Hello Everyone,
The ACC2 and EDU on my car (91 9KT) have started cutting out, going completely dark, then coming back on after a few seconds. I am also seeing voltage spikes, 15 to 17 volts, for a brief second, then back to normal. When the EDU/ACC die the headlights also get much brighter. The battery and alternator current output are OK. This all seems to point to the voltage regulator which I'll swap out right away but I'm wondering why the EDU and ACC would cut out at the same time as the spike -- is there something else going on here? Thanks!
