Question about 2000 Ford Expedition

3 Answers

Replaced battery and the terminal cables were put on wrong polarities; in-line fuse of positive battery cable blew as result. Replaced cable and reconnected to battery. Battery has full charge, but no power is going to any part of the vehicle i.e., dome light, headlights, hood light etc...., I have checked and no other fuses appear to be blown. Is there another reset switch somewhere that I don't know about?

You may have blown more than 1 fusible link. There are several Black powerboxes under the hood. Check if you have power going to these Powerboxes and go from there. It is difficult to check the relays but you can check whether they are getting the power to work.

Also, if you have good Insurance coverage you may be able to make a claim for this under Comprehensive. I had an A/C short out the wiring under my dash and Insurance covered it all. If this was done at a Shop, then their Liability should cover it.

One of your main electric wires comes from the Alternator. It is easy to get to, you could take it to Autozone or similar for a test. I would worry about the smaller items that would be damaged before a fuse would blow. This would include the onboard computer, stereo amplifier, Electric components in the transmission, and so forth.

I do not know of any reset buttons, but you can look in the Powerboxes and see if any relays have them.

Most likely that a fuseable link has blown, check wires that go to your starter for the link,,it will be hard[[the link]] when you find it. also,,,,did you check your fuse box under hood in black box? if not, you need to go there 1st. hope this helps!!

There are fusible link wires on feed to alternator & starter solenoid. Check for power to each right where they attach to respective units. If no power trace down wire usually within a foot of connector. If you have power there, you will need to cut out burned out fusible link wire & reattach a new section.

Blew a fuse installing radio. Now, van won't start???

Unfortunately some vehicles use the same fuse for ignition and non- critical electrical devices such as the cigarette lighter, interior lighting trunk opener solenoid etc... It could also be that the power supply wire (red) for the radio is double tapped to a fuse that is dedicated to any number of components and if it is interrupted (blown) the vehicle won't start or even crank. Another possibility is the vehicles computer detected a short or high amp draw and disabled the ignition to avoid fire or further electrical system damage.

The radio/player power line should be properly fuse protected for the highest amperage that the radio/player may draw when it is at maximum wattage, meaning CRANKED UP! It must be connected to the positive cable coming from the battery, safely away from the battery using a properly rated power terminal or power bar that is covered and sealed. It must be securely mounted, grounded and in an area that is clear of anything under the hood . This requires cutting the positive cable, putting connectors on each side of the cut cable and connecting them along with the player and power amplifier power line(s) to the new power terminal.

DO NOT CONNECT THE PLAYER LINE DIRECTLY TO THE BATTERY TERMINAL! The power line wiring for the player at max. volume MUST be of the correct amp rated gauge. You may also need to get a higher amp battery and a higher gauge battery cable to handle the power draw. It is also CRITICAL that every entertainment system component is SECURELY grounded with the right gauge ground wire to metal that is part of the vehicles frame. Failure to do this on a high amp system will toast your vehicles entire electrical system, (very costly mistake) also use dielectric grease on all electrical connections to maintain the integrity of all connections. I may have given you too much info, Good luck!

Replaced battery car will start but no power

try to disconnect the battery for about 20 minutes. hook it back up and make sure you have the positive and negative wires on the right terminal. wrong way can short and burn your entire electrical harness. Check the fuses.

Could be fusible Master link which is sometimes around battery and runs to fuse box. Looks like fat wire and melts connection from battery to body.

Another possibility is the wires to the Ignition switch. Most are inactive until the Ignition is turned on, but with reversed polarity things can happen.

Fusible Relays. You are lucky most of your truck is not computerized. But there may be an Ignition relay and a Light relay. Some had a grey module on the distributor.

Test for the fusible link first and see if it has melted. If you have power to the fuse box, check that there is power on the power side of the panel.

Replaced mega fuse now wont start

Putting reverse polarity to a battery will do more damage then blowing a fuse. Chances are you could have taken out the ECM and possibly the TCM

  3. Remove or disconnect the following:
    • The negative battery cable first, and then the positive cable
    • The hardware securing the battery to the tray
    • The battery cover, if so equipped
    • The battery from the tray
To Install:
  1. Position the battery on the tray and install the cover if equipped.
  2. Clean the battery terminals and cable ends with a wire brush.

You have short circuit between battery positive terminal and chassis.Follow a cable from battery to an alternator.If O.K. remove alternator and check all diods- 6 pse.Also check cable from battery to a starter motor.

  • Loosen the battery negative terminal clamp.


  • Use a terminal clamp puller to remove the negative cable.


  • Loosen the battery positive terminal clamp.


  • Use a terminal clamp puller to remove the positive clamp.


  • Remove the battery hold-down hardware and any heat shields.


  • Remove the battery from the tray.


  • Install the new battery into the tray.
  • Also install the hold-down hardware.


  • Install the positive battery cable.
  • Then install the negative cable.
  • When installing a battery, be careful to observe the correct polarity. Reversing the cables destroys the diodes. Proper polarity must also be observed when connecting a booster battery, positive to positive and negative to ground.

  • Coat the terminals with corrosion preventative spray, then check the job by starting the car.

Possible electrical problems.

I would suggest that you check to see if the battery is connected properly---correct polarity!

If connected wrong, main fuse will blow. Lights come on because power is routed through the frame (ground) briefly.
Hope this helps.

Volvo 850 is dead after wrong polarity at charging

It is possible that you have melted a fuseable link. These are heavy guaged wires coming off the positive battery cable. Their purpose is to protect the electric system in the event of such a case.

If you would like to correspond further with me on this or any other issue, please feel free to do so.
