    MEP-831a Troubleshooting

    I'll have to check tonight. In the video above you can see the amount that is above the lever. Not sure if that is helpful or not. When we adjusted the rod length, I screwed the rod out from the spherical end.

    MEP-831a Troubleshooting

    Dewie, any suggestions on how to address my shut down issue? Please notice that even after adjustment, my readings are still out of spec. Not sure if I should be concerned with this or not because I have no operations complaints other than the shut down issue. I'm still not certain the gain...

    MEP-831a Troubleshooting

    I'm wondering if maybe the speed controls are way out of wack? If adjusted even slightly wrong youl'll get a surge and it's not much further before I could see a nasty surge like that happening. There are a couple of sections detailing how to adjuust the speed control unit. I'd tell you where...

    'Fraid not. I shot the video after hitting it. In the video, does it look like I have the gain set correctly?

    YES!!!!!!!!!!!!!! OE Yanmar parts are so cheap that it's a waste of good money to look elsewhere.

    Here is the requested video: http://youtu.be/TCeTP-gOmz0 I tried locking the lever up and hitting it with my fist and it felt very solid.

    MEP-831a Troubleshooting

    Thanks for the reply. Can you check my prior post (#157) to see if the governor set correctly? I'm still not getting readings within spec and I think I may have misterpreted the gain setting.

    Post where you found the hose. I have a leak on mine that I thought was the sending unit but it could very well be the hose. Can anybody tell me how to adjust this unit so it'll shut down? Also, how is the hardware configured for the lid hold-opens? The pin is exactly the same size as the...

    Yes, I replaced mine, very easy job. How far along are you? If you don't have the head off, I can give you some additonal pointers. A while back I had uploaded the engine service manual here...

    MEP-831a Troubleshooting

    Right now I have the gain set so the magnet doesn't touch the target. Based on your response above, I presume it's Ok to touch so long as it doesn't "grab"? Yes, correct the engine slows down and then the magnet releases.

    MEP-831a Troubleshooting

    I checked the section numbers against my manual and it doesn't match up (there are two different versions of the manual out there, data is the same but it's arranged differently) so I don't know what P17 and A8 are. I assume the reading was intended to be taken directly across the two gauge...

    MEP-831a Troubleshooting

    Ok, finally got back out there and did some more testing. This time we used two heaters, but of which were rated for 1,500 watts. Not a true load bank, but the best I have. We also took great care to follow the instructions in each step. The only exception that I found was adjusting the...

    MEP-831a Troubleshooting

    Ok, well that explains why the switch doesn't drop the load. One problem solved! I attached the procedure I followed to adjust the speed. I set the speed to 254Hz, but I didn't adjust the linkage and I think I skipped step #9. I think I'll go back to reset the unit again to be certain I got...

    MEP-831a Troubleshooting

    Sometimes it does. Other times it will show a 1500w load as 3,000 watts and rising. Usually at that point I bail on it and switch the load off. Right now it shows the load as something trivial like 500 watts. Dewie38 says there should be .857 ma at 3kW load at the back of the meter. I'll...

    MEP-831a Troubleshooting

    Load and no load frequency is 60hz. Nice and stable. I have not tried more than 1500 watts because the outlet is labeled for 10 amps max. Ultimately this unit will be mounted on a atv trailer, but I'm waiting for the frame to come back from the powdercoater. I found a local company that is...

    MEP-831a Troubleshooting

    Bump. Not sure if I continue to invest in this unit or if I should just bail on it. It's making power and all, but some of the voltage readings are out of spec, the unit won't power down, the circuit breaker won't open and the load gauge readings occasionally go wacky. I'm guessing all the...

    MEP-831a Troubleshooting

    Well, I just got a new multimeter so I could read the Hz. The low speed was set correctly, but high speed was low. I adjusted high speed and then checked low and it was off. Went back and forth a couple of times so both settings were at spec. I then went back and reread the voltage readings...

    MEP-831a Troubleshooting

    Really? I thought that almost all the values were out of range? The the target hits the magnet and holds there until the engine slows. At that time the magnet releases and the rpms rise to a idle. Pushing down on the arm will shut the engine down but the magnet won't hold. Seems to take a...
