Cen tech a JNC950 2000 Peak Amp 12 wont take a charge

An EF-02 flashing error on the Cen-Tech 63873 battery charger means that there is a short circuit.

I don't have the same jump box but I have ran into the same problem is either gets charged in the garage or in the house that's best result for me anyway

Google for an owner's manual. I can't find anything on this jump starter, but first they need to be charged, usually by plugging into a wall socket for 12-24 hours. Then plug into the cigarette lighter for 10 min or so to give the car battery a boost charge.

Just as your information says ask for a 12 volt 700 ma charger..but seeing that yours is a 450 amp jumper..any 12 volt that fits your ac input will do the job...one more thing if you do not have a charger..just connect it to your battery and run the engine for 20 min or so it will recharge the car battery and you jumper..also you can get a lighter wire with two lighter plugs and charge it through you lighter..good luck

All OBD Codes are on the internet with

I had to Google Cen Tech as i never heard of it

They appear to be inexpensive low end for sure

You won't get a lot of data out it

If your never planning on going to professional software,
consider the top scan/code reader type tools like Innova Professional or at least mid level Actron & a couple other brands

You really need to see sensors,emission monitors, so
your ready for inspection

You will only get Generic Codes from a code reader
not body functions likes abs,air conditioning,srs,& others

More data is better-- you will learn these systems as time goes by

They have been with us for 35 years now

Sorry to say, but Harbor Freight's parts list has no internal parts listed. So to fix it yourself, you may be able to find the little tiny diodes that usually go bad. They don't even have a wiring diagram in the owners manual.

I don't think so, It did that on one of my lawn tractor batteries but not on the other lawn tractor or car battery, I suspect something is wrong with the battery.

Wow. That was no help...we post to find links without having to leave the home or the project at hand....

RMS(power) = peak(power) * .707

find the peak power of your amp and use the above formula

It will have enough power to do so.
