Customer Question

I have a Yamaha EDL4700S diesel engined generator. Engine starts but doesn't build up to full load revs and isn't generating power. What should I heck for?

First you need to fix the engine rpm issue, once this is done the power issue will most likely fix itself. I would look at the fuel system, you may have air in the fuel lines or system which would cause the engine to not run properly. This is the first thing that I would look at.

John, thanks for the reply. I'm afraid it's a little more than the fuel supply to the engine. Yesterday I stripped off the side and end panels of the sound proofing box so that I could get sight of the generator etc to discover that there had been a short in the control wiring and a number of the wires were burnt and, in some places fused together. My thinking now is that I must replace this visibly damaged before looking for other problems. Can I come back to you when I have done this if I'm still having problems? Regards, ***** *****
