1987 F800 speedometer doing double time.

mardi 29 septembre 2015

Speedo indicating bout 2X actual. Estimate pegs @ 40-45 mph. Operates smoothly and returns to 0 when stopping. Electronic unit. Same in Hi or Lo range. From info: speedo gets signal from VRM sensor @ end. of tranny - found it. From 2-speed axle control info: speedometer adapter in play in low range. Info reads like this is for mech speedo and a relay actually moves some gears driving a cable. Anyone know how electronic speedo gets range adjustment. Can't find the speedometer adapter shown.
