Hey guys just bought myself a 90' 3ln and noticed the tacho gauge and fuel gauge lights arent working just wondering if there is a fuse box on the bikes and if not any ideas as to whats the go!
Not sure bout the tacho gauge but for the lights prob just need replacement bulbs....replace them all with slightly more powerful ones, its worth it.
Tacho appears to be supplied with 12v direct from the ignition switch and the only fuse in that line will kill the bike as well.. The signal line comes off the ignition pulse to the spark coil.. No pulse means the bike won't run. I would suggest that you look for a bad connection at the tacho. I think there are connectors at/near the tacho. Otherwise the tacho is faulty..
