    Most tachs. run of the rectifier/regulator which also charge the battery, Place a voltmeter on battery posts,take reading,start engine,reading should be higher14.5 Non running reading should be 12.6

    I downloaded a manual and found which wire is the tach wire and hooked it up to 2 different tachs and neither work. I did your test and the voltage stays the same running as not running around 12.35 volts. the manual doesn't say exactly how to check the stator or regulator/rectifier so I'm going to cross my fingers and replace the regulator/rectifier. thx for the help.
