OK, so here's what the voltage regulator looks like opened up. Can anyone confirm for me that the tan component on top with the two red stripes is a diode? I think it is, but it passes current in both directions, so that would be bad.
Does anyone have a good source for these?
What sort of other problems would a poorly functioning voltage regulator cause? I feel like I've been battling electrical problems since day 1 with this car....
