Indicator light & Tach problems

Can anybody help me ? What the heck is the little Lightning bolt/ arrow indicator for . It comes on intermittenly . On my 05 it is in the center display that houses the BC computer . It is to the right of the clock & next to the 0 . Come to think of it what is the 0 for ? Since I am posting , how big a job is it to take the Tach out. Mine is working intermittenly . The little black cap that was on the center of the needle came off & is now sitting at the bottom of the display .

Re: Indicator light & Tach problems

Oh, boy.. you've got your hands full. The tach is probably messing up because the connector needs to be replugged on the dash unit. The dash unit is sealed... but you can take it out.. you will have to remove the dash and upper dash covers. When you have it out, you can remove the face plate clear plastic cover.... then replace your tach indicator part....

BE CAREFUL to NOT get the inside of the cover dirty... mine had to be replaced because the dealer could not clean up fingerprints... and each of the "new" ones (theyordered 4) was damaged when they tried to clean them too.

The "0" is probably your gear indicator.

The lightning bolt... I don't know... is it to tell you the ABS unit is cycling through it's diags??? I'm not absolutely sure.. I can't find the description in the books. Could be it is the "BC self test.." or testing the bike lighting....I just don't know... yet.

wait.. here it is... The "lightning bolt" is detailed on page 68 of the Riders Manual... it is the EHCS (Electric Hydraulic Center Stand) test.....

Re: Indicator light & Tach problems

Thanks for trying . It looks like I am going to have my hands full taking the dash apart . I'm not sure when I am going to try . As for the lighting bolt / Arrow . I still don't know what it is for . You are right the 0 was the gear shift indicator Doh!! I look at it all the time . But the symbol that I am talking about only comes on when you first turn the ignition on & then goes out . I have seen it come on a couple of times while I was gearing down , But I can't seem to see any reference to it in the manual . I have looked at the section for the BC . This symbol is right next to the gear shift indicator in the BC display
