Hi Guys, I just finished the fun task of renewing the rear axle wheel bearings and oil seals, and had the usual fun trying to remember how to put the brake shoes back.
Anyway, I tried the 10 second ignition on, but sadly no improvement with the high RPM reading on the Tacho.
Will take the tacho out soon and try the dip switch trick.
Cannot find anything wrong with the connectors.
Thanks kindly for all the advice.
