Just to finish muddying the water, this 120V drawing for '75 and '76 shows L2 as "hot" and L1 as neutral/ground.

This 120V drawing for a '77 shows L1 as "hot" and L2 as neutral/ground.

Bottom line, when you take it apart and don't label what goes where, you need to use your handy multi-meter to make sure that whatever comes from the Onan circuit breaker goes to "hot" and whatever is left gets wired to neutral and ground.

From delrio's pictures, it looks like the two smaller wires from the Onan come from the circuit breaker. That would agree with the 75/76 drawing. Sort of. None of the drawings I have seen show more than two wires in the flexible conduit (one white and one black).

My '73 23' has a 4 conductor cable (black, red, white, green) running from the splice/junction box to the 50A receptacle. No flexible conduit.

Hope it passes the smoke test (no smoke is "pass).
