Here's the scoop: Bought a bike with the upper fairing/gauges damaged. Replaced the gauges and everything works when the key is turned on -- needle goes to redline then to zero, lights/displays work but when the bike is started the tach does not register any rpm (everything else works). Looked in other similar threads and checked the fuses -- they are all good, plug is in back of cluster solid, no damage to wires (i replaced upper wire harness). Any other suggestions or things i should be checking? Thanks.
