Attention ALL Electrical Guru's

I could really use a hug ;)

Here you go, Amigo!

The plot thickens. Checked the plugs on back of guages per Hanso's suggestion. All clean and dry. Greased, reassembled. Turn on key, no idiot lights, no sweep, same as before. With key on (engine not running) unplug engine management relay. Idiot lights come on, tach sweeps, idiot lights go off except neutral and low fuel, (they should be on). Plug relay back in, they go off. WTF ? Pull battery cable, unplug ECU connectors clean and dry, already greased. Tried reloading the tune out of desperation. No joy. Went for a ride, runs fine, speedo works fine even though it never sweeps now. Tried putting my 10 amp battery charger on in case it was low volts. Never goes below 12.5 volts. I wish had some documentation on how the sweep is supposed to work. There appears to be a problem in the can-bus system. It's gonna be hard to fix without knowing how it works. Odometer still very dim and trip meter still resets when key is cycled. Jiggled everything I could find (even my dong just in case). I'm rapidly running out of ideas. My baby's dying and I can't help her :(
 
She's not dying. Just conserving energy in the garage to have more available on the road ;)
Did you try a new relay or just the same one you pulled? How's the relay block and wires look?
 
Have you tried installing a Carpenter kit? Sounds to me like she's showing you she feels lethargic and has no energy but is just too scared to ask for another 100 ponies...women can be fickle remember
 
Ain't nothing worse than 'lectrical problems!!!
Feeling your frustration, Amigo!

THIS sounds like either a dodgy power (or maybe earth) wire/connection to the SPEEDO OR A DYING SPEEDO. The fact the trip cycles SUGGESTS its the permanent power supply that fails as TRIP data is not being preserved. But this could be INTERNAL.

Fred - Do you have any other electronic speedos lying about? - There are folk who've fitted different Speedos so we know they'll work. It'd be away to know if it's the instrument or feed to it. I Have a spare set of clocks for mine (JUST IN CASE) and one or two generic things lying about for this sort of debugging.

I'm not sure we OLD R3 users have a CAN-BUS do we? If so it can only be the ODO display.
 
I tried moving the relays around. All the relay terminals are clean and greased. @barbagris I agree it could simply be the speedo dying. Whats puzzling is that the entire sweep / idiot light test sequence has disappeared, unless I unplug the engine management relay. Then it does the test sequence fine with the exception of the speedo not sweeping. As for can-bus, I'm not sure either. I thought I read somewhere they did. There are an awful lot of wires going to the guages. You wouldn't think you'd need more than a couple if it were can-bus. I'll have to pick up another speedo for test purposes.
 
As I mentioned In another tread - I would take the instruments to an automotive instrument service guy to diagnose and test the gauges as the problem would most likely be in the gauges, but the gauges could also be reporting exactly what it is being sent in a bad signal/voltage etc sadly this will be a process of elimination.
