12 volt negiative ground

[denton34@cox.net]

I have converted my 53 merc engine to 12 volt positive ground. I have been told that Runtz gauge voltage regulators are designed for positive ground applications only. how do I reduce the voltage down to 6 volts on the gauges? I converted to 12 volts in order to use an alternator and Mallory mechanical distributor. does anyone see a problem or a solution? thanks steve

Are you sure it's not 12 volt negative ground?

Yeah I'm sure you mean 12v NEG ground, just put 12v gauge power wire on the Runtz voltage input side, it is marked in & out, you can test it for 6v coming out before hooking it to gauges. It takes (1) Runtz reducer for each gauge, seperate the gauges, they have to be fed separately.
