I'm charging my battery on my rv new. Artery but it was ran down because my break switch was bad and the light stayed on my new cen-tech charger light stays green and I hear a clicking

Disconnect any wiring to the battery. Connect only the charger. Insure you have the charger connected to the proper polarity.

Does it continue to click? Does it not charge? If it won't charge for you, pull the battery and take it to a friendly service station or auto parts store that can test, and or charge it for you. It could be you discharged the battery all the way and damaged it. The normal safe zone is to never discharge below 50%. They might have to attempt a charge that takes up to 45 minutes. If the battery is over a couple years old I would opt to just replace it. I would never trust it and end up getting stranded somewhere.

Cen tech code reader problems 98568

All OBD Codes are on the internet with

You Type your codes & read up

Study OBD 2 Systems also


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

OBD1 15 years
OBD2 20 years

I need battery charger cen-tech 69368 manual

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.

Cen-Tech code P0113 intake air temperature sensor 1 circuit high.

Check intake air boot or duct for a small 2 wire sensor, you may have not seen it as u pulled duct out of your way, don't feel bad I've done it before check that first , if u can't find one that it will be a internal part of the m,a,f, mass air flow sensor , usually a big round sensor inline of intake duct both of these will be before the throttle body ,mag has 4-6 wire connector !

probably your battery cant conform minimum requirements of digital circuits used to drive starter motor in high tech cars. that is why it works only with external charger. measure your abttery. it should be showing at least 12.4 volts. normally battery should show 12.5. to 12.65 volts. probably your battery has sulfation. end of its life.
