    Hello guys. I am new here and have been searching from some answers for a week or so. I recently purcahsed a used e47 plow. My problem I am having is that the plow angles left and right fine but will not raise. When I go to raise the plow, it angles left 90% of the time. From searching and the troubleshooting flow chart, is says check the b valve. I have checked the b valve and it seems to be working properly. I applied 12volts to each valve and the b and c valves make an audible click. Does this mean the valve is working properly or could ther be another problem even if they click? When I went to check the a valve, it did not click. Pulled the valve and the coil was stuck to the valve. Also sometimes (less than 5% of the time) when I go to angle right, the plow lifts. Would a faulty a valve cause all the problems or is it likely something else also. Thanks

    A defective (sticking) B valve and/or a control/wiring harness issue. The only way it can lift instead of angling right is if the B valve is stuck open from the last raise function or the controller is sending voltage to the incorrect coil, thus it can be a control/harness or B valve issue. Need to do further diagnosis to determine which, or if both are faulty.

    Hi B&B since we are talking about E-47s which do you like better the ball coupler or the pin style coupler?

    Thanks Mike

    I prefer the pin style but they have to be of good quality to be reliable. No aftermarket generic brands.

    Thanks for your replies. I had a feeling I may need the b valve also. One other question for you. I see they have different shaft diamteres for the a valve. If you swap the complete valve and coil can you use either size, or are the valve end different?

    Correct, as long as the coil and valve stem sizes stay matched you can swap between them.

    Buy the one with the larger stem, much more durable:nod:
