Hi,
The first two photos show a three wire regulator…stamped 10 amp negative ground. One wire the battery wire, broke off.
The 3-5 photos show a 5 wire regulator…stamped 10 amp pos/neg ground. The additional PTO wire appears to have been spliced from the battery wire within a makeshift harness. Both regulators were purchased with other OMC items in a parts lot.
Beyond that I know nothing!
