Hi. My coupe has developed a intermittent charging fault. When the car gets warm the alternator stops charging. The revs also dip randomly. I have had the alternator tested at an auto electrical centre off the car whilst cold and he said it is in excellent condition. But when i put it back on again when warm it did it again. Has anybody come across this before or ever heard of it or have a solution. Any help would be appreciated. Thanks

 

MOST LIKELY YOUR ALTERNATOR IS TAKING A **** AND GIVING YOU A HINT TIME TO REPLACE ME. TRY TAKING IT BACK TO THEM WITH THE CAR HOT AND HAVE THEM CHECK THE CAR WITH ALL LOADS ON.
