Re: Generator putting out too much power

There is only one screw to adjust, but when I back it out some, it does not make contact anymore nor does the RPM lower anymore.. I can physically push it till the screw makes contact again and the RPM is lower, but as soon as I let go, it goes back into place. There must be more to that setting.. I don't see any kind of voltage regulator on this unit.362Views0likes0CommentsRe: Generator putting out too much power

So I can get it down to 120 range, but the engine seems to be running too slow.362Views0likes0CommentsGenerator putting out too much power
Hello all! I have an Onan 4.9BFA 4000w gas generator. There is a plug on the cable the way it was sold to me. The PO used this for a race car trailer to power one AC unit and some lights. He said he had no issues.. I would have to say the lights must have been really bright. Here are some pics of what I have.. Below is the reading while its running. Here is where the other end of the wire is. Here is the schematic of the model I have. What im not sure is, is it hooked up correctly? I tried testing different points on that termimal block and I either got 0 volts or 148 volts. Nothing in between. Any advice would be helpful.1.6KViews0likes9CommentsRe: Water heater not lighting

The module looks different than the one I have but if you turn it over and see a circuit board and soldered joints you could look for burned out tracks. If it is potted like mine is you have to test with an ohm meter. This one is a sealed unit. You cant see the board from the back.379Views0likes0CommentsRe: Water heater not lighting
Unfortunately I do not have the manual for this unit.. When I this box out on my desk, I noticed bug parts falling out of it. I kept tapping it on the desk and at least 6 dead lady bugs fell out if it. There are open hole where they can get into it. I reinstalled the unit and it fired up every time. It fired up 10 times in a row yesterday.. I tried it again this morning, it did not lite the first time, but did every time after. When it does not lite, you don't hear anything. When it does, you hear 4-6 spark attempts then it fires right up. I do not suspect the gas valve at this point. When its lit, it is burning fine. Good flame and all. This unit was built in 1992. What is the likelihood this box is on its way out? I have found replacement modules online for $120. In my local RV stores they are around $200.379Views0likes0Comments
