Thanks , anything on a t jet is normally a pain lol mines having a new alternator on Monday due to the fact it was charging at 18.6v when revved up and it was bringing on all sorts of warning lights , I took the alt belt off and it's ok now , no warning lights apart from the battery light and the engine management light , engine light came on when I put a jump lead from gearbox earth to battery earth to check if it was an earth fault , triggered the engine light , hopefully that can be just reset .
