I have a sw48 with a chysler 231, well anyways the other day I was "testing" the blade out on her and she quit , no sputter no nothing, just died. I pushed it back into the shop and no spark was found, well OK, I had another coil, so I tried that to no avail, then was looking for the regulator, well, I cant find one, is it built into the alternator? I will also change my points and condenser with new cap but all that is on order. I guess my question is only about the regulator, if there is one.
