OLT, a very simple question regarding this exhaustive subject.

I have a 95, with 60K. No problems in the clusters at all. But, I LOVE the setting on "High". Does having the switch on high versus the spot right before the "click" increase my chances of losing the cluster/needle lights quicker??

It is referenced by several, but at the same time I read that the related heat from the high setting isn't a factor. So, your expertise is greatly appreciated, I would rather dim it a bit and save the hassle later.

Thanks a lot.
FYI, the setting full on is 8.4 volts. the setting one click below is 8.3

the threshhold on the needles is 8 volts. oversight?

I'm almost positive on this, if anyone cares to elaborate or fix what I said, feel free.
close.... very close. The contacts and the plastic BOTH become brittle from the heat, but the high output of the OPAMP inside that pushes .4 volts (almost half a volt too much) is what does it.

Somebody messed up. At any rate, I'm leaving it one click below because so far, so good.
May not be the most scientific decision, but I'm sticking with whats worked for me so far
