My F-type has been experiencing some intermittent power to the stereo and most recently with the headlights. The stereo interrupts for a second and the head lights flicker about every 5-10 minutes. This happens on smooth driving surfaces. Sometimes the interior light selection also changes from blue to red during these flickers.
Has anyone else experienced this? I am going to examine and replace fuses, clean all the connectors I can find and look for ground shorts. Does anyone have any other suggestions?

I guess I would start with the battery connections and state of charge

Can anyone recommend a high quality battery replacement for both? Thx

I have been trying to identify a battery available in the USA. It seems you can only get a replacement from the dealer. In Europe you can buy FIAMM but not available in US. So far unable to identify a true US replacement AGM that fits.

I had the battery tested before buying new one and it was good. After the test I started pulling on the primary power cables and found the ground wire wasn't tightly secured to the battery pole at all. Dealer probably forgot to tighten after servicing. Tightened it and all good, probably saved me a $500+ dealer visit...
