the alternator on ,y ep3 race car failed recently. Bearing failure which led to the alternator case cracking - it was running but really noisy and no alternator light. I’ve fitted a new alternator and the red dash warning light is now on. Must be a faulty new alternator - so I’ve swapped in another new one and still have the alternator light on. It’s pushing out 14 v when running so charging. Any ideas?. (I hate electrics)
