I got it. S-R is Smith-Root. I was wondering why a fish shocker would be using a Switched-Reluctance generator. So it is a Honda generator. I would think that most reputable generator folks could rewind if the windings can be counted and the size of the wire matched up. it should really be irrelevant to them what it does, though most will want to know the output voltage to test it. Does the instructions have any specs. on the generator?
