Hi mate am sure everything connected will look again tomorrow, its had new alternator and battery, I just dont understand the noise when you let off as it only started when the light came on. Would light come on if starter jammed on? As then it would be taking the power away? BEats me am crap with eletrics! Any help would be great I will get a hold of readings to let you know what it at. Cheers and o the headlights etc stay the same when revved
