I have a 1420. With no head on the feederhouse it will raise all the way up and is very slow to lower back down. It doesn't do this with the head on. I'm new to elcetric over hydrlic style. I've only been around cable controled till I got this machine. Any ideas where to start checking?

No need to look anywhere. That is normal. The feeder is only power up. It has to have weight to lower with any speed.

Good Deal. Thanks doorknob. I forgot to add it will raise up and not stop till it reaches the top unless I push the down button to stop.

Does your 1420 have an accumulator under the cab, bolted to the side of the machine? There will be one hose going into it and usually a gate valve similar to what you'd see in your house somewhere with a handle on it.
Turn that valve off and see what happens. If it raises and stops when you release the button, it may be that the accumulator needs a smidge more nitrogen pressure. If so, you should be able to find the needed pressure somewhere in the service manual for you usual header size. Then lots of places can charge it for you. Most dealers, or any hydraulic outlet, even some welding supply houses.

If it dont stop with the valve off, you may have either a switch going bad or a voltage feedback issue somewhere over by the valve stack.
