Renault Clio 182
Took My car out this weekend, drove 30 miles or so as i was going shopping stopped for petrol on the way and the car struggled to start up, when i returned from shopping my car would not start at all so i had to bump her to get her going again as i was returning home most the lights on the dash came on and the speedo and rev counter stopped working under hard acceleration they came on then again turned of then my car litterally started juddering in traffic and completely stopped, then nothing the car would not start at all so i towed her home and got myself a new battery i also checked connection to the alternator that seemed all fine, however since putting a new battery in when you start the car up the stop light and battery light come on until you rev it for say 30 secs and it goes out so i am now thinking it may be a new alternator put a volt meter across the battery whilst running there is no increase or decrease can anyone shed anymore light on what this could be
Thanks in advance
