E.I.C. 86625316 board

[mecster]

Hello All, I just rebuilt my LX-885 322t and turbo and runs great! After 50 hours on the new rebuild it started to beep and lock out the boom hydraulics then the machine started to shut down. After 10 min it could be started and run, then the problem would begin again at at different intervals. Finally the EIC Instrument cluster would not light up at all when you sat in seat. However, machine ran in service mode. I checked the safety interlocks on seat and safety belts and checked the pin voltages and ground at the EIC using the service manual. I then determined it was the EIC board at $880. I then purchased one from Messick's where I see they stock 8 of them. After contacting a number of sources I am finding out that this is a problematic part and just about everyone who I contacted has this model has sometime replaced a board. After replacing the board, the rpms are off by 500 rpms and the hour meter does'nt work. I was told it needed calibrated for the hours and I checked if it was on the setting for the 3 cylinder diesel and it was. Can I do this myself?? Mecster

There is no calibrating for hours. A dealer can change the number of hours displayed, but that is all that can be done with hours. I would again check to see if you have the correct model selected. The rpms are determined by the alternator connection. I think this also applies to the hours. If your alternator is not working right you will not get the correct rpm displayed.
The fastest way to check is take your board to another machine and see if it works there.
Though the EIC's are not perfect, there failure rate is quite low. The only exception are the early boards that had silver trim lines around the instrument panel lights. The newer boards have gold trim lines. There are two types of silver trimmed boards. Those that have failed and those that will fail.
Many times the EIC or for that matter any computer on a machine is the first thing to blame and replace when there are other causes. I would suspect that is what you found with your inquiries.
By the way, if you had a gold trimmed EIC it could have been rebuilt.
If you had a silver trimmed EIC, you got the wrong replacement panel, though the operation is the same.

New Information from Messicks the E.I.C. board was not programed for the Lx-885 they come from the factory with the LS-170 program However, I have to send back and get it programed for my Machine.
