Can any body shed some light on this problem. Lately the alternator warning light has been coming on and off usually happens when I first start heading out for drive after starting but can come on and off at any time and any rpm, volt meter shows no charge when the light comes on so the gauge seems to be correct tried changing the bulb no change. Had the alternator checked it and even swaped it problem was still there. Checked everywhere for loose earth or bad connection can't find anything. Battery is run through an isolator via 100 amp fusible link to the starter and alternator, all circuits are using relays and are fused. I can't isolate the problem I thought it may be related to the immobiliser however if is was caused by the immobiliser every should stop working but the car keeps running of the battery.
Any on got any ideas.
