Worth a try and worth doing even if it’s not actually the problem. Lots of people change them regularly as a matter of course as routine maintenance. Cheap to buy, easy to replace.
Never had a can bus on it, did yours lose the neutral light, it flashes on when i first turn the ignition on, but off once the cluster settles
Cannot recall Jim, but if you havent plugged a canbus lead, then its not that. I never knew Id initially plugged it in wrong way round until I removed the lead and saw the errors. With the lead on I got no errors, so I put 2 and 2 together and went Doh!
I wonder if there is any other earths on the bike, i,ve cleaned the ecu one, main earth to engine and battery terminals,
Really clutching at straws now, been through starter connections earths, checked and cleaned, pulled the dash pod off, checked and cleaned, all fuses etc, got complete seat unit off and went through all connectors around there, pulled apart sprayed with cleaner then back together, cleaned ecu earth and heat sink on back off ecu,tried to trace earth on ecu, but that goes into the harness, not sure where that comes out, couldnt find an earth on the reg/rec, guessing that just earths through the body onto frame
It may have once had a cracked screen or still may. This is a fairly ccommon issue and the previous owner may have taken it apart to fix/inspect.
it might be an innocent repair but often it's more like "no smoke without fire" from memory. https://www.google.co.uk/search?saf...1.1.64.psy-ab..0.1.70...33i10k1.0.tpU3P-j7FDI
Plugged the dash back in, guess what, they wont light up, double checked everything and still wont work, wonder if its been the clocks all along, f$$k knows where i go from here
I had a similar issue returning to my 1000DS left for an hour while raining, different instrument of course. I tried the immobiliser ring to start with but no luck so unplugged/plugged in dashboard in desperation and it worked. Might be worth unplugging again and carefully looking for any signs of corrosion (often green) on connector pins. I've even used contact spray sometimes with luck although I hate spraying it on anything plastic generally from past experience. Thinking of desperate measures here (understandable looking at the availability/cost of your replacement instrument yesterday) but you could try removing clock/dash and bringing indoors and putting somewhere warm for a day or two.
