[TR] TR3 wiper adjustment

[Frank Fisher]

i checked that the wiper spindles on my tr3 where working and self parking.
i
then fitted my wiper arms and blades.
with the blade at approximately
horizontal position on the windscreen.
turned on the wipers and they go across
the windscreen ok but on the return stroke they went way past the horizontal,
off the windscreen and on to where the lower windscreen to scuttle
weatherstrip would be if i had one. they then want to complete the cycle and
self park at the horizontal position again.
how do i adjust please?
thanks
