Onan Generator connection to 4x4 junction box

[Alfalfa1969]

I have a 97 Winnebago Adventurer. I pulled the generator out to install a new carburetor. When I went to re-install the generator, I forgot to mark the wire. I have a 10 ga black wire and a 12 ga black wire leading into the motorhome thru the 4X4 junction box. The wires coming from the generator I have one black stranded wire and one black with a yellow strip stranded wire. Which wire will connect to my 10 ga wire going to the motorhome?

Awesome. Thanks. I will hook it up when I get home. Thanks for the quick response.

The 10 gauge goes to the Motorhome 120 breaker panel. The 12 gauge goes to the Rear AC. The Black with yellow usually goes to the rear AC(the 12 gauge) and is on the 20 amp breaker on the Genset. The other black wire comes from the 30 amp breaker on the Genset and goes to the 10 gauge. Doug
