Hi, I have a one wire field alt. Question is the one field across from the battery post is it supposed to be ground too? The one at the side is grounded and when checked with ohm meter the other one is too to the case . It was pulling 15 volt and the volt gauage was bouncing 13-15 V. For fun tried a square back one 90 amps volts was steady 14 when just fired.
