drifter17a Posted August 9, 2020 Share Posted August 9, 2020 All, had car for number of years all good. Changed to big turbo and around 650bhp and after 2 days of driving alternator suddenly died it is much hotter running car so thinking it could have killed it. Very strange no sign and suddenly dead do they have a relay or something? If i remove battery lead, it dies and don’t charge checked online and some say it could be relay. Is there relay for alternator ? looking at high amp ones they are £600 so pricey. thanks for any advice Link to comment https://www.sau.com.au/forums/topic/480933-r34-alternator-died-suddenly/ Share on other sites More sharing options...
KiwiRS4T Posted August 9, 2020 Share Posted August 9, 2020 Personally I always like to get a quote from an auto electrician for a rebuild before splashing out on a new one.

GTSBoy Posted August 9, 2020 Share Posted August 9, 2020 Personally, I always like to make sure what has actually died before splashing out on a new one.

What part of the alternator has died? Rectifier? Winding gone open? Dirty commutator? Diagnose properly, then fix. If this means taking it to a sparky, then do so.

drifter17a Posted August 13, 2020 Author Share Posted August 13, 2020 So took it to sparky and he reconditioned it. he couldn’t get the regulator and after some fafing around he called and said it is ready So now with full load it is charging at 14 but when rpm is 2k and above. When on idle which is around 800 it doesn’t charge at all with full load charing at 12.7 or less with nonload or full load around 11.5 belt is as tight as hell so what could be wrong?

drifter17a Posted August 13, 2020 Author Share Posted August 13, 2020 Did voltage drop test and negative it is 2.4 volt and positive is 3.4 volt to alternator and i belive more than 2v on positive and 1v on negative means trouble my battery is in boot so i used jumper lead to extend so not sure if this is playing a role i think it is either dirty connection or short circuit somewhere, thought?
