Weekend Warrior Onan 5500 install help

Hey guys. im having issues with my keyboard so sorry or the typos.

i have a WW s2600. it was missing the Onan 5500. so i stumbled across one on CL or $1500.....40 hrs...deal o the century.

now...what and where do i start with wiring it up. im not sure what i am missing, can anyone take pics o there gen compartment and cord/inverter compartments. so i can get a good visual on what i am missing. gen is complete. has 6' o wire (pos/neg) How do i hook these to dual batteries?

and 6' o wires (2 lack, 2 white, 1 green) where do these go? is there supposed to e another outlet in my compartment to plug the shore cord into? i am confused since every manufacturer is different.
  • The short version:
    - Connect the two wires for the starter to a 12V source.
    - The other wires feed an outlet in the compartment your shore power cord is in, the shore power cord plugs into that outlet to use the generator.

    On my 2005 WW which has an Onan Marquis 5500 Gold this is a 120v 50amp outlet which my shore power plugs into. The power feed from the generator is two 30a 120v circuits.

    If this is the first time you have worked with 12v and 120v power feel free to consult an electrician, even if it's at the very end. Melting any parts will cost more to fix than the electrician.

    If you have a multimeter you can test everything yourself. If you don't have one go buy one, the inexpensive ones will do everything you need.

    Congrats on finding the genny!
