Just scored a Onan marquis gold 5500 gas genny for $1250. Less than three hours but prior owner says in won't prime but works if you pour gas in the carburater. After explaining this to multiple service centers, all say replace the carburater??? Someone probably left fuel in it. Seems it would be a fuel pump of some sort but I cannot source a REPAIR manual for this unit to see what standard equipment is. A wiring diagram would be great but the manuals I found on cummins/onan site are little help.
Anyone happen to know where to source a REPAIR manual?
btw I have officially spent more than the bus itself with no light at the end of the tunnel.
I had to go to the cummins dealer and have them order the manuals for my genset, take the model and serial numbers with you, you will probably have to get seperate manuals for the engine and alternator ends.
