Ford Wiring/Electrical :: Battery Won't Take A Full Charge

I have a vehicle I am storing for the winter, but do want to start it up on occasion just to keep it fresh. my question is this. I put a trickle charger on the battery to keep it charged up, its one of those chargers you can leave on indefinitely, once the green light goes on the charger, it goes into maintanance mode. but I've had the charger on for a week now and it seems the battery won't take a full charge. to put the battery charger into maintance mode. is it dangerous to keep charging a battery that won't fully charge up?

Ford Wiring/Electrical :: 1999 F150 - Battery Light Came On

I have a 1999 Ford F150 6 cyl. 4.2, 2 WD with 160,000 miles. Replaced the battery May 2010.

Today battery light came on. Battery gauge did not look like it was discharging. Had battery checked they said it was a little low but OK. Then they continued test and tried to check alternator, test stopped and they said something wrong with alternator most likely.

I took alternator out and had it bench tested. They said it was OK, putting out 98 amp on 95 amp alternator. They said check wires, grounds, harness, connections. Checked connections and wires as much as possible, reinstalled alternator, light still on.

Have not checked fuses yet. Was told to start vehicle, disconnect positive battery cable and if engine continued to run alternator was good, if cut off alternator was bad and to replace. Should I try this and is it true?

What is the part on the fire wall that is between the alternator and the battery that the wire connection runs through? Can it be bench tested/checked?

Ford Wiring/Electrical :: 1998 F150 - Truck Won't Start With A Fully Charged Battery

I have a 1998 Ford F-150. It has an issue with starting sometimes. The truck won't start with a fully charged battery but when I hook it up to a charger, the truck starts normally. It was going to get the wheels aligned today and when the mechanic went to drive it off the ramp, it wouldn't start. I told him to put a charger on the battery and it started right up. Without the charger it just cranked over and wouldn't start. It doesn't do this every time I go to start it only occasionally. The mechanic had no idea what the problem was and has never heard of this kind of situation. I'm assuming it is an electrical problem but I'm not an expert with engines. The battery was fully charged at the shop and the battery is a year old.

Ford Wiring/Electrical :: 2006 F150 - Battery Light On / Voltmeter Spikes / Grinding Noise As 4x4 Engages

Problem with my 2006 F150 5.4 4x4... Voltmeter spikes, battery light comes on, grinding noise as 4x4 engages on its own then everything returns to normal after about 60 seconds. Took to Ford who replaced the alternator and battery, still doing it so they replaced the alternator again...they checked the wiring and replaced some other misc parts and don't know what the problem is. The problem occurs once every few days, after only a few minutes or after a few hours, completely random.

Ford Wiring/Electrical :: 2008 F150 - Cold No Crank / No Start

I have an 08 F150 5.4L with about 68k miles. When the temperature is 40 degrees or colder it will not crank. I had the same issue with my 2005. I can turn the key and nothing, lights, radio and everything work. The dash display has dashes all the across for the miles, temp and compass. I have found out that it doesn't matter if I leave the key forward in the run position or try to crank, it won't do anything.

Battery is good and no problems with the truck. After the key is in and I give it anywhere from 15 to 60 seconds you can hear an electrical click real faintly and see the red security light come on and then the computer display comes on and then I can start with no problem? What could this be? My dealership has no clues and I can get it to act up because after I get it there it starts with no issue. The remotes work fine and this issue was why I got rid of my '05.

Ford Wiring/Electrical :: 2000 F150 - Power Cuts Out When Attempting To Start

2000 XLT F150 4.6 - New starter & solenoid(s), battery cable & fuse links good.

When i turn the key, I hear one single click and the power cuts out entirely. I can't attempt a second start or turn on the lights or have any power going through the truck until I disconnect the battery for about 10 seconds then reconnect. Electrical becomes live again, then when the ignition is turned the electrical cuts out again. I do hear a single cluck at the starter (probably attempting to engage when it cuts out) and a clunk right at the inside fuse box (drivers side).

Ford Wiring/Electrical :: 1994 F150 - 12V Signal To Indicate Engine Is In Start And Run Mode?

I have a need for a 12-volt signal to indicate the engine is in start or run mode. I would like to pull this from the engine compartment but I'm not sure what would be the best or easiest way to do this. The 12-volt signal is not used to power anything so it will draw very little current. I have a 94 F150.

