Permanent magnet alternator, with a regulator that shunts excess out
voltage to ground?
A permanent magnet alternator would have three AC output wires. An
excited field alternator would have two more wires which are DC input
and output for the rotor.
Also, count the number of wires on the regulator.
There are probably three AC inputs, a + DC output and a - DC ground and
a sixth wire which is a remote sensing wire that goes up around the
dash somewhere.
The sensing wire can cause all sorts of problems, as excess alternator
output is never shunted to ground if the sensing wire "sees" low
voltage.
Shunt regulators used on Yamahas and Suzukis will only have five wires,
because voltage sensing is inside the regulator, where it should be.
