ive got a 2008 gv125 that I’m fixing up and rebuilding. After taking apart the gauge cluster and cleaning it up and the tach isn’t working. If I play with the connector (colored blue) then sometimes it comes to life but as soon as I leave it it goes back down to 0. I think I’ve got a loose wire but can’t find what color the wire is so I can check the whole line.
thanks in advance for your help!
