Re: Onan generators
if the fuel pump isnt working all the time, and it cranks slow, then my guess of course, like you said is that it is in the 12v system... and i would suspect the main leads. my gen set has the ground going to the foot of the base of the generator, and the hot lead to the solinoid inside the panel. mine was doing the same thing, and i cleaned all of the attaching points with a wire brush, and put new larger cables on. I then was able to get the fuel pump to run very well, and the thing to crank over like it should. My gen set is attached to 32 or so foot welding cables that the copper cable itself is 3/4 in diameter. It is a long run.
There are also a lot of connectors inside the panel in mine, with relays, switches, etc, and most of the connectors had some corrosion as well even though the generator only had 19 hours on it... was sitting way too many years with no use...
I am taking the northern route.. try to avoid calif...
