power gear elec. jack problems

[f-4 phixer]

PG problems from delivery Jul. 07 to date.Dealer tech worked on jacks & fix lasted 7 days. Dealer installed updated "OG" revision control & harness. June 08 new control installed by dealer. Nov 09 put unit in storage - dry climate w/ jacks down using auto mode all lites off. Feb 10 released emergencg brake & turned ign sw. on not start pos. & M,A & 4 diam. lites start blinking. LF jack leg has fallen 4 times. Using tip sheet 11001 all jacks pass item 6, but RF fails item 7. Ex tech installed new control & jacks oper. 8 times ok. then failure. Yesterday I reinstalled old control & jacks operated ok for 2 auto ops. Worried when driving LF may fall so will safety wire jack up for the trip. All wiring shot from touch pad & checks good. Can not talk to PG so no help there. I can apply power at jack elec plug on control to op. the jacks if needed. There is control revision "OK" out now. Any suggestions?

I'm really interested in your situation as i have had a brake problem in one jack, however your abreviations escape me. Please restate your post more fully.

I'm a 55 year acft. mechanic still working on planes. Not to smart, but acft. get in your blood & we use a lot of short cuts in writing . Sorry for that. The abreviations are M = manual, A = auto, Diam. = Front, Rear,Left & Right Diamonds on touch pad. Ops= 2 operations of the jacks. I disconnect the power plug at the levelling control & supply power on the jack side of the plug if the jack will not extend or retract under auto or manual control which happens to often. I have down loaded about 5 Tip Sheets from the" PG" power gear web site 11001,11002 & 11003 etc. & they have good trouble shooting techniques. At least the control is easy to get to & 12 volt power is in the same compartment on my Bounder. "OK" revision costs about $450.00 which I'm not happy about parting with. Hope this clears up my previous entry. Dick

Dick - a couple of things to check but first thing is thats a very dangerous situation with the jack falling down on its own and I would take it back to the dealer and do not take it out of there until its fixed - a) there is a procedure that has to be done before the jack system is used for the first time- each manufacture has ther own and this procedure orients the control module with the leveling sensor(s) in the coach - if this is not done then problems such as you have will keep occuring- this should have been done at the factory and the dealer with the new control but was it? - I have had to work on several new coaches that were not preset at the factory and after going through the procedure the system worked fine- this may explain the control part of your problems b) the jacks falling down is a hydraulic system failure or there is one other possibility - the hydraulic control valves have provision for opening up each circuit going to each jack so that in the event of a system failure you can retract the jacks manually - the valves usulaly have a knob or allen screw in them so that you can temporarly open the circuit, retract the jack and then you return that adjustment to its original position so that the jacks do not fall down - this will be in the PG sevice manual for your particular system and it should be checked to make sure these valve adjustments are where they are supposed to be - as I said the selling dealer is responsible for making sure your RV is safe when you take delivery- problems do happen after the fact but its still under warranty -let us know what you find.

Thanks for clearing that up.

Sounds like you broke a shear pin in the jack that keeps falling down. PG sells replacement pin but you need to adjust the jack as it is traveling to far and breaking the pin. I think the rev.OK addresses this but not sure.

There have been updates to the rubber boots and the clamps that hold them in place. PG will give them to your repair facility for free. I put silicone at the top of the boot all around in an attempt to keep the water out. The water intrusion is the killer of these brakes. It corrodes them in no time. That's all I know.

A question for you- when you apply power to the jack , do you do it to the plug that's on the jack itself or do you do it to the plug on the control board?

The previous poster thought you had hydrolic jacks. That happens a lot as power gear also makes them.

Good luck and please keep us posted.

Cliff - thanks for pointing that out - maybe I should read the title first!!! - that's what happens when you work overtime on a Saturday on Easter weekend to get customers RV's back on the road for the weekend!

Oh boy...here we go again Cliff. I've used my jacks three times since I replaced the brake. So far so good but I'm still calling on the "big Guy" for help.

Its interesting we all have the exact same problems and we all get the same results.

f4-fixer, whats this OK revision for $450? Also, do a search on this forum and you'll see that Cliff and I are the Power Gear gurus...whatever that's worth.

Yes Jim it's just like a mulberry bush, as we go around with these power gear problems. The rev.OK was the latest and greatest which I'm told replaced the control board and wiring harness. Mine, thank the big guy has this one.

Hope all else is well .

I remove the connector at the levelling control & jumper power to the jack or female side of the connector. Its easier than laying on the ground ( 76 years old). I agree that something is not kosher with the left front jack shear pin or what ever. It will operate 3 or 4 times & then fall. After pushing the leg up it will operate again for a few tries & then fall.

Be sure to inspect magnet and sensor aglinment and operation, if your system is using the two plugs at each jack. Then once repaired, you have to run each jack down about 4" and do a clear fault & reset. If you loose the correct level on auto leveling then, do a zero point reset.

That sure doesn't sound like a shear pin. Have you called Fleetwood tech support and run the problem by them? Keep us informed.
