CTEK Porsche Battery Charger ?

Hello again, I posted this question a week ago, but need to be sure I am not an idiot. So I bought a CTEK Porsche charger, which I have used before on my other Porsches , but never with this issue. Once the battery says it is fully charged and fully green on the right side, the light above the motorcycle keeps flashing very fast. So I thought I had a defective charger and returned this one for a new one and exactly the same thing. I am almost positive ,I never remember that middle orange light flashing quickly once fully charged. Is this normal because I cannot buy another one, so maybe someone can explain. Sorry to sound stupid, but just trying to figure it out(used both sockets too). Thank you in advance for the people patient enough to deal with such a dumb question!

There are numerous threads on this issue, so put your flame suit on. Bottom line is that if the outlet you're using goes to sleep, either its not hot wired or it times out before you plug in the charger, you wont have a complete circuit and you'll get the flashing yellow light as you have described. Try this:
Unplug the charger.
Start the car - just run for a minute and shut it off.
Immediately plug the charger into your preferred charging port. Start with the one in the passenger foot well.
Immediately plug the charger into the wall outlet and select your charging mode.
If after 15 minutes there's no flashing yellow light, you're good to go. If you get the flashing yellow light, start over but this time select another charging port.
If all else fails, hard-wiring to the battery appears to be a fail-safe alternative to the in-car method.
Good luck.

Thanks Dave, but the light that flashes is Orange not Yellow. Also my outlet seems to work perfectly because it charges my battery, but once fully charged is when the Orange light right above the motorcycle starts flashing quickly.

DK, I had the same problem with my 7yr Porsche tender as well. Though it was a bad fuse,changed it still had same symptoms you had. Bought new Porsche Tender. All good.

I use a CTEK 4.3 on my 2015 991.1 C2S in the cigarette lighter, with CTEK set to the "snowflake" mode for my AGM battery, and have never had a problem on this Porsche, or on my previous 981 Cayman S and Macan Turbo. My CTEK is about 3 years old.

Woodranch - aren’t you located in Orange County? I have a spare C-Tek charger if you want to try swapping to determine whether it’s your car or the charger. PM me.

Can anyone give me the campaign number to stop the cigarette lighter ports from shutting down after 10 minutes once the car is turned off. I think that really is the problem! Mine is a 2016 and I read that they started doing that in this year. Not sure if that is true but seems logical. Looking my doors does not solve this issue either. Thanks again!

In my experience, the lighter port will stay active if there is activity on the port BEFORE it shuts down. Did you follow my suggestion above to test it?
