LX885 Hyd fault code F OA

[SEW885]

I can not find the problem with my machine with the Hyd not working. Machine keeps blowing the 5amp fuse in the engine compartment. I replaced with a 7.5 amp to try and lift loader arms and with that I get a F OA fault code display on the EIC panel. I checked the boom Solenoids and and they seem to be fine with bench testing them for operation. I just replaced the EIC panel after talking with a New Holland Mech. and not finding any wiring shorts as there where no visible signs of wires shorts of problems. Any help at to what the problem may be would be greatly appreciated.

One of the solenoids is probably bad. When bench testing you do not have any limits on how many amps are going to the solenoid like you do through the EIC and the 5A fuse. Unplug one of the solenoids and start the engine and see if the fault code reappears. If the fault code is still present, then plug the one that was disconnected back in the then unplug the other solenoid. Recheck if the fault codes is now gone.

Hi Mike, Thank you for the reply. I did initially have one sent before bench testing them, but the new part had the wrong connectors and I spoke with a Mechanic who suggested that I bench test the old ones first before cutting the ends off and then not being returnable. Can I run the machine safely without having these in there? I have spent $800 on the EIC panel and each sol. is $180. The machine is a 1999 with only 1400 hours on it and I use it mostly in the winter with snow removal. So I am glad its happening now and not during a blizzard. Also wondering if the machine could be effected by the oil that I have recently put into the hyd. system. I have used a motor oil with a 15w-30 weight to it per the suggestion of a mech. that said a little heavier oil could help with the summer conditions in working the machine as I am currently clearing alot of tress with a Bradco 611 hoe attachment and working it pretty hard. So I guess in the long run 2 sol. and an EIC panel would be short money for the machine repair. Is there anything else that could possibly be the cause of the problem. I've removed the left side fender and inspected the wiring and do not see any visible signs of shorts.

When installing new solenoids in older loader I use a modified harness extension NH has. The following is my notes on what to get and how to modify the extension. Not complicated or expensive and keeps the wiring intact on the new solenoid. ........................... WHEN REPLACING THE SOLENOID ON OLDER MACHINES ALSO USE A MODIFIED 87048133 WIRE HARNESS. WHICH CONSISTS OF 1 87048133 HARNESS, 1-256340A1 HOUSING, 2-221381A1 WIRE ENDS, 2-15324973 SEALS. OR 1- 256340A1 CONNECTOR, 2 - 221381A1 TERMINALS, 2 - 15324973 SEALS TO MODIFY EXISTING HARNESS. ......................... TO MODIFY 87048133 HARNESS, REMOVE PINS FROM MALE METRIPACK HOUSING, CUT TERMINALS OFF. REUSE SEALS. INSTALL 221381A1 TERMINALS. INSTALL TERMINALS IN FEMALE HOUSING 256340A1 PLACING BLACK WIRE IN THE B HOLE OF CONNECTOR. 256340A1 SAME AS 12052641 FROM PERFORMACE CONNECTIONS SYSTEMS...................... Hyd oil us 10w30
