Cluster has lost the incoming CAN bus messages to tell it what the engine is up to.

Thank you for your reply, Martin.
I believe you’re correct, but I’m not familiar with how it can lose its connection, and how to repair it. Do you have any advice? I’m going through the fuses, and relays, at the moment. |

As you have an engine conversion, you're a non-standard set up and so looking at factory LR info won't help here.
You might have an issue with the module/controller which is running the dash cluster from the LT1 engine. You need to get support from the converter or the supplier of that module. ![]() ![]() |

Thank you. I’m a bit of a novice for defenders, it isn’t my usual project. The engine and work was done by wildcat, and I am unlikely to get a response there.
The gauges were working correctly, but the fault occurred when I was playing with the radio (probably coincidence). I’m not entirely sure what controller is used, as the car came to me with no written information. Can you help me identify the controller? Where is it commonly located? I have a spear tech ecu, and under the rh seat is a spear tech little box. I’ve read posts on this forum where other defenders have showed the same issue - no tach, hot temp, but the advice was to remove and clean a fuse (which seems to good to be true, based on my experience). ![]() Click image to enlarge |
