The original Sun did use a sender, and they used a mercury battery. If memory serves me right they were 2.3 volts. I found an NOS tach at an antique mall, and bought a sender off of eBay. For grins I tried a normal AA battery, which is 2.5 volts? I dont remember the Co's name off the top of my head but they can covert them over to solid state.
