2009 SV650s Tachometer not working
Finally got the bike to start and took it out for a ride. It is such a blast to ride this bike compared to my precious zx6r.
Everything works great and now I am trying to figure out why my rpm needle does not move at all. The speedo works as well as the brights and turn signals. Where to check |

Re: 2009 SV650s Tachometer not working
The tachometer gets its signal from the ECU, brown and black wire. Either the wire is broken (most likely), the tach is dead (less likely) or the ECU has a fault (least likely).
You'll need a meter, you can use it to check for continuity of br/bk wire on ohms range between ECU and gauge and you can get a rough idea that you're getting a signal by putting it on AC volts, black lead to the battery (neg), red lead to back of gauge plug (br/bk wire) - start the bike and you should see a couple of volts, varying as the revs change.
