MEP 806B CIM Failure

[Bakerman]

Hello everyone,

I am new to this forum and I have found everyone extremely helpful. I've got a predicament. I'm an electrical contractor in South Carolina and a small Fire Department purchased an MEP 806B 3 phase Diesel Generator. We connected it to a manual transfer switch so it could serve as an emergency back up generator. When we first installed the generator the CIM was very DIM and was most likely sun faded. The customer took it upon themselves to replace the screen with a compatible LCD screen from eBay. Well, then the problem became that nothing was legible on the screen. Thankfully 155mm helped me out and lent his Dimming adjustment tool to me and I have since corrected this. Now that I can read the screen we have another issue. The CIM keeps performing it's initial boot on loop. I have a communication failure light on as well. I opened up the CIM (using ESD controls) and found what appeared to be salt water deposit inside the CIM. I carefully brushed the deposits off with no change in CIM performance. I've attached a picture of the screen it keeps looping too. Any and all help would be much appreciated! Thank you

Looks like it's stuck in POST. So basically it does it's "power on self test", then looks for bootable media. It doesn't find any, so reboots to try again. This is the boot loop you're seeing. My advice is to go check the TM's and troubleshoot the bootable media. I believe there is a CIM troubleshooting manual in the TM's section. I would start there.

Thank you for pointing me in the right direction.

Manuals for the MEP-806B

Here is the TM's needed to work on the MEP-806B, EXCEPT for TM 9-6115-672-14. This manual is too large to upload at this time. Be aware that there is other files and information pertaining to the MEP-806B in the TM's forum. So LOOK for them.

MEP-805B and MEP-806B CIM Info

This is some info i received from a friend. Some of the info is old, some of its good. Better then nothing in any case. Still haven't found the software yet, but haven't given up yet!

There are a couple of links to the TM's. I believe the second one may be redundant, but included it anyway.

These sets are a POS, you or the customer will spend way more $$$$ trying to fix something usless and never have the assurance it will work the next time needed. My experience is rip out the whole mess, while i do reuse the regulator and gov nothing else remains.. Its a freeking technician nightmare and typically built around Windows 97 support. rebuild it using convential systems and you will never look back, to date i have scrapped 18 of these and have not looked back one time nor has a single customer...BTW i do think there is for sure 3 versions of the CIM possibly 4 early were monochrome and later had color and more firmware changes .. best: mac/mc

How do you bypass the CIM? Mine is burned out

You don't bypass the CIM. How do you know its "burned out"? Whats wrong with it?

What are you replacing these SIMs with? Same unit in 805 and 806.
