Proud owner of a nice, stock, 83 R65. Cleaning up nicely. Original blue paint with the silver pin stripping. Tach not working. Cleaned the connector plug, no change. Headlight, turn signals, neutral light, generator light, all functioning. Any suggestions as to where to start? Is this common? Grounding issue, tach dead, etc? I did notice a connecter attached to green with brown stripes wires just sitting out between the gauges, but don't see an obvious place to plug it in.
Bike runs fine, idles smoothly. Do not want to fry the ignition module.
