Push the start button and hold it in until the generator starts. The clicking is the fuel pump on the Generator.
Just hold the Button down until it starts.
If you push the button for OFF and hold it you should also hear the fuel pump running, this will prime the engine, then push the start button and hold it until the engine cranks. If you have the owners manual, read it and it will also explain the above. If you don't have the owners manual, search online for the specific manual based on the tag on your Onan.
John and Bren, When you push the button do you hold it for at least 15 20 seconds. The generator will not crank until the fuel pump has primed the engine. If you hold the button in the off position, pressing on it you should hear the fuel pump running.
Press and hold the start button for at least 15 or 20 seconds and see if the Generator starts. It does not start immediately upon pressing the button, you have to hold it until it cranks.
Hope this helps.
Bad batteries shouldn't make the Generator shutdown when it is running, with no power to the switches, I assume you tested these with a voltmeter? Would indicate a fuse problem somewhere, or a burnt wire or transfer switch. Did you smell anything like burnt wiring? My Onan 7.5KW also quit like that, burnt wire on the transfer switch. My transfer switch was located in the electronics box under the fridge, wire was burnt in two, and transfer switch was toast.
Also on the left side of the Generator as you are looking at it, there is an inspection door, held on by two 10mm bolts, gen off, unplugged from shore power, take that inspection plate off and look at the terminal located below, mine was completely covered with corrosion I replaced the terminal block and renewed the connections and all my problems went away.
Hi, we carry ours in the luggage compartment just behind the one with the fresh water tank. Ours is an Expedition DP not sure how your layout is.
If you carry it on a ladder rack or such, just make sure it doesn't move and rub a hole in it.
