John & Timmer are both right. In reading the original post it asks if you had to use a voltage reducer with a 12 volt tach. Of course you don't, you'd need a voltage increaser or inverter to run 12 volts off a 6 volt system or a seperate source of 12VDC to power the tach's circuit.
( Man, am I just standing to close to the trees to see the forest?
Does anyone make a 6 volt tach or will I just have to use a 12 volt with a voltage reducer? )
It sure caught me off guard and I didn't mean to post misinformation.
