Question about 1998 Ford Expedition

Battery on 98 Ford Expedition doesn't hold charge

My battery on 98 Ford Expedition doesn't hold charge, I've switched the battery out 2 times already & the alternator tested good. My running board lights & interior lights come on & off constantly so I have to pull the fuse. I removed my stock premium sound cassette stereo and replaced it with an after market car stereo. I have no sound from stock speakers so I have 2 other speakers hooked up to the after market stereo!!! If I arm my after market theft alarm and open any doors, lift gate, or back glass the alarm system does not come on. I am SO IRRITATED with this vehicle!! If it's not one thing it's another!!!

    I disconnected after market car alarm which I have had for 7 or 8 years and battery was still draining. I dont know if the stock key less entry was disconnected at that time. I found the switch in the back lift glass was worn out. A friend adjusted the switch and the interior lights, running board lights, & door ajar notification now stays off. NOW my starter went out!! I tell you if it's not one thing its another!!

First thing I would do is have someone qualified disconnect the alarm and stereo and start over.
Chances are you have circuits cross-connected and something is draining the battery.

SOURCE: 03 ford expedition interior lights stay on and door ajar reads

This is a very common problem with Fords. I have one that was doing this as well. What works for most people is pretty much what you have tried - spraying inside the latch all over with WD40 Until it's coming out the bottom of the door. If this fails to work, the switch probably needs replaced. The switch is located inside the door near the latch. It should be pretty easy to find once you have the door panel off. Look for the wires leading to it. A new switch is usually very inexpensive, but may have to be purchased through your local Ford dealer. If you're not comfortable taking the door panel off, a mechanic should be able to do this repair for you in less than an hour of shop time.

I have a 98 expedition I changed the alternator and battery but it still won't hold a charge


The alternator fuse is probably blown. You have an hundred amp fuse above the battery on the firewall. Check it.

I've been having a problem with my 2000


No.dont diconnect the negative or positive battery at all The alternator only produces 2 volts above battery voltage so a total of 14 volts. If you dont have a volt meter get a small screw driver be careful doing this if you can safely access the back of the alternator (without shorting anything out)in the midddle of the alternator will be magnetic. That will tell you its charging or better yet get a compass and put it at the battery positive terminal and it will swing that tell you its charging. You disconnect the negative the whole car shuts off you disconnect the positive the car stay running but produces high voltage and can damage the alternator itself

I have a 97 Ford Expedition. Every time I go to crank up it won't crank I would have to get a jump. And I'd just bought that battery a couple of months ago. Then when I took it to be checked out I...


ok, first, once the vehicle is started, the alternator should take over the functions of the car,, not the battery , the battery should charge during this time, ( car running) if the alternator is having to supply to much juice to the battery the whole car suffers, and the battery never fully charges . Just because the battery says 12 volts, doesn't mean the amps are there, which you need to start the vehicle,, take the battery and get it LOAD tested, this will let you know if one or more cells in the battery aren't up to par, if it doesn't measure up,, get it replaced, you sate that its only 4 months old, so take it to someone other than who you bought the battery from, and have it load tested there, once you have a known GOOD battery ,, start the vehicle,, then with a meter check the battery posts,, you should get a reading of between 13.5-14.5 volts, if you don't,, your alternator isn't doing its job and will need replacing

probably one or both or your batteries are low or shot, check both of them. Hope this helps-Jim If water in them is low, refill with distilled water, and then charge them. If it still doesn't start, you may need a replacement.
