It sounds like the burnt switch problem that the Sedona's seem to have. If you are confident enough, and can take a switch apart, but you will be dealing with tiny springs and contacts etc. then take it apart and carefully clean the internal switch contacts (just a quick rub with fine wet/dry paper on the contacts will do it) The tricky bit is putting the switch back together. Other than this it could be a loose connection on the wiring plugs which I would check for first before tackling the switch, BEWARE do not take the switch apart in the car, take it off and do it where you are less likely to lose any bits. You could buy a new switch.
The pressure switch is assembled by automation and is basically impossible to put back together by hand. Even if you did manage to get it back together, the adjustment if critical. Easier to replace with generic pressure switch. Order from ebay for about $15. Just pay attention to port size and cut-out pressure. Select a switch that has on/off ,several ports on bottom and cut-out from 125 -135 psi. Factory switch is too expensive and really not any better. Good luck
I have this exact Jin-You E70469 switch. Forget a replacement unless you drop about $20 on ebay. Westinghouse replacement switches did *not* work for this type of switch. Here's the solution that worked for me: CUT THE POWER and test before you touch anything electrical. 1) Diagram the wiring configuration of the switch noting where things go---take pictures. 2) Take out the wires that connect to it. Use a paper clip to spread the clips to pop them out. If you have any wires that come out and back in the switch itself, you can leave them attached. 3) See those pins that keep the housing together? Get a drill bit---or Dremel tool---just slightly bigger than the bottom of the pins. You're going to drill off bottom/rolled over part of those pins. Take it easy. LEAVE THE PINS IN. Do not take the pins out. With the bottoms of the pins ground off gone, now take off the nut that's threaded onto where the chain comes out. Now, carefully pry apart the bottom of the housing. Take a picture. Notice the position. Notice the position. Now, pry the little closure carefully just a little and replace the chain. Put the spring back exactly how it was. NOTICE the little finger in the bottom cover where the spring catches to snap it back. Put the bottom housing on. Holding the whole thing together, try the switch. If it doesn't recoil, pry it apart again, and adjust where the spring catches. This part will annoy some of you. Test again. If it pull ans recoils, you've got it. Put the nut on. Put electricians tape around the housing---don't cover any inputs. Re-insert your wires according to what you had. Put back together.
the rope rotor will go on first, then the washer goes on, put the dogs in then put the spring on. insert the rope into the rotor, wind it up, feed the rope through the starter cover, carefully allow the rotor to wind in the rope a ways then put the handle on.
Ignore all the other comments, they are wrong. The feed dogs are driven by the feed driver mechanism, turn the hand-wheel forward and the feed dogs will come up. (Providing you have the feed dog switch to the up position).
Susan Sylvia is exactly right. I just fixed my tool with her information. I would add to be very careful not to disturb the 2 small springs(associated with the trigger and safety mechanisms) and take note of how they are positioned. Also, the screws seem to strip unusually easily so be gentle when removing and replacing them.
When it jams, does the paper get bent or crinkled? If so, there is probably something lodged in there causing the paper to stop. Could be a paperclip or staple, or maybe another piece of paper.
If there is nothing blocking the paper and it just stops feeding on one side, you may have a tension problem -- springs might be getting old and not pushing rollers together tight enough to feed the paper. If you can take the machine apart, try switching the springs around to see if that makes a difference.
