Good afternoon, learned members.
I’ve just started my FF for the first time in three weeks.
It was sluggish on the starter, but turned over well enough to start it. I let it run until it was warm, with the temperature gauge half scale deflection.
I then shut it down for two minutes while I looked for leaks (fortunately leak free).
When trying to restart it after that two minute wait to ride it back into the garage, it wouldn’t turn over at all, with all the symptoms of a dead battery, except that when I tried all of the electrical demands they were fine.
It’s a new battery fitted five months ago (though not been charged by an external charger since installation).
Is this non - cranking when it was warm just a flatish battery, or something more sinister to do with the engine being warm? I would have thought that idling it for half an hour with all electrical services except the ignition and fuel pump switched off should have replenished the battery sufficiently that a restart wouldn’t be a problem.
Edit: After waiting an hour, the engine turned over easily on the starter, and it started first push.
So is there something getting tight when the engine’s warmed up?
