I just got in a new voltage regulator today. I thought I would post some pictures. There are some cheaper ones out here but I know the Hella brand. This was under $45 shipped. The same ones in the reduced size from Bosch are over $100. Not sure what that is about.

I have gone through a couple of those on the race car
I have had lots of regulator issues
not sure if its the high rpm or what

I keep going back to the metal original regulators
they don't give me as many problems
and I've tried a few brands of the modern ones now...
