A technical question from me. One the rear nearside of the wheel on the E-15 there is a spring loaded adjustment screw, which is near the top of the rear brake operating arm. What does this do please? There also seems to be a regeneration effect when you apply the rear brake. Just pulling the lever enough to put on the brake light switch gives a retarding effect, and the voltage increases.
Finally, is there a chart which shows exactly what the symbols do on the speedo panel. There is the volts, speed, time and distance, and indicator repeater, but does the battery symbol have any function?
And do you have a service manual with recommended service checks etc?
