One more thought...you can take off the generator belt and spin the generator by hand (engine not running...watch out for that fan!) to see what kind of voltage (positive or negative) you get across the generator terminals. Make sure you spin the same way the belt want to turn it.

I recommend spinning by hand to see if it is positive or negative as I describe earlier. If it is negative (red lead always on chassis), run it as a motor for a second or two by jumpering off the battery (again, belt disconnected). Then, spin by hand again to see if you have 're-trained' it to produce the proper polarity. Once it reads the same polarity as the battery (you get a positive reading with red to chassis and black to the terminal) then you're ready for business.

Hope that makes sense and works for you.

Elliott said while this ... [Read Article]
