Tach's for 34' Californian
My Californian has twin Perkins 4-236 with mechanical tachs. The upper and lower station tachs are in series with the sending unit on the engine. I would like to convert to tachs that are driven by the alternator.
Question: Are the upper and lower tachs wired in series and then connected to the alternator tach output?
Any one changed to alternator driven tachs?