Ford Wiring/Electrical :: 2000 F150 - Hooking Power Door Lock To Command Start?

I am trying to hook up my power door locks to my command start. I am having trouble getting it to work. Ive tried a number of relay diagrams from the12volt.com. I've tried actuators/reverse polarity and it blows both my factory door lock fuse and the fuse I have supplied to the relays. Ive also tried 5 wire alternating 12 volt positive door locks, and 3 wire positive door lock combinations. Both of these combinations the relays click back and forth fine with the actuators unhooked, when I connect the actuators the doors unlock with the factory switch but when I unlock with my remote it blows the fuse. How to properly connect the actuators?

Ford Wiring/Electrical :: 1999 F150 - Fuel Gauge Indicates Empty At All Times

My fuel gauge indicates empty at all times. The first suggestion I received was to replace the sending unit in the gas tank. I did that but the gauge still indicates empty.

I tried the HEC Dealer test mode and I now know that FUEL reads 255. Which should be an 'open' state. The connector near the fuel tank does appear to be making good contact, so my suspicion is a broken wire somewhere between the rear of the truck and the front.

I tried following the wire on it's way towards the front of the truck, but I quickly loose sight of the wire as more branches enter into the wiring harness. Where does this wire end? Does it terminate in the engine compartment, at the instrument cluster, somewhere else?

I just can't figure out how to narrow down where the break in the wire might be. Or am I chasing down the wrong root cause?

Ford Wiring/Electrical :: 1987 F150 - Wiring Diagram With Carburetor?

Looking for a wiring diagram for a F-150 XLT LARIAT 5.8L 4BBL, all the books I have looked at show the wiring for this year with fuel injection and this truck came with a 351W with a Holley 600 4BBL, I have a few wire's in the engine compartment that melted away all the insulation, they are located close to where the harness passes the firewall before the ignition module. Is this a common problem on old models ?. Need a clear copy of the correct diagram for a f-150 1987 with carburetor, how I can get a copy so I can fix this problem before it gets worse.

Ford Wiring/Electrical :: 2002 F350 V10 Won't Start / Cranks Slowly Like Battery Is Dead

I have a 02 f350 v10 with a starting problem. Sometimes it will crank but really slowly almost like the battery is dead, but its not! bench tested the battery and actually just bought another new one. And with the same result. I tested the relay that's on the firewall in between the starter and the battery and it checked out, i also bought a new relay and i want to put it in except I haven't figured out which wire goes to the coil and which one goes to the ignition. the battery and starter poles are marked and easy to follow ..

Also last month I changed the starter but I'm starting to get desperate and i think I'm going to take it off and have it bench tested as well. I'm just really at a loss in which direction to go. The truck on the outside really looks good but living in the northeast the frame and probably most of the outside grounds are toast and I've been renewing or just placing them as I come across them. Before i forget i tried jumping the starter directly from the battery with cables and got the same result. it would crank but too slow to actually turn over.. Sometimes my radio and ignition lights will sometimes come on without the key in the ignition..

Electrical-wiring - Ranger :: 1999 XLT Electrical Power Lost When Turn Key To Start Position

My 1999 Ford Ranger XLT, 6 cylinder, auto trans, with 134K miles has an electric problem. When I turn the key to the 'on' position, all dash lights show normal, headlights work, radio plays, etc. But when I turn the key to the 'start' position, all electric power is lost. The power remains lost until I disconnect and reconnect the battery ground wire. After reconnecting, I again have power until the key is turned to the 'start' position. I was able to jump start the truck, so I assumed I needed a new battery. I bought one a week ago, and was back to normal until today. The truck started, I drove 4 miles to the grocery store, and then I found myself back to square 1 (i.e., the no-start situation).

Ford Wiring/Electrical :: 1995 F150 - Headlights Not Turning On

Here's the breakdown. I have a '95 Ford F150 that I bought the previous year and it has been nothing but a problem. The most recent problem is the attempt to turn on the headlights. I will pull the plunger to turn on the headlights but I will only get the parking lights and when attempting to turn on the high beams I still get nothing. The only way that I get any sort of lighting is if I pull on the turning stick (almost like doing a manual override on a tripped wall plugin). Now here's the kicker. I still have parking lights, brake, tail, cab, and dash lights. Winter in quickly approaching and the nights are already getting dark, pretty soon the days will be just as dark.
