Can this product be repaired?

The "F04" code on a Vector battery jump box typically indicates a fault or error within the unit or its connections. This error could be caused by a poor connection, a damaged battery clamp, or an issue with the box itself. To help fix the issue, try these steps:

1. Ensure the battery clamps are clean and not damaged.
2. Check the connections between the jump box and the battery terminals. Ensure the positive (+) clamp is connected to the positive terminal and the negative (-) clamp is connected to the negative terminal or a suitable ground location on the vehicle.
3. If possible, test the jump box on another vehicle to confirm it is working correctly.
4. If the issue still remains, consult the user manual or contact the manufacturer for further assistance or information on potential repair options.

When Connecting jump leads ALWAYS Positive first, (Red), Negative last, (Black).
When Removing jump leads ALWAYS Negative first, (Black) and Positive last, (Red).
ALWAYS make sure you DON'T touch the negative to the positive at any time! (Loads of sparks and you risk damaging the battery).
Safest way I have found is this.
With the engine on BOTH vehicles turned OFF. Connect up to the flat battery first, then connect to the good battery. ONLY start the vehicle with the good battery. Wait 2 or 3 minutes to let some charge cross to the dead battery then start the vehicle with the dead battery.
The dead battery will need to be fully charged as soon as possible.

Good clamps are available from NAPA, Autozone, O'Reilly's, Pep Boys, Car Quest, and other suppliers. Check to see if the existing wire terminates in a crimped lug. If not you need to look at the new clamps to see whether they are designed for attaching directly to the wire strands or if they require the wires to be gathered and crimped into a lug to go under a single screw. Fasteners to clamp large wire under a screw are similar to photo here.

Sure, you can find it on amazon... here: Amazon com Husky jump start adapter . I hope I have helped. Cheers

If you cut them both then you'll have to open it to see which one goes ti the battery + and -

Dead battery. Try jump starting it. Then stop by any good parts store (Advance, Autozone, etc) and have them to a FREE charging system test and a FREE battery load test. I suspect your battery has left this planet...

on the good car, clamp onto the positive post then clamp onto the dead positive post on the other vehicle.(making sure that both vehicles dont touch each other).Then clamp the black negative on the good vehicle and then clamp the black negative lead on the dead battery to a good engine piece of metal or large bolt. Start the good car and let it idle for five minutes. After this make sure that the only light on in the dead car will be the interior light, shut off all other electrical devices, radio, wipers,headlights "if possible" then have the person in the good car rev the idle up to about 2000 rpm and hold it there while you try to start, if it wont start after 10 seconds, find a better ground, wait a few minutes again before trying. if it doesnt start you may have a bad cell take a voltmeter and measure between the two post on the dead battery..if its lower than 12.3 volts eg, 11.7 its bad....batteries usually only last three years!
any feedback would be appreciated.
thanks

First of all I don't recall any additional wiring or a junction box being attached to the negative battery terminal of a Ford Escort. I do however remember these things being fixed to the positive terminal...

The first thing that should happen is your battery should be removed from the car and fully charged and tested and replaced if necessary. I suggest you note; in the case of a completely discharged battery it is possible to inadvertantly connect the battery charger wrongly and charge the battery back-to-front or so the polarity is reversed.

Once there is a known good battery fitted to the car the correct way around and with any bad connections to or near the battery repaired it will be possible to begin the process of diagnosing the original problem(s).
A car that started with a jump start should now start from the key and the charging system can be tested and repaired if found defective..

I suggest you entrust the work to an experienced person...

You can either jump the battery, or remove the battery from the car and bring it to your local repair shop to have it charged and tested, (a lot of auto supply stores will do this for free so call around), or you can jump start your battery and hope it holds a charge.

To jump a battery you will need a set of jumper cables and a second car, or a battery booster pack, (nice investment, they really are handy in a jam).

To jump a car with jumper cables:
******* Always where eye protection*********
1) Open the hood on the dead car and locate the battery.
2) Park the second car as close to the front of the dead car as possible, (just try to leave enough room to walk around the vehicles if you can).
3) Open the hood on the second car and locate the battery.
4) Attach the red, (positive) cable clamp to the Positive, (+) terminal of the battery on both cars.
5) Connect the black, (negative) cable clamp to the negative, (-) terminal of the battery of both vehicles.
6) With the second car running leave the vehicle to sit for about 5 minutes then attempt to start the dead vehicle.
7) If vehicle fails to start, wiggle the cable clamps to create a better connection.
8) If vehicle starts, remove the cable clamps negative first then the positive.
9) You may consider bringing the vehicle to your local auto supply to have the battery load tested once the car has run for a while, (most auto supply stores will do this for free so call around)


Using a booster pack is basically the same, except, you replace the second car with the booster pack. Follow the manufacturer’s instructions for charging the booster pack before use.

Good luck. Please rate, thanks.

Possible dead cell in battery, most likely a fault in the charging system. First, Jump Vehicle to get started then remove the Negative cable. If the vehicle dies when you take the jumper cables away or when you disconnect the negative cable your alternator or charging system is faulty. If the vehicle runs without battery connected you have a bad cell in your battery, replace the battery.
