Adding: The last three or four years (since I replumbed to one regulator on the tank) the generator ran great.
This is the first time (two weeks ago and now today, with propane) that I attempted to run the generator since it was in storage for...

Oil was 1/2 qt low. Now filled right to the full mark.

Remote toggle in the bedroom doesn't work. Start/stop toggle on the face...

I had an older Onan (1981) gas generator on my previous rig and that generator had similar problem once. Turned out to be a bad relay.
If you can't find a solution by searching Google, your best bet may be to have it serviced by an Onan Service...
