Rev-counter recalibration/reset

Squeaky back brake? Hard to control at 30mph/40kph?

Rev-counter recalibration/reset

Post by lew-hand-93 » Thu Apr 09, 2015 8:29 pm

Hi guys

Jump started my 990 a few weeks and it looked the battery was knackered as it struggling to idle and the clocks where constantly going off and resetting.

So I left it ordered a new battery and now it runs and rides fine but the rev counter does not do its sweep when you turn the ignition on and it's not giving the correct rev readings.

The digital dash is fine so is there anyway I can recalibrate/reset the rev counter?

I've shorted the battery calls to completely drain the bike and removed the fuse and switched the ignition on/off but still the same.

Any ideas?

Check the connectors at the Dash, also do a search on dash on the forum as there are a few posts where condensation has corroded the printed circuit pins causing dry joints within the dash cluster.

Hopefully it is something as simple as that just haven't got round to it.

If it is that it will he weird as it's only happened since the battery and it hadn't been washed for a good while before that

Strange one that ? I have had my share of dash/moisture issues but it has always started with fading digits on the LCD followed by them disappearing completely and the rev counter packing up. I would still have a look inside the unit for signs of moisture/corrosion.

Unplugged/plugged the speedo today and didn't solve anything so decided to take it apart to see if there was anything obvious.

No signs of any dust or moisture and the the joints appear to be ok.

I even plugged just the PCB incase it was being obstructed but the needle was the same.

One thing I have noticed is when the ignition is turned on it moves counter clockwise slightly?

Do you think it could be anything when I've wired the new battery, does anyone know where the counter readings are taken from on the engine?

Only other thing I can think of is the needle motor itself. It looks replaceable so might try and contact the manufacturer or a speedo repair shop to see if they can do anything.

Does anyone know the manufacturer of the speedo, I can remember it beginning with an F?

Had the speedo sent away for repair to which the motor/controller was replaced but it hasn't worked.

Does anyone have the pinout for the 32 pin speedo connector so I can trace back the rev-counter cable?
