Would like to know if any one has seen these on a gauge before? The one is a 12v and the small button thing is on the hot wire. I am trying to see if I have 2 12v gauges, as I am going all 12 volt. Thanks To all. Tom Y
I have seen this sort of thing at a street rod/custom shop. They are used
to drop the volts from 12vdc (upgraded) to 6vdc. The purpose is to change
a early street rod systrm to 12vdc and still use the origional 6vdc gauges and
sending units etc.
