Hi I've been having a problem with the speedo, rev counter, fuel gauge and radio going crazy, also the engine cuts out, The battery over cooked. Took it to a Chrysler garage who said it was the alternator over charging on tick over and it needed changing. They wanted to over cook me by charging over £600 to change the alternator, so I changed it myself. After changing the alternator I let it run 15 minutes while I cleaned up. Afterwards I went out onto the dual carriageway and within 5 minutes the same problems were back. Anyone any ideas? thanks
