Warning; this is a one cup of coffee long query, quit now if you're busy!
13 plate Glee (11k miles) no speedo LCD and no tacho, no ODO, no fuel display etc. Headlight warning light OK, indicator telltales OK, ABS warning light OK
The story so far:
I ride all weathers and the bike sits out at work, rain or shine. Last winter the speedo LCD started displaying random speeds unrelated to the bike speed. Other instruments OK.
Took the multi plug out of the back of the instrument unit, full of water. Dried, contact cleaner, reassembled with sealant round rubber boot. Everything now working fine. Hooray.
Several months later, same problem recurs. Same remedial process. More waterproofing, hood put over plug. Success, all working again.
Move on 2 more months; while riding whole instrument unit lights up like a Christmas tree for a second, then speedo becomes unreadable (not random numbers but random LCD elements)
Same remedial process but no sign of water and no fix.
I then followed Greywolf's advice on another string and checked all connectors from the sensor forward including the multi blocks behind the radiator, cleaning spraying and re-assembling. Nothing.
I continued riding for a couple of months using a GPS for speed information. During this time the random LCD elements started up dim and got brighter but eventually didn't come on at all.
Eventually no LCD light at all and the tacho does't move including no sweep on fuel pump priming.
This is where it gets embarrassing; I self diagnosed a malfunctioning instrument unit and bought a brand new one. I had to sell a kidney to afford it!! £466 just for the internal unit, no casings.
Fitted.................. no difference. At this point I am considering pushing the Glee over a cliff, but before I do so I thought I would ask for help here, before I admit defeat, sell another organ, and take it to a dealer
Can anyone suggest other things I can check, I am not good with electricals so be gentle with me!
If you have read this far, thank you!!
