Our boat is powered by a single Ford Lehman 120. The electrical system/alternator is a stock unit which I believe to be about 55 Amp, the tachometer signal is derived from the alternator. I would like to upgrade the alternator to a larger unit, say nearly double the output. I have heard that there is a "Balmore" unit that can be installed. What all is involved with upping the size of the alternator. Please keep in mind that I need to get the tach signal from the new alternator. The reason that I want to increase the alternator output is so that I can get a better charge on my house batteries and decrease the run time on the generator set.
