Thanks--I was not aware that tach cables are now 100% electrical. I guess
the speedo cables will eventually go that route. I wonder if water has
gotten into his speedo cable--this note is to J. Perry
When you install the new speedo cable--place some electrical tape real
tight around any points where water could get inside the new cable. This
should keep water and grease from getting where you don't want it to go. I
made this comment since you mentioned the 18 degree temperature as having
such a profound effect on the cable.
