Default Onan 3.0 DJA Help

I am the new owner of a great little 3.0 DJA generator. I got it to start yesterday, but the switch to shut it off would not work. In order to shut it down, I shut the fuel off.

Now the problem. I replaced the start/stop switch, but I seem to have an extra wire. Does a home have a wiring schematic for it?

I put the wire hack on the terminal I thought it goes on and it will crank fine, but not start. I tried cracking the but of each end of the hard fuel liine to bleed it, but no luck. I also noticed the wire that goes to the little nut on the intake, just above the air cleaner was smoking a little if I held the start switch down too long.

Any suggestions?

It says 3D-SL 1R/1B for the model and spec number. Is that what we need?

You do not have a DJA, you have a DSL.

That one doesn't have a schematic for the control box. That is what I am needing. Any thoughts on bleeding necessary to starting after shutting off the fuel?

Your wiring diagram number is 610C99 on page 72 of the 936-0001 manual in the above link.

I really appreciate the help. But in my download, that is starter information. I need the wiring diagram for all the wires inside the box where the switches are. I replaced a switch and seem to have an extra wire.

I also ran it dry on fuel to shut it off. What is the best procedure to restart It? Does it need to be glad of air?

Thanks....great site!

That diagram is "all the wires" as the set was when it left the Onan plant.
