Just fired up the Onan! Still have to sort fuel line and pump issues, used gravity feed and a little external fuel.

The problems were easy - points were nice and new but corroded at the contacts, and ironically the fuse was good but the contacts on the board corroded too not allowing the circuit to close.

Cleaned up those things and she started right up and idled nice!

More to come as I try to figure out the fuel pump circuit problems.

Like Terry says. Long periods of inactivity on Onan engines will nearly
always result in some slight corrosion in the contact breakers. A points
file or in lieu of that a fingernail file, NOT AN EMERY BOARD OR SANDPAPER,
a few quick strokes through the closed points followed by a business card
to clean the residue should restore the points. A quick visual check to
verify that the points are actually opening, and you should at least have
spark. If that is not the case, save trouble down the road and install one
of Gary Bovee's electronic ignitions. Set it right, and forgetaboutit.

Clean the points. Check for fire by shorting them with a screwdriver when
you are cleaning them.
