XC43 Overload on all current outputs
Has anyone ever seen overload errors on all of the current output from an XC43 or have any idea what might be causing this?
This is an MD4-10 running on V 6.01.6 connected to a diesel engine on CAN A, XC43 on CAN C, and qty 2 LC5s on CAN D
This is an intermittent issue. Sometimes they will go a day without any errors while other times they see them every couple of hours or so.
This machine did have an alternator failure recently, so we initially thought it was a damaged XC43 module from possible voltage spikes from a failing alternator, so we replaced the XC43. The new XC43 worked for a day, but then the errors came back. All of the wiring looks good and we're told the new alternator is putting out a steady 27.5-28V.
I'm leaning towards replacing the MD4 and updating the firmware hoping that will fix it, but I'm kind of grasping at (expensive) straws at this point.

I would definitely update the firmware to at least 6.08 as there were firmware updates for Can C&D co-processor (it may be required with a newer MD4). Can C and Can D are slower than Can A and Can B on MD4's - I would make use of A&B before using C or D. Maybe check the updates in the following release notes for Iqan 6:

Thank you for the reply. This MD4-10 was a bit older, so I think it would've had the older CAN C/D hardware, and I think the firmware update was to correct issues with the newer CAN C/D hardware. We're going to throw a MD4-7 with V7.05 running to see if that fixes it.
It would be interesting to know some system information about the XC43, particulary reported +Batt level
If voltage goes down current goes up
In the System->Modules->XC43 menu the VBB on the XC43 matches the battery voltage (~25VDC without alternator charging).
We replaced the MD4 with a known good and V7.05.19 firmware and the overload on all of the outputs is still coming up intermittently, but it seems to be getting worse. They cycle power and then everything works for a little while until the overload errors come back.
Had them check resistance through the cabling to the solenoids and everything read OK (~21.8-22.3 ohms) and check resistance from each wire on the COUT channels to ground and didn't find any shorts (most readings ~4.9-6.7 Mega ohms, a few OL).
I really do not know what is going on with this system. I've never seen this before. We might try to throw in a DC/DC converter to supply a clean 24VDC to the XC43 and see if that helps, but after that I have no idea. Replace all of the wiring?
Any insight anyone has or ideas on what else to check, that would be greatly appreciated.
