ONAN 5000 EMERALD PLUS GENERATOR HELP

Hello,
New to the forum, and hope some one can help me out.
As having an American Rv in the uk. There is very little help available.
I have a Damon Daybreak, with the Onan 5000 fitted.
Last year the starter motor failed. So we decided to take it out for a major service etc.
The problem I have is, the wires disconnected from the generator are.
1x multi plug connector easy to plug back in.
I also have 5 wires, which were taken out from the generator, which lead into the Rv.
Now it is ready to go back in, I cannot find my drawing of were they went.
2 I presume are from the breakers, as only 2 on the other side of them. But the others could go anywhere, as there are a few options of places to reconnect them behind the starter panel.
Hoping someone can help will try to get some pictures.
Many thanks.

  • the two blacks plug onto the lugs on the circuit breaker switches there on the right.

    pretty sure, because it is 120v only gen, the rest plug onto the lugs under the black box at the top.

    white (neutral) and ground..

    on my 7KW 120v only onan that is how they are connected.

    see the diagram on page 154 of the service manual

  • Hello, thanks for replies.
    Model number 5BGEFA26100N.
    Serial number 1973736415.
    4.8kw 60hz 40amp 1800 rpm 980cc
    its where the wires go inside the generator not the rv end.
    Have took some pictures but struggling to upload to site thanks
  • The standard output wiring will be black (hot), black /yellow stripe (hot) , white (neutral), white (neutral), green (ground) (2 neutrals due to it being a 120 volt model, not 240 volt).

    A model number is really needed for the final answer though.
  • 2 hot legs, color red and black ?
    1 neutral leg color white
    1 ground leg color green

    that only leaves one possibly unknown wire

    which might be from the auto-start control ?
  • In most cases you can find the appropriate Onan Service Manual on-line - it may have detailed installation instructions.
