Well, got some things soldered together. The little black square 7808 regulates the 12 volts down to 7.3 volts, then the diode drops that down to 6.7 which is right in the normal zone for a 6v system. Then the round transistor takes the 'signal' voltage from the 7808 and puts that out with a higher amperage for your 6 volt things. There are also 2 small caps and a resistor in there to keep the signal volatage stable. Tested ok last night with my multi meter, and will soon try a test run with gauges and clock. In the pic you can also see my dash gauge voltage regulator.
The casing of the 7808 is conected to ground, but you don't want to actually ground it, that is what pin 2 (middle) is for. I think that is how I smoked the last one, Also, don't swap polarity. I still have to mount the 7808 on the cooling ribs somewhere and insulate with plasti dip. Then hide under the dashboard.
Hope it works.
