Hi all I just replaced my mechanical alternator regulator with an electronic one and all was fine until 30min later when gauges stopped working, I also have a solid state regulator haven't had any problems prior to change over, all fuses are good ran a test on bat and alt at 2000rpm with headlights on and getting a reading of 14volts.
Has the gauge reg carked it, or is there something I should be testing any ideas anyone.
