hey-Hey!!!,
My 1990 is eating voltage regs. I scoped the battery looking for a shorted diode in the 3-phase bridge, but saw nothing useful( liddle ripples, all the same size ). I tried measuring the voltage reg case to batt negative voltage and got a steady 39 mV( black lead to batt, red lead to reg's case ).
Am tempted to start throwing parts at it, but I'd rather just fix what's broken, yes?
cheers,
Douglas
