GPS system yesterday). I recollect that was what drained the bombardment.

But now I am wondering if the battery existence low could have somehow affected the tuning of the power steering??

Hi jimisbell,

The electronics are definitely affected by an unstable electrical system, but ask zinctwentyone about his battery and alternator issues affecting his air suspension and other components. From your other mail service I presume you accept a continuous drain of 1.5 amp on the battery with everything off including the interior lights. I would have thought the battery saver feature would take switched off the interior lights after 20 mins or so just I never checked that. The lights would switch dorsum on when you opened the door so yous may have some other drain. Any drain would be significant since you don't have much more 60 amps available from a charged battery anyhow before its flat (reserve chapters of stock Motorcraft 750 battery is 140 mins at 25 amp-hours load is about 57 amps and still just outset the motorcar.

Depending on your length of trip to church your alternator sounds a bit suspect as well but you tin can get it tested forth with the battery. A failed diode in the alternator will discharge the battery chop-chop at a rate usually well above one.5 amps.

My tire force per unit area is 32 psi all around (down from 32 front 35 rear since hearing that later on models accept 32 front and rear) and the steering has lots of ability at parking speed.

Skilful luck.

Turns out its 2.five amps. But I see no mode to measure the quiescent number because to mensurate it yous have to open the hood which will actuate the standby fashion. Its a Grab 22

From your comments it would seem to be that I accept a real problem. I recollect that my installation of the new Audio, GPS may have a wiring mistake. It is wired with a "keep alive" function and so that the presets are not lost when the key is turned off. But I must have made a mistake.

Off comes the dash trim again....LOL

Hullo jimisbell,

Yes you tin mensurate the value. The system lights up when you open the hood and connect your multi-meter between the neg battery cablevision and the neg battery post. But afterwards a menstruation of time the system goes to sleep and you have the 80 milleamps (that occasionally spikes to 140 milliamps) plus the 2.5 amp unwanted describe (two.58 amps spiking to 2.64 amps if there is no other depict). So at that point your access to the circuits should be articulate so no opening of doors, etc. Just deal with the "audio" circuits to detect your trouble and correct information technology.

Proficient luck.

Well, it seems the audio system is Not the problem. It is wired correctly.

When I pulled the dash trim I noticed that the parking light switch was ON. Merely I went on testing all the connections including if the drain dropped when I turned the Audio on and off and unplugged it.

What I establish was that with the audio unplugged the quiescent drain is 450 milliamps (0.450 amps). With the audio continued in standby way the drain goes to 600 milliamps (0.600 amps). Thats an increase of 150 milliamps. The Clock draws Nix measurable. The parking lights draw 1.v amps.

That quiescent current is three times what you are suggesting, Boondocks. But I dont have a trouble with that because the bombardment can easily handle that for a week or more than. Thats only a 7 watt load.

Apparently when I removed the nuance trim to install the audio organization earlier in the calendar week I bumped the switch into the parking lite position. Only what I dont understand is how I would Non have seen the lights when I went out last dark and the nighttime earlier to work on it. It was so dark I had to utilise a flashlight to observe the car!!! Merely I could not run into the parking lights were on ? ? ? I dont believe that.
