488 Newbie - 488 battery tender challenges

Hi all - I'm new to this community having bought my 488 about a month ago.

It came with the Ferrari branded battery tender, but the connection to the port on the rear bumper was partly broken so I bought a JMR connector to connect my CTEK 5.0 battery tender to the rear bumper port.

Unfortunately, neither battery tenders seem to work. The lights on the bumper port connector don't light up to show a connection to the battery (first photo) and the CTEK only shows the green light for a couple of mins then turns off with none of the battery conditioning lights lighting up (second photo).

I'm wondering if it's an issue with the port or the fuse for that port. Would love to hear from others that may have had a similar issue before I take it into to be looked at...

Thanks

Thanks both. I had already tried cleaning the connection with rubbing alcohol and adjusting the position of the connector but no joy.

Got a multimeter out and nothing at all.... the Ferrari battery tender that came with the car had a wobbly wire to the connector, so I'm now wondering if that caused the problem.

Any idea if replacing the magnetic charging port is a DIY job or do I need to take it in? I'm ok tinkering with my cars but this is new for me. Reading around it looks like Magcode makes these for Ferrari and they seem to be available.

Great will give that a go. I wasn't sure if I'd just pull or unscrew. Will give that a go when I have some time over the next few days to check the wires and the inline fuse, and will let you know. Thank you!

 

haha. I did think that was a bit of a dramatic suggestion for a failed battery tender port

Will look to unscrew it and check it this evening
