It might take a bit of searching at the online manuals, but often there are some step-by-step diagnostic procedures given.
speedo cable is either misalligned or worn. replacement is the most reliable fix although you may get lucky from a junkyard. be very careful taking the cable off at the gearbox end. with some hondas, if you don't do it right, the drive gear can drop into the gearbox, and that's a world of hurt you want to stay /well/ away from.
Possible problems and solutions.
The cable connection behind the dash came loose. Solution: Reattach it. The cable connection on the gearbox came loose. Solution: Reattach it. The pulser or its driver is dead, which is unlikely. Replace it. The speedo needle is miscalibrate, recalibrate it. The gauge's solder joints are oxidize, redo it.
Thanks for your help. I appreciate it.
