Earlier this week all warning lights came on the dash,tried cleaning and making sure connector wasn't loose,no joy,so took alternator of and got it tested and repaired cos the regulator had gone and the rectifier i think he said,Iput alterntor back on and fired it up,lights still on,but as soon as I rev it they all go off,drove it it and its OK no lights and voltmeter shows its charging,but as soon as I turn engine off then back on the lights come on again until I give it a rev again any ideas anyone ?
