MES Control Panel manual

Hi all, newbie here.
Recently bought a 2009 Nuevo with MES controller that keeps crashing and needs frequent reset via the push button.
I'm looking to get hold of a manual/wiring-diagram/pinout description for the MES controller. I did see some older posts where somebody has posted a manual, but the document has now time-expired.
I'm a retired electronics engineer, so my initial plan is to add power-supply filtering and signal-cable filtering to try to keep out electrical interference.

Thanks for looking

Hi Bunson
Welcome to the forum from Bridington.

Some versions of the MES control panel require a lithium battery, which requires replacement every few years. Have you checked to see if this is all that is needed? The documentation that I have states that a CR1620 is required, but be warned - that may not be true of all models.
