Im havening trouble with 1996 Jaguar XJ6 (VDP). The Car is having trouble starting every other time. I go to turn the key and I here a Click from my starter and the engine doesnt Turn over. Just makes that clicking noise. I turn it a second time and it starts right up. It seems every other time starting the car it just makes a click from the starter. Does anyone have any Ideas what could cause this?

1) I put a new starter
2) had the battery check 3 times and it is good.

Still does this every other time or so.
