Re: One Wire Alternator problem
Are you sure it's not a 3 wire (a.k.a. 5 wire) alternator such as a CS130? They can be wired as a 1 wire alternator, but the brown lead (that typically is connected to the GEN lamp) needs voltage applied to it to excite the alternator. If you don't use a lamp, you can connect the brown wire to the B+ lead, but you need a resistor in series with it to limit the current. If it is in fact a 1 wire alternator, then disregard.
