Hi There, I’m new here but just reading a few threads I’ve been helped immensely.

I am posting this thread to explain to peoplewhy the guage/instrument cluster is cutting out. (Most times)
Recently I had my Elise at the dealership & they couldn’t find the fault, I was lucky enough to be put into contact with a circuit board specialist in between the dealership & my home.
He explained that the solder used in mass production cars must be “non lead” solder for legal purposes.
Therefore the solder becomes extremely brittle when it’s being heated up & cooled down through normal weather changes.
He fixed my cluster by removing the solder & dry joints where the plug Joins the board, replacing it with more durable lead based solder.
This is not Lotus being “cheap” or not caring about components. It just illegal to use lead based solder in any kind of mass production of parts.

hope this helps & fixes the issues

I re-soldered my gauge cluster and I will also say that lotus used a very small amount of solder in the first place. After i removed the old solder and added new I probably doubled the amount of solder on each broken connection. I have done soldering a few vehicle instrument clusters (chevy trucks and ford mustangs) and they have drastically more solder at each connection (the actual stepper motors fail).
