Re: Erratic Rev counter readout

[jtrealty@xxxx]

The first thing to do when you have erratic reading gauges is to check 
and clean all connections. Pay particular attention to all ground 
connections. There is a major grounding point on the frame alongside 
the left front wheel. Remove the wheel, remove the wires and make sure 
that the connections are all clean and that the paint on the frame or 
rust isn't interfering with the connections and that it is tight. You 
can also remove all of the fuses one at a time and clean the contact 
points and tighten up the clips that they fit into. Check that the 
proper size fuse is in the correct spot, don't take it for granted as 
someone could have stuck the wrong size in or just switched them by 
mistake. For the tach you also should check connections around the 
motor for tightness and corrosion. On older cars very often the 
trouble is in the connections, not the part, but the simple act of 
changing things has the effect of "fixing" the problem because as you 
plug and unplug connections it cleans them.
