hi all,when my rs turbo cabriolet was hot it wouldn't start,so today i change the starter,not sure if it was a turbo one but it had the 3 terminals on the starter like the one i took off,the battery was flat so with a push it went drove it for 10 mins turned it off and it fired straight back up,come to it tonight and it fird straight up i then took it out for an hour or so and while i was driving i put it in neutral and turned ignition off and tried starting and it turned slow and didnt start so i put it in 2nd and bumped it,then 10 mins later when i got home i turned it off and it fired up again,so i tried again and it fired up again,tried it one more time and it didnt have enuff power,when you rev the enginethe lights dont brighten up or anyrhing,but it must hold abit of charge because as i said when i left it today it fired up again tonight so not sure weather to change alternator or battery first and if it could be something else any suggestions would be grateful cheers all
